求翻译：我们知道,并不是对于每一个线性变换都有一组基，使它在这组基下的矩阵成为对角形.在适当选择的基下，一般的一个线性变换能化简成什么形状，是高等代数中的一个重要问题.并且无限维空间上的算子谱论，相当于把矩阵化为若尔当标准形.若尔当标准形对于算子谱论的研究具有重要的意义.本文主要介绍了若尔当标准形的背景，研究方法及一些应用.是什么意思？

We know that is not for every linear transformation has a set of groups , making it the matrix at the base of this group become diagonal . In properly selected base , generally a linear transformation can be simplified into what shape is advanced algebra

We knew that, is not all has group of bases regarding each linear substitution, causes it to become angular to under this group of base matrix. In under the suitable choice base, a general linear substitution can simplify any shape, is in an advanced algebra important question. And in the infinite U

We know, is not for each a linear transform are has a group base, makes it in this group base Xia of matrix became diagonal shaped. in appropriate select of base Xia, General of a linear transform can of Jane into what shape, is high algebra in the of a important problem. and unlimited dimension spa
