叙述了微球高压充氢原理及聚苯乙烯塑料微球高压充氢系统,该系统可充入压力高达 1.0×108 Pa,并且利用调节液氦流速来控制系统温度。实验研究了高压氢气在低温下的相变行为及球壳材料的低温形变。
The principle of high pressure hydrogenation of microspheres and the high pressure hydrogen charging system of polystyrene plastic microspheres are described. The system can be filled with pressure up to 1.0 × 108Pa, and the system temperature can be controlled by adjusting the liquid helium flow rate. The phase transition behavior of high-pressure hydrogen at low temperature and the low-temperature deformation of spherical shell materials were investigated experimentally.
