pressure tube

基本解釋

Medium viscosity, medium strength, applicable to sealing hydro-pressure and gas-pressure tube threads.
中粘度，中強度，用于液壓和氣動客路螺紋密封。
The paper presents a design of passive heat-switch between pressure tube and calandria tube of Thorium-based Advanced Nuclear Energy System.
提出了一種用于釷基先進核能系統(tǒng)壓力管與排管之間的非能動熱開關(guān)設(shè)計方案。
Pressure Tube Rupture, Pressure Tube and Calandria Tube Rupture, Feeder Breaks, Pressurizer Relief/Steam Bleed Valves Fail Open, Liquid Relief Valves Fail Open, etc.
在事件樹分析中，考慮了各種類型和位置的破口，如：壓力管破損、壓力管和排管破損、供水管破損、穩(wěn)壓器卸壓閥/蒸汽排放閥故障開啟以及液體排放閥故障開啟等。

And what is inside the gas discharge tube is gas at low pressure.
氣體放電管里,有處于低壓下的氣體。

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.
