In school they teach you the Chain Rule, and you can memorize the formula and apply it on exams, but how many students really know what it "means" So they're not going to be able to know to apply the formula when they run across a chain-rule problem in the wild.

在学校里他们教你链式法则，你也能回忆起他们并能运用在考试题上，但有多少学生能真正的了解他们到底意味着什么呢所以当他们遇到变种的链式问题时，他们就不懂得如何运用公式了。

Ula. The chain rule is just how to take the derivative of "chained" functions

易。链式法则仅仅是如何对链式函数求导的意思，函数 x 引用函数 g ，你要求导 xg

The formulas calculating higher derivatives of parametric functions and composite functions are given by the chain rule and the product formula for derivatives.

用函数的链式法则和乘积公式给出了参数函数和复合函数的高阶导数的计算公式。

Let's differerntiate both sides of with respect to x using the Chain Rule.

应用链式法则，方程两边对x求导。

The chain rule is just how to take the derivative of "chained"functions — meaning, function x calls function g, and you want the

Through analysis, I believe that university teachers from the ecological management of human resources out of the shackles of limiting factors to establish an environment for teacher development; according to niche theory, maintain a reasonable and orderly competition; follow the ecological chain rule, establish a rational human resource structure ; based on co-evolution theory, maintain the ecological vitality of teachers and other system aspects.

通过分析，笔者认为高校教师人力资源的生态管理要从摆脱限制因子的束缚，建立适合教师发展的环境；根据生态位原理，维持合理有序地竞争；遵循生态链法则，建立合理的人力资源结构；依据协同进化原理，保持教师系统生态活力等多个方面进行。

Then how to use limited Markov chain and Bayes' rule in DHCM to dynamically describe the evolution of enterprises' cooperative relationships, specifically evolution of cooperative relationships building and cooperative relationships selecting is analyzed. Finally, how to optimize related action sets in the model during the evolution is discussed.

模型首先对企业整体协作关系进行了一般性描述和形式化描述，之后利用有限马尔可夫链和贝叶斯法则对在面临新的市场需求的情况下企业之间是否建立协作关系以及建立何种协作关系进行了动态描述，并分析了在新的市场需求下，企业实体将如何选择最优的行动集。

The definition and stability criterion of resonant operating points in a CPT system have been described. A Poincarémapping model has been built up and its Jacobian matrix has been derived with the implicit function derivative rule and chain rule. Then the stability of the fixed points can be determined according to the eigenvalues of the the Jacobian matrix. It has been used to study an example push-pull CPT system with three resonant operating points.

文中给出了CPT系统中谐振点的定义及判断条件，建立了系统的庞加莱映射模型，并根据隐函数及复合函数求导法则，推导出了系统庞加莱映射周期不动点的雅可比矩阵，根据雅可比矩阵的特征值分布情况，即可判断各不动点的自治振荡稳定性。

Based on the chain rule techniques, AD seeks first or higher order derivatives of functions represented by a group of dependent program procedures and extended files, the so-called original model, through a number of code-to-code transformings under a series of differential rules.

基于链式求导法则的自动微分方法通过改写原程序模式代码，依赖机器自动构造不同的微分模式，来分析求解函数的一阶或高阶导数，即在一系列预定微分规则下对不同程序对象做从代码到代码的自动微分转换。

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。
