The specific thread of this paper is: The first chapter introduces briefly basic theory of performance management, including the basic concept, theoretical base, and system of performance management.

本文阐述的具体思路是：第一章，简述绩效管理的基本理论。包括绩效管理的基本概念、绩效管理的理论基础和绩效管理的体系构架。

In the first section,the existence of solution for a class of non-linear systems with three -point boundary problem is obtained by applying the differential inequality theory .

在第一部分中，我们应用微分不等式理论证明了一类非线性系统三点边值问题解的存在性；在第二部分中，运用微分不等式理论研究了一类带有转向点的拟线性奇摄动边值问题的非单调内层解；在第三部分中，利用对角化方法研究了一类向量二点或者三点边值问题解的存在性，并获得解及它的一、二阶导数的渐近估计。

At the first party congress in 1924, which included non-KMT delegates such as members of the CCP, they adopted Sun's political theory, which included the Three Principles of the People - nationalism, democracy, and people's livelihood.

在第一次全国代表大会于1924年，其中包括非国民党的代表，如成员的中共，他们通过了Sun的政治理论，其中包括三民主义-民族主义，民主和民生。

A novel method that makes use of rough set theory to detect moving small target with low SNR in infrared image sequences is presented. First, Morphology Top-Hat operator is used to separate candidate small targets and extract their attributes.

提出了利用粗糙集理论处理不完整信息的能力对红外弱小目标的运动轨迹进行辨识的检测方法。

It is pointed out for the first time, that if in the Chern-Simons field theory the vortex lines are knots, the Chern-Simons action itself is a topological invariant; a step further, this action is just the total sum of all the self-linking and linking numbers of knot family.

文中首次指出，当陈-Simons场论中的涡旋线是纽结时，陈-Simons作用量本身是一个拓扑不变量，并进而指出这一作用量恰是纽结族的所有Self-Linking数和Linking数之和。

Secondly,as an application ofφ-mapping topological current the-ory,the vortices in TDGL model have been studied.Some importantartificial hyperthesises in other theories have been changed into naturalresults ofφ-mapping topological current theory.The inner structureof vortices system in the TDGL model has been obtained in terms oforder parameter field.For the first time,the branch process of thevortex system in the TDGL model have been discussed.

其次，作为Ф-映射拓扑流理论的重要应用，本文研究了TDGL模型的vortex动力学，对过去该模型中的一些人为假设给予了合理而严格的理论基础，用序参数的Hopf指数和Srouwer度表征了拓扑荷，建立了该系统拓扑性质的新理论，并首次探讨了TDGL模型中的vortex的分岔过程。

This paper does not intend to Toynbee's philosophy of history to add, just borrow one of his "civilized type of" theory, derived "cultural type" of this concept and to apply this concept he outlined in the first 26 civil society 1 - Western society, and Analysis of Western cultural traditions and the status quo.

本文无意对汤因比的历史哲学作出补充，只是借用他的"文明类型"理论，引伸出"文化类型"这一概念，并把这一概念运用于他所列举的二十六个文明社会的第一个——西方社会，分析西方文化传统和现状。

This essay focuses on the first study, tracing the reception and study conditions of this theory in China.

本文就第一种类型进行研究，以期梳理该理论在我国的接受与研究状况。

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.

交际能力和语法的关系应该是目标与途径的关系。
