  1. Chart s technicians provide : helium mass spec leak testing, vacuum loss investigation and repair, and turn - key installations

    查特提供的現場服務包括：氦檢漏，真空檢測和維修，以及「交鑰匙」安裝工程
  2. Secondly, the cfd method is used to study the flowfields in the laser chamber and the loss of the total pressure in several types of nozzles. the answer shows that reducing the length of the nozzles and the high of the throats in the nozzles can reducing the loss of the total pressure. and the answer also shows that the small nozzles with helium injected in the base region are good for laser chamber pressure recovery

    其次，本文利用cfd技術模擬了光腔流場，研究了幾種噴管的總壓損失特性。研究結果表明，對于平面對稱噴管，減小噴管長度，增加喉道高度有利於減少總壓的損失。用cfd技術對光腔段的模擬表明，採用小尺寸噴管，並且在基區大量注入氦氣有利於激光器壓力恢復。
  3. Inhalation of helium in excessive amounts can cause dizziness, nausea, vomiting, loss of consciousness and death

    過量吸入氬會導致眩暈、惡心、嘔吐、失去知覺和死亡。
