With economic development, the rock material is widely applied in the water conservation、 resources mining、 the civil construction 、 the railway and so on, a lot of problem about rocks urgently is demanded to solve, so there are very important theory and realistic meanings to thoroughly research its nature、 concerning and destroying mechanism,Due to natural function, massive joint and crack with rock, though the scale of these is small, it changes mechanics nature of rock greatly and reduces deforms mould and intensity parameter, and makes it presenting aeolotropy .

随着我国经济建设的发展，岩石材料被广泛应用于水利、资源开采、土木建筑、铁路等领域，与此同时出现许多岩石方面迫切需要解决的问题，所以对其性质、本构关系、破坏机理的深入研究有重要的理论意义和现实意义。由于天然作用，岩石内部存在大量的节理和裂隙，虽然这些裂隙的规模不大，但裂隙的存在大大地改变了岩体的力学性质，使其变形模量及强度参数降低，且使岩体的力学性质呈各向异性。

The paper draws linear unusual differential equation a_0y~(n+a_1y~(n-1+…+a_(n-1)y′+α_ny=∑mi=0k_iδ~(i from the practical problems in the engineering field of electronic technology,circuit analysis,mechanics of materials,mechanical design and civil architecture,discusses the dependence of the solution of the equation on that of homogeneous,gives the algorithm of the equation,and draws the general algorithm of semi-odd number rank unusual Bessel differential equation.

在电子技术、电路分析、材料力学、机械设计和土木建筑等工程技术领域中，常会遇到一类非齐次项为奇异函数的广义线性微分方程，本文给出这类奇异微分方程的解对齐次解的依赖性，从而得出这类奇异微分方程的解法，求出了半奇数阶奇异Bessel微分方程的通解。如下列应用问题中的微分方

The principal stress traces of an object are often drawn by hand, or at most drawn with a French curve, which induces the results very inaccurate.

在土木建筑工程中主应力迹线是布筋方向的依据，但是在工程中通常都是徒手或用曲线板近似绘制主应力迹线。

空气化工产品有限公司提供一整套高性能的环氧树脂固化剂、聚酰胺和改性胺固化剂，可应用在涂料、土木建筑工程、胶粘剂和复合材料等多个领域。

The guyed mast structure is made of soft cables and slender mast shaft, which dynamic characteristics are very complicated due to its large displacement and nonlinearity. Because its complicated theory is not fully understood yet, the damage probability is relatively high under normal design, construction and material.

桅杆结构是由纤绳和杆身所组成，其大变形及几何非线性使得其动力特性十分复杂，在正常设计、建造及材料情况下，桅杆破坏发生的比例之高在土木建筑中是罕见的，这主要是因为桅杆结构复杂的工作机理尚未完全被揭示。

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.
