1. 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，采用有限體積方法和完全隱式的耦合算法，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(shù)值模擬的三維程序，解決了連續(xù)波dfhf化學激光器增益發(fā)生器設計缺乏三維數(shù)值模擬工具的問題，并用該工具解決了cr程序無法實現(xiàn)的hylte等復雜三維噴管流場的理論模擬問題。
2. It's difficult to find oxygen iodine laser in a sentence. 用oxygen iodine laser造句挺難的
