存在的性质

Jordan normal form in a complex domain existence and uniqueness of these two important properties, is a powerful tool for problem solving, use of these two properties can effectively streamline the difficulties to obtain the multiplier effect.

Jordan标准形在复数域中有存在性和唯一性这两个重要性质，是我们解题的有利工具，运用这两个性质能有效的简化问题的难度，以取得事半功倍的效果。

At first, based on the results of the field tests and studies, this paper indicates that there are two kinds of low frequency power oscillations on the weak tie line: one is caused by negative damping, and belongs to the free oscillation; the other is caused by periodic load disturbances and periodic adjustments, and belongs to the forced oscillation.

首先，本文根据现场试验和研究结果指出，互联系统的弱联络线上存在两类性质不同的低频功率振荡：一类是由负阻尼引起的，属于自由振荡；另一类是由于系统周期性负荷扰动或振荡调节等引起的，属于强迫振荡。

In usual crystalline materials, one finds an inverse relation between the two properties, as for many practical applications, simultaneous presence of both properties is desirable.

在普通的晶体材料中，人们会发现这两种性质之间的相反关系，但是对于许多实际应用来说，两种特性的同时存在才是人们所追求的。

The results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.

结果表明，长安南部黄土塬随着层位的降低，pH值有逐渐增大趋势，电导率和HCO(上标–下标 3)含量有逐渐减少的趋势；黄土地下水、冲积层地下水和酸性岩石地下水的化学成分存在明显差异，这与其理深、地层性质、溶滤与蒸发作用不同有关；长安南部少陵源黄土地下水元素含量较高，比呈酸性、元素含量低的翠华山泉水更适于饮用。

There have been a lot of studies on the effective properties of multiphase materials widely used in industry.

多相介质有极为广泛的应用，但是关于它的有效性质的已有各种方法都存在不同程度的问题，有的甚至在概念上含糊不清。

In chapter 2, by virtue of the properties of partially ordered F-type topological space, we establish some fixed point theorems of increasing mappings in this kind of space. At the same time, we investigate the existence of maximum fixed point and minimum fixed point of increasing mappings on an order interval.

第二章，利用半序F-型拓扑空间的基本性质，建立这类空间上单调增映射的不动点定理，研究其序区间上单调增映射的最大、最小不动点的存在性。

The various forms of polytheism that now flourish, or that have existed in the past, are the result of man's faulty attempts to interpret nature by the light of unaided reason.

各种形式的多神教，现在蓬勃发展，或者说过去存在，是由於人的错误试图解释性质的参照外援的原因。

Together with some basic knowledge of Linear Algebra, we prove that there exists a polynomial time algorithm for finding the shortest contractible cycle in an locally LEW-embedded graph. 3. By some results of Minor Theorem, we prove the crossing numbers of some circular graphs C(10,4), C(9,3), C(8,3) on the projective plane.

利用C.Thomassen在大边宽嵌入方面的工作，得到了局部大边宽嵌入图的一些性质，再利用线性代数的知识，证明了在局部大边宽条件下存在多项式时间算法可以找到一个图的最短可收缩圈。

There exists a projective relation between the direction number s of which linebundle and bundle of places are projective corresponding to each other.

发现并证明了把的异素对应中的一个重要性质，即在射影对应的线把和面把中，其对应元素的方向数之间存在着一一对应关系。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
