Description
Technical field
It the utility model is related to air pressure and Density Detection equipment technical field, and in particular to a kind of skyscraper air
Pressure and device for detecting density.
Background technology
Atmospheric pressure is the atmosphere that earth surface is made up of covered with a thick layer air, the thing in atmosphere
Body, it is subjected to pressure caused by air molecule shock.It can also be expected that atmospheric pressure is object in atmosphere by atmosphere
The pressure acted on caused by self gravitation on object.
Because centrifugal force acts on, away from the place that earth surface is near, earth attraction is big, the dense degree of air molecule
Height, the frequency height of body surface is struck, resulting atmospheric pressure is with regard to big.Remote place, earth attraction away from earth surface
Power is small, and the dense degree of air molecule is low, strikes that the frequency of body surface is also low, and resulting atmospheric pressure is with regard to small.Cause
The atmospheric pressure of this different height on earth is different, and the higher atmospheric pressure in position is smaller.In addition, the temperature of air and wet
Degree also has an impact to atmospheric pressure.
It is the long-term average atmospheric pressure regulation on 45 degree of sea level (i.e. height above sea level is zero) latitude in physics
For 1 standard atmospheric pressure (atm).This standard atmospheric pressure is certain value.Its value is millimetres of mercury=1 of 1 standard atmospheric pressure=760.033
Technical atmosphere=1.0133x10 5 power pa=0.The generation of 10133MPa atmospheric pressures is the result of terrestrial gravitation effect,
Due to terrestrial gravitation, air quilt " suction " generates pressure to the earth, maximum close to atmospheric pressure at ground.Meteorological Science
On air pressure, refer to the weight (atmospheric pressure) of suffered big gas column in unit area, that is, big gas column institute in unit area
The pressure of application.The unit of air pressure has two kinds of millimeter and millibar：The unit of air pressure height is represented with mercury pressure, with millimeter
(mm).Such as air pressure is 760 millimeters, exactly represents pressure caused by atmospheric pressure and 760 height mercury at that time
It is equal.Another kind is the millibar (mb) often heard in weather broadcast.It is with suffered air column pressure in unit area
Size represents the unit of air pressure height.1 millibar=1000 dynes/cms (1 bar=1000 millibars).Therefore, 1 millibar just
Represent the power by l000 dynes in l sqs.Equivalent to 1013 when air pressure is 760 millimeters.25 millibars, this gas
Pressure value is referred to as a standard atmospheric pressure.
Air pressure is changed with air height.Height above sea level is higher, and atmospheric pressure is smaller；The height above sea level difference of two places is more greatly different,
Its draught head is also bigger.The weight of big gas column is also influenceed by variable density, and the density of air is bigger, that is, unit volume
The more, its caused atmospheric pressure is also bigger for the quality of interior air.
It is more thinner to high-altitude because the quality of air is more near the ground more intensive, so changing value of the air pressure with height
It is more bigger close to ground.Such as in low layer, often rise 100 meters, air pressure just reduces about 10 millibars；In 5~6 kilometers of high-altitude,
Often rise 100 meters, air pressure reduces about 7 millibars；And to 9~10 kilometers of high-altitude, often rise 100 meters, air pressure just only reduces about 5 millis
Ba Liao.
Air pressure is not changing all the time.Under normal conditions, air pressure every morning rises, and declines to air pressure in afternoon；Often
Year winter air pressure highest, annual summer air pressure are minimum.But sometimes, such as when a cold wave influences, air pressure can raise quickly, but
Cold air one is crossed air pressure and slowly reduced again.
Conversion relation between height above sea level and air density and temperature：
1st, according to atmospheric pressure and atmospheric density calculation formula, and air humidity empirical equation, atmospheric pressure, sky can be drawn
The relation of air tightness, humidity and height above sea level.
| Height above sea level (m) | 0 | 1000 | 2000 | 2500 | 3000 | 4000 | 5000 |
| Relative atmospheric pressure | 1。000 | 0。881 | 0。774 | 0。724 | 0。677 | 0。591 | 0。514 |
| Relative air density | 1。000 | 0。903 | 0。813 | 0。770 | 0。730 | 0。653 | 0。583 |
| Absolute humidity (g/m3) | 11。00 | 7。64 | 5。30 | 4。42 | 3。68 | 2。54 | 1。77 |
Note：Atmospheric pressure is 1 under standard state, relative air density 1, absolute humidity 11g/m3。
As can be seen from the table, height above sea level often raises 1000m, and relative atmospheric pressure about reduces by 12%, atmospheric density
About 10% is reduced, absolute humidity reduces with the rise of height above sea level.Absolute humidity refers to that the gas institute of per unit volume is aqueous
The weight divided, with mg/L or g/m3Represent；Relative humidity refers to the ratio between absolute humidity and the filament saturation state water vapour content
Expressed with percentage.
2nd, the relation of air themperature and height above sea level
In the case where being screened without thermal source, nothing, air themperature reduces with increasing for height above sea level.General Study is gathered
Temperature and height above sea level relation：
| Height above sea level (m) | 1000 | 1500 | 2000 | 2500 | 3000 | 3500 | 4000 |
| The highest temperature (DEG C) | 40.0 | 37.5 | 35.0 | 32.5 | 30.0 | 27.5 | 25.0 |
| Temperature on average (DEG C) | 20.0 | 17.5 | 15.0 | 12.5 | 10.0 | 7.5 | 5.0 |
As can be seen from the table：In general, height above sea level often raises 1000m to air themperature, and maximum temperature can drop
Low 5 DEG C, mean temperature can also reduce by 5 DEG C.
Become increasingly popular with meteorological and health science, people are to the meteorological elements such as temperature, humidity, wind, sunshine and health
Relation all compare concern and be familiar with.But to air pressure, people typically compare and ignored, and also do not have air pressure key element in weather forecast.Thing
In reality, when air pressure is too low, air pressure change is excessive in the too high or short time, adverse effect on human health or obvious
's.Influence of the air pressure to health, sum up and be divided into two physiological and psychological aspects.
Influence of the low pressure to Human Physiology mainly influences the supply of oxygen in human body.People needs about 750 millis daily
Gram oxygen, wherein 20% be brain consume, because brain oxygen demand is most.When nature air pressure declines, partial pressure of oxygen, lung in air
The partial pressure of oxygen and arterial oxygen saturation of bubble all decline therewith, cause human body that a series of physiological reactions occur.With from low land step on to
Exemplified by high mountain, because air pressure declines, body just accelerates breathing and blood circulation for compensation anoxic, is short of breath, increased heart rate
Phenomenon.Due to human body particularly cerebral anoxia, dizzy, headache, Nausea and vomiting and the symptom such as powerless, nervous system there is also
Also obstacle can occur, or even pulmonary edema and stupor can occur, here it is " altitude effect " generally said.
In anticyclonic environment, human body respectively tissue gradually by nitrification (after typically working 5-6 hours under high pressure, people
Body is just by nitrification), when human body comes back to standard atmospheric pressure, superfluous nitrogen is just discharged with exhaling in vivo, but this process
Compare slowly, if returning to standard pressure environment suddenly from hyperbaric environment, in fat the nitrogen accumulated may some stop
Stay in human body, and expand and form small bubble, block blood and tissue, easily form aeroembolism and trigger illness, severe patient can endanger
And the life of people.
Influence of the air pressure change to health, more show the life of high pressure or the circulation weather situation representated by low pressure
Into, disappear or mobile aspect.It is mostly rainy weather under depression circulation situation, the change of wind is obvious；And in high compression ring
Under manifold gesture, mostly fine day, weather are more stable.The Medical Meteorological expert of Japan is by the research discovery of several years, most of lungs
The degree and depression circulation weather that tubercular's hemoptysis, bloody sputum aggravate have close relationship.When conditions of patients deteriorates, there is 90% to be
Occur under depression circulation situation, have more than half when low pressure is passed by.And under high pressure Circulation, branch gas
Guan Yan, children's asthma disease are easier to break out.When high pressure circulation shifts to Japan, Japanese asthma patient starts to increase；Work as high pressure
By when, number of the infected just peaks value；After high pressure removal, asthma patient in Japan just substantially reduces.Why
Such situation occurs, is because under high voltage control, is air-dried, become a fine day that wind is small, the radiation cooling at night is easily formed
The anaphylactogen such as inversion, dust, Mycophyta, pollen, spore, easily stagnated in surface layer, so as to induce the breaking-out of asthma disease.
Meanwhile the change of air pressure can also influence the psychology change of people, make one to produce oppressive, gloomy mood.For example, low gas
Hot and humid weather (now air pressure is relatively low) before the sleety weather of pressure, especially summer thunderstorm, the bad people of cardio-pulmonary function
It can feel bad extremely, normal person also has a kind of sense of depressed discomfort.And it is this feel suffocated and constrain, the vegetative nerve of people can again tended to
Anxiety, adrenaline is discharged, causes blood pressure rising, palpitating speed, be short of breath；Meanwhile cortisol is decomposed out, cause
Gastric acid secretion increases, infraction easily occurs for blood vessel, blood glucose value may also rise suddenly.There is scholar high to monthly air pressure minimum period and death
Peak has carried out comparative study, as a result finds that 89% peak mortality was appeared in the period of barometric minimum.
Being influenceed by attraction of gravitation, the mankind always think there is kind of the sensation of " pragmatical " close to the earth, have a sense of security,
And a kind of unstable sensation is then had in aerial high building, certain oscillatory is inherently had plus high-rise, such as
Fruit adds the traditional concept of some old men to this than more sensitive people, it is easier to is allowed to produce a kind of uneasy psychological shadow
Ring.Simultaneously as objectively high aerial air is thinner than lower, amount of oxygen is reduced, and attraction of gravitation has also been reduced, to
The patient of some illnesss have really be not suitable for part, especially suffer with chronic bronchitis, heart disease, angina pectoris, the cerebrovascular with
And internal organ have the patient of lesion, it is high unfavorable to its disease development in the air to live in for a long time, it is possible to can aggravate the state of an illness.
Human body has inseparable substantial connection with air, and being not only as human body needs to breathe and adjust body temperature.
Air also has a kind of effect for being not easy to be therefore easily perceived by humans for human body -- the pressure of air.One outstanding swimmer,
No breathing is not a problem also in a few minutes, but if without atmospheric pressure, does not survive within several seconds probably yet.It is generally believed that
The atmospheric pressure of standard is every square centimeter 1.0336 kilogram.The human body of one adult altogether will be by the atmospheric pressure of 12-15 tons
Power.But because atmospheric pressure is always from each different direction effect and same point, and size is identical, each two size
Identical pressure is just cancelled out each other, so human body just imperceptible so big pressure, but it be really there is.Just
For breathing, when inspiratory centre excitation time, the diaphragm contraction of muscle between thoracic cavity and abdominal cavity, Thorax volume are made by nervus phrenicus
Expand, lung qi bubble also and then expands, and declines air pressure therein, and be less than external pressure.Then outside air is in atmospheric pressure
In the presence of, lung is flowed into from nostril and mouth, is steeped into lung qi.The situation contrast of expiration, because Thorax volume reduces, lung
Interior air shrinks, and internal pressure is more than outside, and gas just breathes out in lung.
Upper atmosphere pressure reduces mainly has both sides to influence on human body：Atmospheric oxygen partial pressure reduces caused height
Vacancy oxygen (see chapter 3)；(the violent influence of change of environmental pressure run into Aero-Space also wraps hypobaric physical impact
Including including).When atmospheric pressure reduces, two classes influence to occur simultaneously, but chief threat is still high altitude anoxia.On modern military aircraft
Oxygen supply equipment can protect the influence of anoxic；Ventilated type manometric capsule then has to anoxic and low pressure physical impact
Protective action.But such as breakage occurs for cockpit, occupant can be directly exposed under low pressure again in cabin, although its chance of occurrence is not
More, if once occurring, the lighter influences normal work ability, forms accident proneness, and severe one may cause aircraft accident.Furthermore army
" low voltage difference system " is used with aircraft pressurized cabin, even if cockpit is intact, cockpit pressure is relatively low during due to high-altitude flight more, it is also possible to
A series of low pressures are caused to influence problem.Ventilated type manometric capsule of the regenerative positive pressure cabin of manned spacecraft than aircraft
Play the role of preferably to protect anoxic and low pressure physical impact.But depressurized before spacefarer's extravehicular activity in cockpit ladder
Under the conditions of, or in extravehicular activity be in space suit lower pressure under when, can also occur low pressure influence problem.Low pressure and air pressure
Why drastic change can produce physical impact to body, be due to that living organism morphosis aspect has following inherent feature.
(1) gas is contained in hollow organ such as intestines and stomach, lung, tympanum and nasal sinus.When environmental pressure reduces, intracavity gas
It such as can not in time discharge, volumetric expansion is just occurred according to the expansible degree of organ walls or tissue lumen internal pressure phase occurs
To elevated change.
(2) a certain amount of gas is dissolved with tissue and body fluid, when environmental pressure is reduced to a certain extent, these solution gas
Body may isolate, in the blood vessels, outer formation bubble.
(3) body fluid is mainly what is be made up of moisture.Water under environmental pressure decreases to or below body temperature steams
During air pressure, water just occurs " to seethe with excitement ", forms a large amount of steam.
(4) during air pressure drastic change, because the rate of change of ambient pressure is very big, the volume or pressure of gas in some hollow organs
Also rapid change, according to the difference of its physiology anatomical features, has two class problems than more prominent：Lung compares stomach with extraneous traffic pipeline
Enteron aisle is much more complex, and lung tissue is again more fragile, so, the volume expansion occurred when air pressure reduces rapidly, lung will be produced
Life significantly affects；The sclerotin wall of tympanum can not swollen, contracting, with the pipeline that communicates of the external world special knot with check valve sample again
Structure, in the pressurization from high-altitude descending, when can not smoothly enter intracavitary such as ambient atmos, that is, occur at tissue lumen internal pressure power
In the change of relatively low state.In the presence of nasal sinus occurs mucous membrane swelling or has neoplasm to the opening of nasal cavity,
The pressure change in similar tympanum can also occur from the pressurization of high-altitude descending, in nasal sinus.
In above-mentioned items, first three items depend primarily on the degree of atmospheric pressure reduction；Section 4 depends primarily on atmospheric pressure
Power rate of change, the degree and place also changed with air pressure highly have certain relation.Therefore, skyscraper high air pressure is studied not only
The safety coefficient of building is had influence on, and has influence on high residential building personnel's personal safety.The wherein water system of high-rise
