Description
Technical field
The utility model is related to a kind of plant physiology experiment device, and specifically a kind of potato tubers water content is fast
Fast analyzer.
Background technology
Plant tissue water content is an index of plant physiology state, such as fruit, how many pairs of vegetables water content its product
Matter has an impact, and seed moisture content is more meaningful to safe storage.The principle of vapor is evaporated to using water heat, can be dried with heating
Dry method determines the water content in plant tissue.The method for expressing of plant tissue water content, often with fresh weight or the percentage of dry weight
Represent, also relative water content is represented sometimes.The latter can more represent its physiological significance.Plant relative water content can be with following
Formula is calculated:Relative water content(RWC)=(Fresh weight-oven-dried weight during sampling)/(Fresh weight-dry weight when expanding completely)×
100%。
Material locally resists the ability referred to as hardness that hard thing is pressed into its surface.Solid to external world resist by the local of object invasion
Ability, is the soft or hard index of the various materials of comparison.The different method of testing due to defining, so there is different hardness standards.
The mechanics implication of various hardness standards is different, mutually can not directly convert, but can be contrasted by experiment.Hardness is divided into:①
Scratch hardness.It is mainly used in comparing the soft or hard degree of different minerals, method is the rod for selecting the hard one end in an one end soft, will be measured and monitored the growth of standing timber
Material is streaked along rod, and the soft or hard of measured material is determined according to the position for cut occur.Qualitatively say, the cut that hard object is marked is long,
The cut that soft object is marked is short.2. penetration hardness.It is mainly used in metal material, method is by defined pressure head with certain load
Measured material is pressed into, the soft or hard of measured material is compared with the size of material surface local plastic deformation.Due to pressure head, load and
The difference of bearer duration, penetration hardness has a variety of, mainly Brinell hardness, Rockwell hardness, Vickers hardness and microhardness
Etc. several.3. sclerometric hardness.It is mainly used in metal material, method is a special hand hammer is impacted from certain altitude free-falling
The sample of measured material, and stored with sample in impact process(Then discharge)The number of strain energy(Pass through the rebound of hand hammer
Elevation measurement)Determine the hardness of material.
In penetration hardness determination method, it is divided into static load plunging and Dynamic load press-in test method again according to loading loading velocity is different,
The latter is also known as elastic resilience method.The general principle of static load plunging is:Using mechanical device by standard indenter under ordinance load
Detected materials surface is pressed into, keeps unloading after certain time, then measurement remains in a certain geometric sense of the impression of material surface,
Such as the area of indentation, depth of cup or impression catercorner length etc. characterize the soft or hard of material.Obviously, the area of indentation or depth of cup
Bigger, material hardness is lower.
Toughness is the ability that wear-resistant object, stretch-proof, resistance to compression enter etc., can also be called the ability of resistance to fracture.In elastoplasticity
Under the conditions of, when stress field intensity factor increases to a certain critical value, crackle just unstable propagation and cause Materials Fracture, this is critical
Or the stress field intensity factor of unstable propagation is fracture toughness.It reflects material resistance instable growth of crack and resists brittle failure
Ability, is the mechanical performance index of material.
The problem of prior art is present:Potato ball had both embodied the hardness of potato ball or embodied during crushing
Toughness, has no be converted to relative hydration amount determining device and survey using the measure of the mechanical characteristics such as hardness and toughness in the prior art
Determine the report of method.
