线性

We first got the PML equations by making the radius complex, and then proved that the sesquilinear form in the weak formulation of the PML problem satisfies the Grding inequality under the hypothesis of the absorption factor, and further could prove the existence and uniqueness of the solutions of the PML problem, finally, we gave the numerical experiments which show that this method is feasible to a certain extent.

首先通过复化极径得到PML方程，然后在关于吸收参数的假设下，证明了PML问题变分形式中的半双线性形式满足Grding不等式，进而证明了PML问题解的存在惟一性，并给出了数值实验。实验结果表明，该方法有一定的可行性。

Vector spaces are a central theme in modern mathematics ; thus, linear algebra is widely used in both abstract algebra and functional analysis .

向量空间的一个中心主题在现代数学，因此，线性代数被广泛使用在抽象代数和功能分析。

Vector is the new high school textbooks and the new one of the important contents, it is rich in physical background, it is the object of study algebra, and geometry is the object of study is set,"the number of Form" in a mathematical concept of an abstract algebra, linear algebra and functional analysis of the basic mathematical model.

向量是高中新教材中新增加的重要内容之一，它有着丰富的物理背景，它既是代数研究的对象，又是几何研究的对象，是集"数、形"于一身的数学概念，是抽象代数、线性代数、泛函分析中的基本数学模型。

In addition to calculus with linear algebra, I had two semesters of mathematical analysis, partial differential equations, abstract algebra was also a senior this semester in the measurement theory.

除了微积分跟线性代数，我还上了两个学期的数学分析，偏微分方程，抽象代数还有在大四这个学期上的测量理论。

The author is aimed at the problem with linear too abstract algebra, talk about oneself to have the method of a few kinds of teaching of incorporate, visualize in education process, in order to offer colleague reference.

笔者针对线性代数过于抽象的新问题，谈谈自己在教学过程中进行具体化、形象化的几种教学方法，以供同仁参考。

I am a professor of the Department of Applied Mathematics at Xiamen University, a doctoral supervisor, and also the mentor of Mr. Ben Niu in the course Linear Algebra and the course Abstract Algebra. Therefore I have good knowledge of his academic capabilities and potential, so to speak...

我是厦门大学数学系教授、博士生导师，也是牛犇线性代数和抽象代数的授课老师，可以说我对他的学习能力和发展潜力是比较了解的，听说他正申请攻读贵校的硕士研究生课程，我当然全力支持。。。

Sequences of 28S rDNA across Acari, though with variable region, were not randomly distributed, with the expansion segments being more variable than the core regions and with an increasing sequence divergence with taxonomic distances.

散布图显示，转换取代与颠换取代有类似的线性变化；支序分析及群聚分析的亲缘关系显示，同科及同属内的成员都群聚的很好，全爪蟎属与小爪蟎属的亲缘关系近，与叶蟎属较近的是岩蟎属。28S rDNA的序列特性显示，其核心序列适合分析较高阶的蟎蜱亲缘，而展延区则可应用於低阶的分析。

As in the case of linear motion, Eq.(1) holds for any type of angular motion while the other four are true only for uniformly accelerated angular motion.

如在关于线性运动的情况一样，方程(1)适用于任何类型的角运动，而另外四个方程只适用于匀加速角运动。

The results are presented and compared with the available results of other authors, which shows satisfying agreement. And a submerged body beneath the free surface in accelerated motion is considered; the numerical results of instant wave resistance and free surface elevation are presented and discussed.

对非定常线性兴波问题的求解，第5章作为算法的验证，从较简单的近自由面运动潜体的非定常兴波问题入手，首先对无限水深近自由面潜体突然加速和渐近加速的非定常兴波问题作了计算，给出了非定常兴波波形和非定常兴波阻力随时间的变化曲线，计算结果与其它文献给出的结果进行了比较，其吻合程度令人满意。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
