活塞-圆筒型高温高压容器在原理上是自由活塞压力计的变型,其工作压力可由外加载荷中扣除摩擦损耗后直接定出,故在高温高压研究中得到广泛的应用[1].但是这种容器的端面保护很不完善,容易使容器内衬出现横向开裂. 早期的活塞-圆筒容器使用时只有径向保护并无端面保护[2].Hall指
Piston-cylinder type high temperature and pressure vessel is a variant of a free piston type pressure gauge in principle, and its working pressure can be directly determined after deducting the frictional loss from the applied load, so it has been widely used in the research of high temperature and pressure [1] The container end face protection is imperfect, easy to make the container liner lateral cracking early piston - cylinder container only radial protection and no end protection [2] .Hall finger
