The justifiability for the court to enjoy the power of judicial review is not only because of the defeat in the legislative or administrative review,but determined by the features of judicial power.

法院的这种审查权是行政诉讼制度发挥功能的必要条件，没有这种审查权，法院对具体行政行为的合法性审查就无法落实。

The difference of survivin expression intensity was statistically significant (P.05). Conclusion: A suitable-expression of survivin in normal early gestation villi may be crucial for embryo karyokinesis and cell proliferation. An over-expression of survivin in GTDs may be an important role in their oncogenesis.

适度survivin是正确完成胚胎细胞有丝分裂和细胞增殖的必要条件，因survivin的过表达引起的细胞凋亡阻滞在妊娠滋养细胞疾病的发生发展过程中可能起重要作用。

Increasing the kilovolt peak or milliamperes used during scanning can reduce noise and improve scan quality, but this is not generally necessary to obtain diagnostic scans.

增加扫描时的管电压和电流能够减少噪声，改善图象质量，但是这不是获得诊断扫描图象的必要条件。

In this paper, we shall use both direct constructions and recursive constructions to prove that the necessary conditions for simple Kirkman frames of type t with index 4 are also sufficient.

本文通过直接构造和递推构造的方法证明了组型一致的(3， 4)单纯支架存在的必要条件也是充分的。

At first, we present a necessary condition for the existence of optimal linear state feedback control by means of Lagrange multiplier theorem.

首先利用Lagrange multiplier定理得到了存在最优线性状态反馈解的必要条件，而在加强的条件下也得到了最优控制存在的充分条件。

The necessary conditions for the optimal plastic design are obtained by means of the Lagrange multiplier method,and then the optimality conditions are derived.

数学上它表述为一个具有不等式约束的泛函极值问题，应用拉格朗日乘子法得到了最优塑性设计的一组必要条件，并由此导出了最优性条件。

S. dollars and the decline of the Cold War provided the economic and political environment for European countries to integrate. For encouraging the economic incentives, major European countries' ruling parties ended the policies of Keynesian School and constructed a relative convergence for a European-wide laissez-faire economic policy. However, the most important impetus for the building of the European Union is the less strengthened role of the European region in the global competitiveness. For yielding part of their sovereignties, EU countries can enlarge their capacity, and survive much stronger in a global World.

当然，促成欧洲联盟形成原因甚多，不过欧洲在全球化竞争中居明显劣势地位仍是欧洲整合再出发的最主要堆动力，本文指出各国政策汇合因素只能算是新区域整合的必要条件，仍非充分条件，最大因素仍应是欧洲各国为因应全球化桃战形成的新区域整合，也即籍助於让渡部分主权，欧盟各国因而更能扩大本身的职能，於此，两岸似亦应从中获得相当放示才是。

The biathlon consists of the shooting and langlauf. Our elite biathlon advance the sliding speed limitedly. It is necessary for them to shorten the shooting time and to improve the shoot straight.

冬季两项是由越野滑雪和射击两部分组成的特殊周期性项目，我国优秀冬季两项选手在滑行速度训练潜力的挖掘是有限的，所以缩短射击时间、提高射击命中率是提高选手成绩的必要条件。

If N is a nonempty subset of a left R module M, then N is a submodule of M if and only if the following conditions hold:(1) x+y is in N for any element x,y in N;(2) rx is in N for any r in the ring R, and any x in N.

假设 N 是左模的非空子集合，那么N 是子模的充分必要条件是，对N 中的任何两个元素x，y有

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
