The interval sowing experiments showed that 291S was a photo-thermo-sensitive male sterile line, which showed part fertile under short-day and low-temperature conditions when autumn sowing, showed high sterile under long-day and high-temperature conditions when spring sowing. The self-multiplication ability and sterility of 291S can be improved through selection effectively. The pistillody of stamens of 291S could be induced under certain photoperiod and temperature condition.

分期播种试验表明，291S是一种光温敏雄性不育系，秋播短日低温条件下表现为部分可育，春播长日高温条件下表现为高度不育，其可繁性和不育性经选择可以得到有效改良。291S在一定的光温条件诱导下会出现雄蕊心皮化现象。

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。
