An opportunity, however, presented itself: being required to work out from data supplied to him the ''défflement'' of a proposed fortress (an operation then only performed by a long arithmetical process), Monge, substituting for this a geometrical method, obtained the result so quickly that the commandant at first refused to receive it - the time necessary for the work had not been taken; but upon examination the value of the discovery was recognized, and the method was adopted.

但是一个机会出现了：蒙日需要根据数据计算一个设计中的要塞的枪炮布置（通常需要很长的算术过程来完成），他用了一个几何的方法来代替，如此迅速地得到了结果，以至于司令官一开始拒绝接受-因为一般完成工作所需的时间还没有过去；但是检查发现的价值被认可了，而且该方法被采纳了。

In the analysis of dynamics cutting angle, the following phenomenon is discovered first time: the minimize of dynamics clearance angle is not monotone decreasing with the vibration frequency , and appear peak value periodically, which exist is the disseparation region and approach the separation region.

在对振动钻削中切削刃上各点的动态角度的分析中，首次发现在振动钻削过程中动态后角的最小值不是随着频率或频转比的增大单调下降，而是周期性的出现波峰值，这些波峰值都出现在不分离区，而且是接近于分离区处，这是由振动钻削过程中的变速特性引起的。

The approach first chooses three continuous data points in turn when the data points in time series are scanned. According to the angle formed by these three data and the extreme value in monotone sequence, the method then records key points reflecting the sequences changing feature.

该算法在扫描数据的过程中利用单调序列中三个连续数据形成的夹角和非单调序列中的极值点，从序列中挑选反映趋势变化的关键点，实现时间序列的线性拟合。

The author thinks that human resources can maximize its value and function. At the same time, it can speed up the increment of physical capital. He defines it as"motile"and"positive"increment. 5. The author agrees that there is absolute deficiency in Chinese education investment.

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。
