Description
Technical field
A kind of acoustic velocity measutement field in being studied the present invention relates to high pressure state equation, and in particular to transparent medium major skock
The continuous measurement system and method for the adiabat upper body velocity of sound, can realize super-pressure measurement by impulsive sound.
Background technology
The response characteristic of material under high pressure for the earth and planetary physics, inertial confinement fusion and first principle
Multiple physical study fields such as modeling are of great significance.In the various characterizations of material response characteristic, the velocity of sound reflects small answer
The propagation characteristic of force-disturbance in the medium carries the various modulus information of material, is material under certain thermodynamic state
A kind of mechanical attribute is research material state equation, constitutive relation, phase transformation (including solid-solid phase-change) and substance composition etc.
Important means.In planetary physics and weapon physical study, pressure limit can reach million to ten million atmospheric level, and
Acoustic velocity measutement under so high pressure always is the significant difficulty that high-pressure physics research faces.
Impact compress is to obtain the main means of high pressure, and the principal mode of impact compress is shock wave, is not before shock wave
The substance of compression is compressed substance after shock wave, and the thickness of shock wave is very thin, it is believed that is that an interruption is jumped
Jump.It is connected from state after the different shock waves of normal temperature and pressure original state and just constitutes shock adiabatic curve.Impact is exhausted
The measurement result of the velocity of sound can directly calculate state equation Gr ü neisen coefficients on hot line.
In order to measure the velocity of sound of the material under impact compress state, needs to introduce small stress in state after shock wave and disturb
It is dynamic, measure the spread speed of microvariations in this state.Under uniaxial strain loading environment, disturbance that there are two main classes：It is laterally small
Disturbance and longitudinal microvariations, it is practical measure in mainly unloading disturbance.The famous shock dynamics expert Al ' of Russia
The forerunner for the Measurements of sound velocities in shock that tshuler professors L.V. are just has carried out various metals material early in nineteen sixty
Acoustic velocity measutement under 100GPa surges has carried out experimental study to laterally disturbance and longitudinal disturbance.Wherein lateral disturbance side
Method is to record the sparse permanent shock wave one-dimensional plane range to reaching sample rear surface of avris with streak camera, due at that time
Test condition under disturbance boundary measurement accuracy it is limited, therefore later stage research is mainly to pursue sparse longitudinal perturbation motion method
It is main.Nineteen eighty-two, McQueen, Hopson et al et al. improve the method for pursuing sparseness measuring longitudinal wave velocity, propose
Optical analysis greatly advances the research of the impact velocity of sound.Its principle is that bromofom etc. is introduced after sample under Impulsive load
Strong luminescence and the luminous intensity window material very sensitive to pressure determine rarefaction wave by the Strength Changes for recording luminous
Arrival time, and then provide longitudinal wave velocity and the body velocity of sound.After the nineties in last century, with high time resolution
Interference velocity measuring technique development, pursue the sparse time measure while can obtain corresponding particle rapidity, to
The velocity of sound on the corresponding unloading line of wave profile failing edge can be provided.The team that fluid physics research institute professor Tan Hua leads is rushing
A large amount of work has been done in terms of hitting acoustic velocity measutement, Typical Metals have been directed within 200GPa, to longitudinal wave velocity, body sound velocity
And the problems such as relevant intensity, phase transformation into a series of researchs have been carried out, have higher influence power in the world.At present, right
Main means, the maximum that this method encounters still are measured as with the longitudinal wave transition time in the acoustic velocity measutement on major skock adiabat
Problem is exactly to need the shock wave of a permanent propagation, since DIRECT ENERGY deposits (such as high power laser light, high energy particle at this stage
Beam etc.) generate shock wave stability be still unlikely to film flying hit compared with, either central collision or opposite direction collisions is required for
Ensure film flying itself state and thickness it is known that under these constraintss existing film flying actuation techniques (gas big gun driven flyer plates
8km/s, Magnetic driving film flying 30km/s) it is difficult measurement by impulsive sound (the especially Low ESR that satisfaction carries out high pressure section with chasing method
Sample) required precision.
Therefore, existing acoustic velocity measutement has the following defects：
The shock wave that disadvantage one, super-pressure stable state are propagated is difficult to realize, therefore the pursuit process of the propagation of disturbance can not be accurate
The really reflection velocity of sound.
The shock wave that stable state is propagated all is to be hit to generate with High Speed Flyer, and current pressure is reached the standard grade as millions of air
Pressure.Experiment will form the shock wave of higher pressure, typically with other type of drive, such as high-peak power laser, pulse power
The characteristics of device etc., these devices is the particularly stable shock wave being hardly formed.So driven method is not suitable for super-pressure
Acoustic velocity measutement.
Disadvantage two, only measurement sample back-surface side can not accurately provide shock wave front bending point to Sparse methods, also with regard to nothing
Method accurately provides velocity of sound result
The work of the former Soviet Union is that is measured is the shock-wave luminescence signal of free surfaces of specimen, is only capable of the front and back of resoluting signal appearance
Difference cannot be entirely clear the essential distinction for providing plane area and non-planar area, so the accuracy of identification of bending point is very poor, from
And velocity of sound result is also very poor.
Invention content

Specifically, the separation layer is made of heavy metal element, the base is made of aluminum.
Specifically, the relationship based on pressure sizing Yu material high pressure conditions, according to directly measuring obtained shock velocity
UsWith the sparse boundary of avris, pressure sizing C is obtainedb
In formula, CbFor the velocity of sound, UsFor the shock velocity actually measured, UpFor the satellite speed in propagation process of sound wave, α
For the angle of the tangent line and shock motion direction of the sparse track of shock wave avris.
