For the compressible materials, in order to satisfy the higher-order compatibility equation of the rate of deformation in the centered fan sector, which is a quite difficult problem unresolved in the previous studies, a particular term must be added to the expansions of the stress components in the regular logarithmic power series adopted by many researchers before. A higher-order near tip field with tangential velocity jump ahead of the crack tip is derived first, of which the dominant terms are the solution widely accepted.

对可压缩材料，本文首先采用非规则的对数幂级数渐近展开方法，克服了过去研究中存在的中心扇形区变形率协调方程的高次渐近式不能被满足的困难，并得到了一个切向速度在裂尖前方存在间断的高阶渐近解，该解的主项就是目前被广泛接受的关于可压缩材料的尖端场解。

Or on a Sunday afternoon,if I chanced to be at home, I heard the cronching of the snow made by the step of a long-headed farmer, who from far through the woods sought my house, to have a social "crack"; one of the few of his vocation who are "men on their farms"; who donned a frock instead of a professor's gown, and is as ready to extract the moral out of church or state as to haul a load of manure from his barn-yard.

他用慈祥的智力，拥抱了孩子、乞丐、疯子、学者，一切思想都兼容并包，普遍地给它增加了广度以及精度。我想他应该在世界大路上开设一个大旅馆，全世界的哲学家都招待，而在招牌上应该写道："招待人，不招待他的兽性。有闲暇与平静心情的人有请，要寻找一条正路的人进来。"他大约是最清醒的人，我所认识的人中间最不会勾心斗角的一个；昨天和今天他是同一个人。
