1. radix 2 fft algorithms is analyzed, and fixed geometry configuration and blocking floating format of data is used to implement 256 points 12 bit complex numbers fft
   并在分析了基2fft算法的基礎(chǔ)上,采用固定幾何結(jié)構(gòu)和塊浮點數(shù)據(jù)格式,實現(xiàn)了256點12位復數(shù)點的fft運算。
2. the numerical results of the dispersion relation show some nonlinear effects : for a fixed geometry of a waveguid, beam parameters and plasma density, the increment of the modulation parameter may lead to a slight increment of the operating frequency, however, as the modulation parameter increases further, saturation may occur and the dispersion relations are hard to be separated, it is due to the overmodulation of the microwave power, this phenomenon itself belongs to the nonlinear effects
   對于一定的波導、電子注參量和等離子體密度值，等離子體調(diào)制系數(shù)的增加，使工作頻率略微升高。但是，隨著等離子體調(diào)制系數(shù)的進一步增加，色散曲線變得彼此之間不可分辨，可以認為是等離子體的過調(diào)制導致了柵的飽和。這一現(xiàn)象是非線性的，可見，等離子體柵和調(diào)制場中文摘要是非線性關(guān)系，等離子體柵是非線性j。
3. in this paper, maccormack explicit time-split scheme, baldwin-lomax algebraic turbulent model and two-steps hydrogen-air nonequilibrium chemical kinetics model are employed to simulate the 2-d flow fields in a fixed geometry scramjet combustor in different injecting way of fuel in different flight conditions . the results show, in the same entrance condition, the operating mode of scramjet combustor is influenced by the control of fuel
   本文采用maccormack顯式時間分裂法、b-l代數(shù)渦粘性湍流模型及氫-空氣兩步非平衡化學動力學反應模型，模擬了在不同的飛行馬赫數(shù)條件下，固定幾何的雙模態(tài)燃燒室在不同供油規(guī)律下的二維燃燒流場。
4. It's difficult to find fixed geometry in a sentence. 用fixed geometry造句挺難的
