方阵

In this paper, we shall apply this concept to the ring of linear operators on Banach space X and prove that if a linear operator T on a Banach space X is defined in all of X and has finite descent and ascent then there is a Drazin inverse T~D satisfying TT~DT~k=T~k, T~DTT~D= T~D, and T~DT=TT~D for some nonegative integer k.

以后又对方阵的Drazin逆作了深入的研究。它的一些性质可以参阅。同时对它的应用也作了许多研究，例如可以把Drazin逆的概念应用到Markov过程、线性微分方程组、差分方程组和最优控制等方面。

But as the programs went on ,we learnt to walk the parade step and the route step which you need physical coordination ,or you'll look strange when you ara walking ,not very bad except not in tune with others walking around you And we were going to take part in review before the general ,however only 50%of us could have the chance to attend it as a square matrix ,the others will only be the spectators ,to tell the truth I was almost one of the spectators ,but as a guy who lack of compatibility 'cause my muscles were too nervous which made the drillmasters hesitate ,my drillmaster told the other one that that guy was the most hardworking one .

但是随着训练的进行，我们又学习了走便步和正步，这都需要身体的协调性，否则你会看起来有一点奇怪，不能算错，就是和周围的人不协调，而我们要去参加阅兵式接受首长的检验，然而只有一半的人可以作为一个方阵参加，其他的人就只能作为观众了，说实在的我几乎已经是观众中的一个了，但是作为一个所谓的身体不协调者，主要是因为我的肌肉太过于紧张导致的，我让教官们感觉到很犹豫不决，但是我的教官对另外一个说，这个孩子训练是最刻苦的，对方说，是的，我知道，你说呢？

讨论了对于退化矩阵E不是方阵情形的一般退化中立型微分系统的解，基于退化的常微分系统解的存在性条件，通过定义可解阵对和基础解以及利用拉普拉斯变换，给出了一般退化中立型微分系统解的存在性条件以及通解表达式。

As a major nineteenth century English novelist, Thomas Hardy occupies an unusual and prominent position in the age of literary transition from realism to modernism His structure of narration illustrating itself in "square dance","coincidence"and symbol of the four seasons in his novels,could be regarded as his great invention, a new writing approach which has enriched the writing style of novel The unusual structure of narration has endowed Hardy 's novels with a special charm and distinguish...

英国 1 9世纪小说家托马斯？哈代生活于小说创作的现实主义和现代主义交界时期，他以独特的创作手法在英国文坛上赢得了一席重要的地位。叙事结构可谓是他的一大独创，为小说创作提供了崭新的创作手法。这种结构具体体现在"方阵舞"的阵型、"巧合"的运用和四季的象征中，赋予了哈代的小说一种独特的魅力，也使他迥异于 1 9世纪英国其他的小说家。
