非线性法向变形节理对弹性纵波传播的影响 - In the self - calibration scheme , the thesis emphasizes the accuracy of camera intrinsic and extrinsic parameters . we presents an accurate f method based on corresponding point adjustment . the method adjusts coresponding points according to the fixedness of projective transformed cross ratio , then calculates f matrix accurately through linear and non - linear methods . when computing intrinsic parameter , a matrix , we simplify the step , and stress on the two important parameters of a . the result will be getten through solving kruppa equation based on svd decomposition . in order to compute extrinsic parameters , we use linear method to get initial r and t , then apply non - linear method to accurate them
提出了基于匹配点调整的f求精方法，先根据摄影交比不见性对手工选择的匹配点进行调整，再用线性、非线性结合的方法求精f矩阵；在计算内部参数a中，进行了一定的简化，把重心放在a中重要的两个参数上，用svd分解法计算kruppa方程；在计算外部参数时，首先用线性法求解r 、 t ，然后再用非线性法迭代求精。 - By using the multi - linearity regression model and the non - linearity logit model on the 123 listed companies of china in 2002 respectively , this paper also documents : after controlling the firm characteristics variables , the corporate governance variable increases the explanation power of the multi - linearity equation and it is positively related to enterprise credit significantly ; in the non - linearity logit model , we find that corporate governance has different effects on the companies that own dissimilar credit ratings , the improvement of corporate governance will powerfully upgrade the enterprise credit especially when the company owns a lower credit rating
在实证方面,本文运用多元线性回归法与logit非线性法对我国2002年123家上市公司进行了实证研究:在多元线性回归法中,在控制了影响企业信用的企业属性变量的基础方程中加入公司治理变量,发现公司治理变量的加入有助于加大方程的解释力度,并且两者在统计意义上显著正相关,说明良好的公司治理能在一定程度上提升上市公司的信用水平;在logit非线性方程中,我们发现企业信用水平不同时,公司治理对上市公司企业信用的影响是不同的,尤其是当企业信用水平较低时,公司治理的改善能在较大程度上提高上市公司的企业信用。
