基本解释

Medium viscosity, medium strength, applicable to sealing hydro-pressure and gas-pressure tube threads.
中粘度，中强度，用于液压和气动客路螺纹密封。
The paper presents a design of passive heat-switch between pressure tube and calandria tube of Thorium-based Advanced Nuclear Energy System.
提出了一种用于钍基先进核能系统压力管与排管之间的非能动热开关设计方案。
Pressure Tube Rupture, Pressure Tube and Calandria Tube Rupture, Feeder Breaks, Pressurizer Relief/Steam Bleed Valves Fail Open, Liquid Relief Valves Fail Open, etc.
在事件树分析中，考虑了各种类型和位置的破口，如：压力管破损、压力管和排管破损、供水管破损、稳压器卸压阀/蒸汽排放阀故障开启以及液体排放阀故障开启等。

And what is inside the gas discharge tube is gas at low pressure.
气体放电管里,有处于低压下的气体。

Stratram would need to overcome a lot of challenges, particularly if squishy humans were among the things being transported into space: the track would need to be around 1, 000 miles long to avoid the kind of instant acceleration that could crush a human, and the train would need a low-pressure vacuum tube to travel through.
