In the analysis and calculation for the function of transient temperature and material strain, material strain and interference fringes, derived the amplitude and phase function of the transient temperature change and interference fringes, so as to provide the necessary conditions for detecting the use of spectral density function temperature.
Introduction Speckle pattern interferometry is a non-contact measurement method which is the object surface deformation of tiny measuring [1].The technology has already been widely used in components and the product should be mechanics experiments, new materials testing, mechanical structure vibration testing and other fields.
At the same time, with solid expansion found equation: (3) So： (4) That is: And because, for the tensile deformation of elastomer (5) After deformation get , finishing (6) Among them, to be of the object under test form variables, for the temperature of the material change coefficient and for the pressure of the materials for temperature change coefficient, for materials original length, for temperature variation.
So the measured transient temperature mainly depends on the change of the pressure coefficientand the temperature coefficient, namely the measured surface materials and their various parameters related with the deformation.

Many of medical applications require high mechanical strength materials for load-bearing, whose properties are largely dependent on their microstructural features, such as particle size, degree of particle size agglomeration and sintered densities [3, 4].
So the preparation of fine, single distribution and sinterable HA particle is the most important step in achieving a highly sintered ceramic material with desirable microstructure.
Materials and Methods In the microemulsion reaction, cyelohexaneane was used as the oil phase, while tritonX-100 as the surfactant phase, hexanol as co-surfactant phase, and an aqueous Ca(NO3)2 and (NH4)2HPO4 solutions as the water phases.
