- 但从近几年发表的相关傅氏算法的文献来看，很多文章中关于信号相量的实部和虚部表达式有错误。
However, as to the expressions of the real or image parts of the phasor, there are many problems in the relevant documents published in recent years. - 这里通过详细的数学推导，给出了在不同数学模型下信号相量实部和虚部的具体表达式，并讨论了各种错误在微机保护应用中带来的问题。
After detailed analysis, the correct expressions are formulated and what the false expressions will bring about to the microcomputer protection is discussed. - 文摘:利用线性化方法，研究了一类非线性广义系统的可稳定问题.同时，利用中心流形定理，讨论了具有零实部特征值的临界情形的局部镇定问题.
Abstract: In this paper,we use the way of linearization to discuss the stabilization of a class of nonlinear generalized systems,and by use of the centre manifold we invesitigate controllability of critical index case of it.
