In this note, we show that for any two matrices $A$ and $B$ over a generalized quaternion algebra defined on an arbitrary field ${\bf F}$ of characteristic not equal to two, if $A$ and $B$ are similar and the main diagonal elements of $A$ and $B$ are in $\bf F$, then their traces are equal.

本文对于特征不是2的任意域${\bf F}$上定义的广义四元数代数上的两个矩阵$A$和$B$，给出如果$A$和$B$相似并且它们的主对角线上的元素在${\bf F}$中，那么它们的迹相等。

Firstly, we study the normality of a family of meromorphic functions concerning differential polynomial and shared values and prove the following Theorem 23.5 Let F be a family of m...

证明了 定理 2.3.5设F为Δ上亚纯函数，k、n、q∈N，P=ω~q+α_(q-1)ω~(q-1)+…+α_1ω是多项式，并且设Hf，f~1，…，f~(k是不含常数项的多项式，a、b为两个判别的有穷复数，并且b≠0，c是非零有穷复数。

In here we study k-fault broadcasting graph in f mode, and give an algorithm to decide the least time in the minimal k-fault f-broadcasting graph. All factors are studied qualitatively.

在这里，我们讨论了f模式下的k容错广播图问题，给出了确定极小k容错f广播图中广播时间的算法，定性分析了各种影响因素的作用效果。

An n×n sign pattern A is a spectrally arbitrary pattern if for any given real monic polynomial f of degree n, there is a real matrix B∈Q and B has characteristic polynomial f.

设A为n阶符号模式矩阵，若对任意给定的一个n次首1实系数多项式f，都存在一个实矩阵B∈Q，使得B的特征多项式为f，则称A为谱任意符号模式。

Thirdly,we define a equivalence relation Rin the topology space X by the fibrewise function f ,and then we get the fibrewise quotient space X / R,we call it the fibrewise decomposition space of X .And last we discuss the relation between f and the natural mapping.

其三是，通过一个纤维映射f ： X→Y，在B上的纤维拓扑空间X中定义了一个等价关系R，得到X的纤维商空间X / R，称其为X的分解空间，最后也讨论了f与自然投射的关系。

Newton's second law formula: F = ma (F is force, m is mass, a for acceleration) and so on.

牛顿第二定律计算公式：F=ma（F为合力，m为质量，a为加速度）等。

Another important factor to consider is that compilers without partial template specialization or function template partial ordering support cannot handle the first form when f is a function object, and in most cases will not handle the second form when f is a function or a member function pointer.

还有另外一个重要因素，某些编译器不支持模板部分特化或者函数模板局部重排，所以当 f 是一个函数对象，或者 f 是一个函数指针或成员函数指针时，编译器无法处理。
