【摘要】 总结了材料放气测试的各种方法:压力上升率法、收集法、称重法和气体流量法。开发了一种基于气体流量法的新法,不仅可以用于常温和较高温度,而且可以用于材料在低温环境下放气的测试,最低测试温度可以达到100K左右。此系统方便实用,具备较高的测试精度。更多还原

【Abstract】 Various methods to measure outgassing rate were summarized including the pressure rising rate collecting,weighing and gas flowrate.Based on the gas flowrate method,a new one was developed to measure outgassing rate,which can be used not only at room/high temperature but also at low temperature even down to about 100K.The measuring system is easy to operate and has a high precision.更多还原
