low flow oxygen 中文意思是什麼
low flow oxygen
解釋
低流量氧氣-
The abnormal hemoglobin ss is prone to crystallization when oxygen tension is low, and the rbc ' s change shape to long, thin sickle forms that sludge in capillaries, further decreasing blood flow and oxygen tension
當氧分壓低時，異常的血紅蛋白ss有結晶的傾向，並且rbc變長呈薄的鐮刀樣形狀淤積在毛細血管中，進一步降低血液流動性和氧分壓。 -
In this paper, a three - dimensional ( 3d ) program for the three - dimensional reactive flow fields of complicated geometric nozzle, which governed by the compressible full navier - stokes equations with realizable k - s turbulent model, has been upbuilt by using full implicit couple arithmetic and fvm ( finite volume method ) based on understanding and assimilation of a two - dimensional program group of cr ( chamber - radon ). the new program fulfils the urgent need of numerical tools for simulating three - dimensional reactive flow - fields of hylte ( hypersonic low temperature ) and other latest nozzles, for which cr is out of action in simulation, and can be applied to simulate other chemical laser system, such as chemical oxygen iodine laser ( coil ), overtone fluoride hydrogen, all - gas iodine laser, and so on. furthermore, some related topics about nozzles design and engineer ing also have been discussed
本文在二維cr （ chamber ? radon ）程序研究的基礎上，採用有限體積方法和完全隱式的耦合演算法，通過求解帶realizablek -兩方程湍流模型的多組分、有反應的三維完全納維埃?斯托克斯（ n ? s ）控制方程，建立了一套能夠對復雜形狀的三維噴管和光腔進行數值模擬的三維程序，解決了連續波df hf化學激光器增益發生器設計缺乏三維數值模擬工具的問題，並用該工具解決了cr程序無法實現的hylte等復雜三維噴管流場的理論模擬問題。 -
Because the intertidal main channel of the shing mun river suffers from a very weak flow, pollutants have tended to build up in the sediment, leading to low levels of dissolved oxygen
城門河主河道的潮汐水流緩慢，污染物容易沉積在河床淤泥里，引致溶解氧水平下降，河水散發出惡臭。
