In an attempt to measure sf6 gas concentration in air , a new technology to determine gas concentration in a binary gas mixture is investigated 將超聲相關檢測技術應用于課題組承接的人本電器公司“ sf _ 6氣體濃度超標報警器研制”項目中,提出了一種實現超聲檢測微量二元混合氣體濃度的方法。
For membrane contactor process , the binary gas mixture diffusion through the pore channel should be considered as a transition diffusion of the absorbed momentum a through the stagnant momentum b . and the process would consist three steps : transition diffusion through the pore channel , stephen diffusion in the pore edge , and the pore interaction in the membrane surface 對于孔形狀為近似橢圓形的聚丙烯微孔膜,在研究擴散問題時,其等效孔徑可采用葉孔擴散問題中的孔形狀校正公式來計算。在膜接觸器中,氣體通過微孔膜的擴散機理為過渡擴散,其擴散過程包括通過孔道主體的過渡擴散、微孔膜出口處孔道邊緣的stephen擴散以及孔之間的相互作用。
