In chapter two , psr ( point spread response ) h ( t , x ; r0 ) is adopted to depict the model of sas system . exact transfer function is also given . time domain algorithm , range - doppler algorithm and wave number domain algorithm are being discussed and compared on this foundation 在此基础上,分别讨论时域算法、距离? ?多普勒算法、波数域算法并对其进行了比较,并对波数域算法的并行性做了初步研究。
In mfi , the thesis uses the bottom reflection phase shift as the cost function and the modal wave number as input data . also , it makes errors analysis by the statistical distribution between data errors and parameter errors . there are some new ideas in it 论文在使用匹配场反演方法反演海底参数中以海底反射相移曲线作为代价函数,模式波数作为输入数据,同时利用统计分布进行误差分析,具有一定的新意。
Given dynamic stress concentration factor around the interface circular lining . some examples and numerical results and illustrated , the influence of wave number , incident wave angle and combination of different medium parameters upon dynamic stress concentration factor are discussed 针对具体算例给出数据结果讨论了不同波数条件、不同入射角作用、不同的材料常数组合对界面衬砌散射波远场位移模式和散射截面的影响。
The results indicated that when the concentration of ge - doped was lower than lwt % , the ftir spectroscopy was nearly the same as that of czsi , but with the concentration of ge - doped increasing , in the spectroscopes of the lower wave number of near 710 cm - 1 , there appeared a new peak 利用ftir法测得了不同锗浓度单晶中的氧碳含量,并对其谱图进行了研究,得出:在谱图的低波数端随锗浓度的提高( 710cm ~ ( - 1 )附近)出现了新的谱峰。
From the resonant frequence can calculate the wave number k 0 , and we can get the r which correspond to the resonant frequence through optimize the unknown r , then we can get the result . the image part of the complex permittivity can get from the change of quality factor of the resonant cavity 由实验所测得的介质加载后的谐振频率可计算出谐振时的波数k0 ,这样就可以通过优化r的方法来寻找满足谐振频率的r 0 ,从而可以测得介质的介电常数。
