The problem of slow TPH degradation found to be related to the polar fractions accumulation. Increase of fungi community diversity was found helpful in decomposition of the polar fractions. The symbiotic environment between bacteria and fungi was beneficial to the 2nd –stage TPH biodegradation.
至於各组降解迟滞的问题则与污染物三成份中极性物质的累积有关，在累积过程中真菌类多样性的增加，有助於极性物质的去除，最后细菌类与真菌类共生的环境能使污染物产生第二阶段的降解反应，因此污染物能持续降解。

By applying these two tools,we mainly discuss the problems as follows:1 Perturbation identities for the generalized polar decomposition:By applying singular value decomposition, we study the perturbation bounds of the generalized polar decomposition under unitary invariant norms when A is perturbed by addition or multiplication,respectively and give our bounds in identities.2 A class of new unitary invariant metrics: This paper generalized a class of new unitarily invariant metrics and give the upper-bounds and lower-bounds by C-S decomposition.
利用这两个强有力的工具，本文主要讨论了如下问题：1 矩阵广义极分解的扰动等式：利用奇异值分解，本文分别讨论了加法扰动和乘法扰动下矩阵广义极分解在任意酉不变范数下的扰动界，并首次以恒等式的形式给出了酉极因子和半正定因子的扰动界。2 一类新的酉不变度量：本文推广了文[22] 中的结论，定义了一类新的酉不变度量。

IHT is make used of to proceed line edge fitting in the actual engineering. The auto-adaptable image edge detection method is applied to detect image edge in real project, and the region of image edge detected is limited within 1 pixel. IHT is also applied to fit line edge. Comparing with MHT, the result of IHT indicates its speed quick, the accuracy high, and anti-jamming-quality strong, exactly said that the accuracy of IHT fitted line is less than 0.1 pixel for polar distance and less than 0.01deg for polar angle.
自适应边缘检测方法被应用于检测实际工程的图像边缘，检测到的边缘区域在亚像素之内；修正的Hough 变换算法也被运用于相应工程的直线拟合，与传统的Hough算法相比，结果表明其速度更快、精度更高，抗干扰能力更强，其拟合直线的极径精度可达到0.1个像素，极角精度可达0.01度。
