Description

A kind of pressure testing gravimeter principle

Technical field

A kind of pressure testing gravimeter principle provided by the invention belongs to gravity apparatus instrument processing technique field.

Background technology

Pendulum gravimeter of the prior art, absolute gravimeter, static spring gravimeter, and the superconductive gravimeter of GWR company production, it all is the phylogenetic gravitational effect of power to the species distribution one-tenth of space lifting power effect, the mechanical function that on understanding, plays to the gravity field of regarding space-time character as, not considering the material of space lifting power effect and the relation of gravity, is that the gravity that the graviational interaction of object produced according to the field of force of the space-time character in the imagination is as the designed produced gravity meter of measuring object.Its defective, because this class gravity meter is indeterminate aspect measuring object, make the various drawbacks that aspect device fabrication, exist, brought many inconvenience for rocket, satellite, spaceship, the work of ground gravity network counterweight force measurement, and input cost is very high.

When on science, according to the Galileo mechanics relativity principle, to object definitions is that to be regardless of between the different material of species and states of matter the same barycenter body that forms that moves together be same object, confirm that the material of space lifting power effect is used to wear the ionosphere that holds, atmospheric envelope, layer liquid, the solid layer body that forms that moves together is the object of the earth, illustrating that newton does not propose the scientific development of gravitation before saying, this interior of articles layer liquid of the earth that Archimedes finds is transmitting even pressure to the acting force in extension space and this interior of articles flowable material of the earth of Pascal's discovery to all directions along radius, the mechanical property of interior of articles and the mechanics key element of shaped object have just been disclosed, the corresponding airtight power system that has disclosed infinitely great this naturality of plena in universe is a pressure system, and the structure of matter, a kind of has been that the narrow and small zone of being given exclusion by the leakproofness of particle of virgin pressure effect cans be compared to the weak material that has melted health, another kind is the particle that health is arranged that bears the pressure effect, also just illustrated simultaneously, before not having the clear and definite structure of matter and object relation, " field " notion that faraday becomes the form of power system to invent for the ease of the species distribution of explaining interior of articles different plant species and states of matter, and according to the different gravity fields that just have of the factor that forms power, magnetic field, general introductions such as electric field, and, shown any power internal system mechanical property it be exactly the mechanical property of interior of articles, it is to be the pressure field of media with weak material for a gravity field--belong to the weak material layer of this interior of articles of the earth.And pressure field aspect statics law is f ρ Δ H=-f ρ Δ H, the pressure field balancing effect principle that exists is: an object is the motion of (pressure field in) and static in another object, is that size that balanced capacity and the variation of this object density of pressure and opposite pressure in the pressure field at its place increases and decreases this ability makes it trend towards the motion of dynamic balance process and static when reaching dynamic balance.Gravity wherein, be can flow its inner object density of pressure field that object constitutes change with it is exerted pressure make a concerted effort greater than opposite pressure the time be in the power that displacement state produces along pressure direction, and the acceleration of gravity that obtains of the inertia impact of the continuous accumulated pressure of object motion.So only the force value with the weak material that plays original action of gravity is a measuring object, the mechanics rule that can fundamentally grasp gravity principle and be determined.

The present invention provides to be used for making the narrow and small zone of measurement is determined this gravity meter of gravity size by its pressure size like the weak material field of the weak species distribution one-tenth that has melted health principle for to address the above problem on science and technology.

Summary of the invention

A kind of pressure testing gravimeter principle provided by the invention, its purpose: with regard to the airtight power system by infinitely great this naturality of plena in the accountable universe of Archimedes-Pascal's discovery on the science is a pressure system, and the indicated structure of matter, a kind of has been that the narrow and small zone of being given exclusion by the leakproofness of particle of virgin pressure effect cans be compared to the weak material that has melted health, explanation simultaneously, in weak material pressure field, although various materials its linear expansion and shrink value and be in stable under constant temperature, when changing its pressure that bears weak material size, the material linear expansion and shrink value thereupon the effect of this pressure size level off to changing of balancing each other, the liquid mercury under the vacuum state for example, by the gravity of the earth to microgravity (minute-pressure power) position, its linear expansion and to shrink value be that pressure size with the weak material of bear will change, based on this variation, it is the gravity meter principle that measuring object is grasped the gravity size that a kind of weak material pressure value with original action of gravity is provided.Principle mainly is the optical loupes by being provided with, read in the constant temperature enclosure with the optics glass become above have a miniature number, inside is equipped with the linear expansion of mercury and is shunk and shows the meter demonstration, by P _C=K (P _W1+ P _W2)/P _SR ²This fluctuation effect decision when the pressure P of weak material to its interior liquid mercury _SWhen reducing, and the source of resonant excitation body of molecule repels pressure P in the liquid mercury _CRelatively increase and liquid mercury is expanded and at P _SThe source of resonant excitation body of molecule repels pressure P during increase and in the liquid mercury _CReduce to make liquid mercury to shrink this relatively and level off to the value that balances each other and change, grasp weak material field pressure P _SSize, grasp simultaneously by the object in the pressure of pressure field balancing effect (f ρ Δ H=-f ρ Δ H) decision with it is exerted pressure make a concerted effort greater than opposite pressure the time be in displacement state along pressure direction and produce the gravity size.And the gravity meter made of principle according to this, not only overcome gravity meter of the prior art and blindly produced the various unfavorable factors that cause because of the indeterminate measuring object of development personnel, and, be to ensure under the definite prerequisite of measuring object, be convenient to rocket, satellite, spaceship, the ground gravity network accurate surveying work to gravity, input simultaneously reduces cost.
