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(diǎn)數(shù)據(jù)格式,實(shí)現(xiàn)了256點(diǎn)12位復(fù)數(shù)點(diǎn)的fft運(yùn)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(duì)于一定的波導(dǎo)、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(jìn)一步增加，色散曲線變得彼此之間不可分辨，可以認(rèn)為是等離子體的過(guò)調(diào)制導(dǎo)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(chǎng)中文摘要是非線性關(guān)系，等離子體柵是非線性j 。
