Then,the cosine value of central angle between the spacecraft and the descending node is solved by using cosine theorem of spherical geometry to avoid the cumbersome solving process by judging the flight direction of a satellite and the latitude of sub-satellite point in an original calculation model of image motion speeds.

通过球面几何的余弦定理直接求解航天器与降交点相对地心夹角的余弦值，避开了原像移速度计算模型中通过判断卫星飞行方向和星下点纬度来求解航天器与降交点相对地心夹角余弦值这一过程。

Discrete Cosine Transform has become one of the widely used transform techniques in digital signal processing.

The Coase theorem is the proposition that if private parties can bargain without cost over the allocation of resources, they can solve the problem of externalities on their own.

科斯定理的命题，如果私人各方可以讨价还价的成本超过了资源配置，他们可以解决的问题，外部对自己的。

The maximum principle of the optimal control for the stochastic systems described by Zakaj stochastic partial sifferential equationis proved by approximately minimum point theorem of E. Ekeland. The convexity and compactness of the set of control values is not assumed, and it is not necessary for the maximum principle about differentiability in control variables included in drift term of the stoch astic system and the integrand in index functional, and costate process satisfies the stochastic partial ...

在不假便定控制变量取值的集合是凸的和紧的，不要求随机系统的漂移项和指标泛函的被积函数关于控制变量具有可微性的情况下，用E，Ekeland的近似极小点定理证明了Zakai随机偏微分方程描述的随机系统的最优控制的最大值原理，和用很简洁的方法证明了协态过程满足一个随机偏微分方程。

According to the author's Cotangent relations theorem, bearings-only target tracking with linear motion is achieved.

根据所提出的余切关系定理，实现了纯方位观测的直线运动目标跟踪。

A new cotangent theorem is deduced to solve the nonlinearity for bearing-only measurement.

通过新提出的余切关系定理，解决了单站纯方位观测的非线性问题。

Equation (1) is Gauss theorem, it is can be derived from Coulomb's law, expressed the electric field diverges outward from the charge, equation (2) expression does not exist a separate poles.

方程式（1）就是高斯定理，它可以从库仑定律推导出来，表述电场从电荷向外发散，方程式（2）表述不存在单独的磁极。

This statement is Coulomb's Law in its conceptual form.

这句话是以概念形式叙述的库伦定理。

The aim of this paper is to study the countability on I-fuzzy topological spaces.

本文主要是研究I-fuzzy拓扑空间中的可数性，提出I-fuzzy第一可数性、I-fuzzy第二可数性、I-fuzzy可分性、I-fuzzy Lindelf性等几种可数性的概念，界定了它们的特征性质，给出了它们之间的关系，还在第一可数I-fuzzy拓扑空间中用多值序列收敛对映射连续性进行刻画，更为重要的是得到了I-fuzzy拓扑空间中的I-fuzzy Lindelf定理。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
