必要条件

This colored background of STN is illcome for people who accustom to black-white display. And from the conditions at present, black-white display is necessary condition to get colored display by insetting filter film.

STN的这种彩色背景，不受习惯于TN黑白显示的用户的欢迎；而且从目前的生产过程和生产条件来看，黑白显示是利用嵌镶滤色片作为获得彩色显示的必要条件。

We establish a relation between μ and the stucture of the group G, and obtain the lower bound of the ratio by the mininal prime divisor of the order and commutator of the group G, and give a necessary and sufficient condition under which this lower bound is attained.

第一部分，记有限群G的阶与不可约特征标个数的比值为μ，我们研究了一般的非交换有限群G的结构和μ之间的关系，通过群G的阶的最小素因子和换位子群G′的最小素因子得到了μ的一个下界，同时给出了达到下界的一个充分必要条件。

In the six chapter, we use the methods of reproducing kernel and Carleson measure charactering the pointwise multipliers on the Hardy space, Bergman space on the polydiscs, we also obtain a necessary condition for a composition operator to be a compact operator, and a addition result on the range of composition operator on the Hardy space.

在第六章中，我们利用再生核与Carl e Son测度刻画了多圆Hardy空间到Bergman空间，以及Bergman空间到Bergman空间的点乘子，得到Hardy空间与Bergman空间上复合算子为紧的一个必要条件，以及在Hardy空间上关于复合算子值域的一个结果。

By using of the comparison theorem and some results, some sufficient and necessary conditions are derived for permanence of the periodic system and non-permanence of predators.

If a PDE pass Painlev test, it will satisfy the essential condition of completely integrable; otherwise, the PDE is not completely integrable.

Weiss、Tabor和Carnevale提出的WTC算法给出了检验一个偏微分方程是否完全可积的必要条件-检验一个方程是否具有Painlev 性质。

The soundness and completeness theorem of this method were proved at last. This part consists of the following points: 1. The properties of the indecomposable extremely simple form of LP were discussed, the theorem shown that every logical formula of LP was equals of a generalized conjunction normal form. 2. The method for judging a logical formula is a indecomposable extremely simple form or not was discussed, the necessary and sufficient conditions of a logical formula with not more than three implicative connective being a indecomposable extremely simple form was given. 3. The α-resolution fields of the indecomposable extremely simple form of LP were discussed, some elementary results were obtained. 4. The automated reasoning method based on the resolution principle of classical logic was discussed, the author given a method to describe the set of clauses by using a matrix, and translated the resolution of two clauses to column operations of this matrix.

二、关于格值命题逻辑系统LP中α-自动推理方法的研究 1、对LP中不可分极简式的性质进行了研究，证明了LP中任何一个格值逻辑公式等值于一个广义合取范式； 2、对LP中不可分极简式的判定方法进行了研究，讨论了含有不超过3个蕴涵运算的格值逻辑式为不可分极简式的充分必要条件； 3、对LP中不可分极简式的α-归结域进行了研究，得到了一些基本结果； 4、对经典逻辑中基于归结原理的自动推理方法进行了研究，给出了用符号矩阵表示子句集合的一种方法，把不同的归结过程转换成矩阵的列变换。

An sufficient and necessary condition on generalized Nevanlinna counting functions of the inducing maps is shown to characterize the collective compactness of composition operator sequence.

我们用诱导映射的Nevanlinna计数函数给出了Hardy空间与加权Bergman空间之间的复合算子序列为总体紧算子序列的一个充分必要条件。

It is not even like Russian, but we have become too used to setting up comprehensibility as a necessary requirement of poetic language.

它甚至不是像俄罗斯，但我们已变得太用于设立诗意的语言理解性，作为一个必要条件。

The second section focuses on discussing the inherent relationship between the system of right to know and the construction of socialist political civilization. This section points out that: it is the precedent condition for promoting and assuring civil participation as well as for realizing and assuring democracy to keep information open and satisfy civil right to know; assuring the right to know is the essence of the ideology of supremacy in citizen and the important motive for promoting the formulation of our constitutional state; assuring civil right to know plays a crucial role in improving the credit of government and realizing the government management of standard and service; disclosure of government information is benefit to set a mechanism of anti-corruption and control, and to integrate the interest between government and the civil in order to realize the public interest; installation of the system of right to know is also the prerequisite to assure our social self-government of basic level.

第二部分重点论述了知情制度与社会主义政治文明建设的关系，指出：信息公开，满足公民的知情权，是促使和保证公民参与的先决条件，是实现民主与保障民主的根本前提：保障知情权是主权在民理念的必然要素，保障公民的知情权是宪政的价值目标之一，因而知情权的人权确认是推动我国民主宪政建设的重要动力；确认和保障公众的知情权是提高政府的信用，实现规范化、服务性的政府管理的关键所在：政府信息公开有助于反腐机制和监督机制的建设，政府与民众的利益整合，以促进公共利益的实现；建立知情制度确保公民知情权是保障社会基层自治得到切实的落实和良性运转的必要条件。
