With the discussion of extreme value problem of the multiple-valued function,and the popularizing of extreme value theory of the two-value function,This paper obtains differentiation rule about the extreme value of the multiple-value function,and illustrates the apllication of the theory with the example,providing proper guidance for the teaching of calculus.

文章讨论了多元函数的极值问题，并将二元函数的极值判定定理加以推广，得到关于多元函数极值的判定法则，并举例说明其应用，这对微积分的教学有一定的指导意义。

"If you want to succeed, double your failure rate."

成功的法则就是把犯错误的速度提高一倍。

Fall into a rut early Don't forget that part of the 3 times rule comes from properly practicing another rule of thumb - fall into a rut early.

别早早忘了成为车辙秋天3时间规则的部分适当地来自实践另一个经验法则－通往车辙的秋天。

An explicit mathematical representation of the exact boundary of a ball Bézier surface was given by recurring to the envelope theory of the family of bivariate surfaces in the classic differential geometry, as well as the spherical coordinates and the Cramer's rule.

根据经典微分几何中双参数曲面族的包络原理，运用球面参数坐标和Cramer法则，给出了球域Bézier曲面边界的精确数学显式表达式。

Works of nature are, they think, made worse and altogether feebler when wizened by the rules of art.

自然的鬼斧神工一经艺术法则的破坏，马上就会变得糟糕和脆弱不堪。

For example, basic tools from calculus such as Fermat theorem, Rolle theorem and the intermediate value theorem may not necessarily hold and fundamental concepts such as chain and product rules and certain smoothness properties all need to be modified.

例如，微积分中的基本工具诸如Fermat定理、Rolle定理以及介值定理不再成立，一些基本的概念诸如链式法则、乘积公式以及某些光滑性都需要做适当的修正。

Then, katie is on the basics that learns example, join him body model with temperament, found the clad law that suits again distinctly already, make media open-eyed, also got more filmgoer love.

于是，Katie在学习典范的基础上，结合自己身型和气质，找到了既独特又适合的穿衣法则，让媒体惊奇，也得到了更多影迷的喜爱。

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.
