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。

But, on controlling of the cost, there is a great limitation in traditional product-centered cost calculation system.

从激烈的市场和煤炭企业自身的情况看，煤炭企业提高价格和提高产量的方法是行不通的，只有通过内部自身进行有效的控制成本才是提高煤炭企业经济利益的根本途径，而在控制成本方面，传统的以"产品"为中心的成本核算体系存在很大的局限性。
