In the discrete process the mostly used method, the control volume method, is used. in the study of gas - particle flows numerical simulation, the gemchip arithmetic is often adopted. but it cannot be used directly in the investigation of clean room because of the low volume occupancy ( its volume fraction orde r is 10 - 10 below )
採用控制體積法對氣粒多相流的控制方程進行離散,在gemchip演算法基礎上,由於室內懸浮顆粒的體積分數數量級在10 ~ ( - 10 )以下,無法直接求解,在研究中通過直接求解顆粒數密度,不直接求解顆粒的體積分數對離散方程進行了求解。Designed so that all particles collected, regardless of physical size, shape, or density, are aerodynamically sized and can be directly related to human lung deposition
之所以這么設計,是因為所有被採集的微粒(不管體積大小、形狀和密度怎麼不同)都按照空氣動力學原理分級。這種分級,直接對應于微粒在人體肺部的沉積情況。Although sdh transmission is being widely applied in the core network, its tdm - based nature implies some weaknesses, such as large bandwidth granularity and inflexible bandwidth allocation, making it not suited to the access network where users are in great number and bandwidth demand is unpredictable. so the application of sdh in the access network is somewhat limited
雖然sdh傳輸技術正在廣泛地應用於核心級網路中,但是因為它採用時分復用的機制,具有帶寬的顆粒度太大,帶寬分配不靈活,不適合於接入網中用戶數量多、帶寬需求不確定等特點,所以sdh技術在接入網中的應用受到一定的限制。
