Let us consider the implication of the electrostatic theorem for chemical bonding in diatomic molecules.

让我们讨论双原子分子化学成键所蕴含的静电定理。

The relation between difference equation and differential equation is studied by analyzing the mechanism in building grey models, and a "bridge" is set up between difference equation and differential equation by sampling theorem and state transition matrix.

通过对灰色系统模型建模机理进行深入剖析，利用采样定理和状态转移矩阵在差分方程和微分方程之间架起一座桥梁，通过算例仿真实验证明了该算法的有效性。

Theorem 2 If has continuous partial derivatives at , then is differentiable at .

定理2如果函数在点的偏导数连续，则函数在该点可微分。

" In mathematics , two theorems, one associated with differential calculus and one with integral calculus."

数学中的两个定理。分别与微分学和积分学相关。

Physics majors learn the differential and integral calculus in the style of Cauchy and Weierstrass, with ε–δ definitions of continuity and differentiability.

这个定理还是非常有用的，下面就来演示一下。证明存在a，b两个无理数，使 a b 为有理数。是无理数，现在考察数X

In mathematics, Chinese scholars have achieved important results in fields such as number theory, theorem-proving by computer, differential geometry, topology, complex analysis, probability and mathematical statistics, PDE, functional analysis, numerical analysis and control theory and so on.

在数学方面，据我所知，中国数学家在诸如数论、定理机器证明、微分几何、拓扑学、复分析、概率论与数理统计、偏微分方程、泛函分析、数值分析和控制论等领域里也都取得了具有国际水平的成果。

Differential Calculus: limits and continuity; derivatives; techniques of differentiation; mean value theorem; higher derivatives; maxima and minima; curve sketching.

微分学：极限与续性、导、微分的方法、值定理、阶导数、值、绘曲线。

The π theorem for dimension analysis is complemented and consummated by themathematical methods on the basis of basic concept and means.

同时，本文对因次分析π定理有关在燃烧学中应用问题，作了简单的论述。

Theorem Let be differentiable at. Then has a directional derivative at in any direction and

定理 如果函数在点可微分，那么函数在该点沿任一方向的方向导数存在，且有

In 1976 Jorgensen established a fundamental theorem of Mobiusgroup in plane---criterion of discreteness.

Jorfensen在1976年建立了Mobius群的基本定理——离散性准则。

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。
