微地震事件的距离、能量、频数的一到四阶差分均能够显示微地震事件的变化规律，根据未失稳岩体微震事件距离、频数、能量差分变化规律，能够准确地利用微震监测技术预报岩体破裂，这对于采用微地震监测技术解决矿山井下岩体破坏失稳预报具有重要指导意义。

Lastly, a common rock,festively painted, can make a handypaperweight or doorstop, but this isnot recommended: you generallydon't want to give your loved oneanything that can be used to inflictserious bodily damage, especiallyafter they find out you got them apaperweight or doorstop.

一小块泥土也可以变成一个烟灰缸。你还不需要去打扮它，谁管那一堆脏兮兮的烟灰和烟屁股下面盖的是什么。最后，一块小石头。涂上节日的色彩，可以变成一个镇纸或者门阶。不过这个可不推荐。我不希望你给你爱的人一个危险的武器。

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.
