In conclusion, by consideration of viscosity effect of material at propagating crack-tip, it is established in the paper the unified continuous singular crack-tip field in linear-hardening material under the condition of incompressibility. The plastic shock is eliminated that exists in non-viscosity solutions. What's more, the dynamic and quasi-static solutions are united together when the Mach number approaches zero.

总之，通过考虑扩展裂纹尖端材料的粘性效应，本文建立了幂硬化材料在不可压缩条件下扩展裂纹尖端的统一的连续奇异性场，消除了无粘性解中存在的塑性激波，在马赫数趋于零时动态解和准静态解得到了统一。

And in 1981, in "Raiders of the Lost Ark," that approach was so old-fashioned it looked new. In the 27 years since, practically every action filmmaker has tried to tap into the movie's quasi-mystical kinetic power: the pace had to be blindingly fast; the stunts insanely elaborate, the villainy extra-villainous; the hero's attitude blithe, insouciant, almost sociopathically cool.

1981年《法柜奇兵》的处理方式，就做得老派而历久弥新。27年来，实际上每一位动作片导演都尝试充分利用这部电影有点神秘的活动能量：速度必须快到令人眼花撩乱；特技动作必须疯狂复杂；为非作歹耍坏到不行；英雄的态度乐天、逍遥、酷到几乎反社会的程度。

There are millions of population migrations from the rural areas to the urban areas, but they are instable and quasi-urbanization.

虽然有数以千万计的的乡村—城市的流动人口，但不稳定，呈准城市化状态。

The finiteelements satisfied the integral condition are quasi-conforming element,generalized conforming element,and elements constructed by 2 set parametermethod,and they are equivalent in some sense,and all converge to constantstrain.

满足这种条件的有限元有拟协调元、广义协调元和双参数法构造的单元，在一定意义上它们是等价的，并都收敛到常应变。

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。
