Secondly , this paper illustrated the nonlinear phase dynamic theory of the aia array and the application of it to power - combining and beam - scaning technique . according to these theories , the coupling parameter of nearest neighbors was found by experiment , then the two - element and three - element aia array were designed , and the result of measurement was in agree with that of the nonlinear phase dynamic theory , and the beam - scaning of two - element array was realized by tuning the free oscillation frequency of the elements 其次，本文讨论了有源集成天线阵列的非线性相位动态理论以及它在功率合成和波束扫描方面的应用，包括同步工作条件、稳定条件和相位动态方程等，通过实验确定了阵列中相邻单元间耦合参数，并将之运用于有源集成天线二元阵和三元阵的设计，实验结果与理论结果吻合较好。
And then , the thesis import a thrice - polynomial technology to depict the yield curve of shanghai stork exchange market and gained the yield curve chart . under one factor model hypothesis , deduce the bond pricing formulae . based on 1945 data of buy - back rate in banking market , the thesis use ols and gmm estimation technologies to estimate the parameters of vasicek model , cir model , and ckls model , and verify which model can explain the china market ’ s short rate ’ s wave 然后,从实证的角度,用三次多项式来拟合上交所国债收益率曲线,并得出收益率曲线图,在单因素模型推导了动态理论期限结构下的债券定价公式,并以1945个中国银行间债券市场7天回购利率数据作为短期利率的代表,验证vasicek模型、 cir模型与ckls模型是否适用中国短期利率的波动行为,估计出三个模型的参数。
