The classical elastic theory is precisely based on the Hooke's law, and issuitable to the depicting and describing of seismic wave propagation in the elasticmedia. But either from the experimental results of testing on the core, or from thepractical results of exploration and exploitation in the oilfield, the subsurface mediumshows more or less the non-elastic characteristics, namely viscoelastic behavior.

经典的弹性理论是建立在精确遵守虎克定律的基础之上的，弹性波动理论适用于对弹性介质中传播的地震波的刻画和描述，但是无论是对地下岩芯的实验室测试，还是油田的勘探开发实践，都已经证实地下介质或多或少地表现出非完全弹性，即粘弹性行为。

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。
