    • Disclosed are a device and a method for making an experiment on temperature characteristic of material. The device includes a small volume thermostat for maintaining temperature uniformly and an interferometer for measuring a length change according to a temperature change of a measured fragment. Material, which maintains inside temperature of the thermostat uniformly, is disposed around the thermostat. The material maintains temperature uniformly for a long time when phase is changed. A hole is formed in a front surface of the thermostat to allow beam to be transmitted, thereby measuring the length change of the measured fragment inside the thermostat. By measuring the length change in a noncontact way when beam is transmitted through the hole, the temperature characteristic of the material is tested according to temperature.
    • 公开了用于对材料的温度特性进行实验的装置和方法。 该装置包括用于保持温度均匀的小体积恒温器和用于根据测量碎片的温度变化来测量长度变化的干涉仪。 恒温器的内部温度均匀地保持在恒温器周围的材料。 当相变改变时,材料长时间保持一致。 在恒温器的前表面形成一个孔,以允许光束被透射,从而测量恒温器内的测量碎片的长度变化。 通过在通过孔传输光束时以非接触方式测量长度变化,材料的温度特性根据温度进行测试。
