本文详细地描述了在30000kg/cm~2内测定物质P-V关系的装置及测量方法。采用了活塞式容器和机械压缩的方法进行测量。以KBr,KCl和铋在20℃时的压力相交点来标定容器内的压力,校正结果表明,容器内的压力和外力成很好的直线关系。容器和活塞等形变的校正是以光谱纯铁作为标准样品,在本容器内进行压缩试验,把测定结果和Bridgman的测定结果相比,找出差值作为样品在受压过程中,由于容器形变而引起的体积修正值。 工作中,测量了一些材料在常温下的P-V关系。
This paper describes in detail the device and method for measuring the relationship of substance P-V at 30,000 kg / cm ~ 2. Piston containers and mechanical compression are used for the measurement. The pressure inside the vessel was calibrated with the pressure intersection point of KBr, KCl and bismuth at 20 ℃. The calibration results showed that the pressure and the external force in the vessel had a good linear relationship. Vessel and piston deformation correction spectrum pure iron as a standard sample in the container compression test, the measurement results and Bridgman determination results to find the difference as the sample during compression due to container deformation The resulting volume correction. In work, the P-V relationship of some materials at room temperature was measured.
