The design of laid-out curve of circular cone and cylinder intersecting curve is often used in practice.

圆锥或圆柱相贯线的展开曲线的设计是生产实际中常遇到的问题。

If a length of string that is wrapped around the periphery of a circular disk is then gradually unwrapped, a point at the end of that string will follow a curved path that is known as an involute of the circle that is represented by the disk.

如果字符串长度是围绕周边的圆盘，然后逐步展开，这一点在年底该字符串将采取曲线路径，被称为渐开线的循环，所代表的磁盘。

Special solutions for the ring circular domain with crack surfaces acted on uniform compressive force, linear compressive force and linear shearing force are deduced in polar coordinate employed the eigenfunction expansion technique in the Hamiltonian system of elastic mechanics. Combined with the general solution for the above problems, the analytical solutions for crack tip fields with surfaces acted on the above three kinds of loads are obtained. These solutions offer theoretical basis to construct analytical elements for plastic analysis of crack.

从弹性力学哈密顿体系理论出发，利用平面弹性力学极坐标系下的本征向量展开求解，推导了环形圆形域裂纹边作用有均布压力、线性压力和均布剪切力情况下的特解，从而得到了裂纹表面作用有以上三种荷载情况下的裂纹尖端场的解析解，为进一步构造进行弹塑性裂纹分析的奇异解析元奠定了理论基础。

The influence of free surface on tunnels is discussed.The influence of blasting vibration on fresh concrete lining is studied. The finite element method is employed to analyze the spatial distribution of temperature and thermal stress of fresh concrete lining, the wave function expansion method is used to study the interaction of blasting seismic wave and the circular tunnel with lining, thenthe safe PPV of fresh concrete lining with different age is decided by taking into account the thermal stress of concrete lining. Using the conformal mapping method, the influence of blasting vibration on the arch tunnel with lining is studied and the safe PPV of concrete lining is deduced under different incident angle.

研究了爆破振动对新浇混凝土衬砌的影响，采用有限元法求出了圆形洞室新浇混凝土衬砌内温度和温度应力在空间上的分布及其随时间的变化，采用波函数展开法求解了爆破地震波与有衬砌圆形洞室的相互作用，获得了考虑新浇混凝土衬砌内温度应力前提下不同龄期的新浇混凝土衬砌的安全振速；利用保角变换研究了爆破振动对直墙拱形有衬砌隧洞的影响，得到了爆破地震波以不同角度入射时混凝土衬砌的安全振速。

After certain this route, we design the business enterprise image system for it successively, body now the profession concept of the life and health;The subsequent product packs the design circumambience market target consumption exhibitions to open, setting up the market from the competition target of the opponent business enterprise investigation beginning, end assurance design way of thinking and direction.

确定此路线后，我们先后为其设计企业形象系统，体现生命与健康的行业概念；随后的产品包装设计围绕市场目标消费群展开，从对手企业的竞争目标的树立到市场调研开始，最终确定设计思路及方向。

On this basis, the view of the legal status quo, circumvention of the legal system in China started envisaged, the real to seek advantages and avoid disadvantages, and constantly improve our countrys legal system, in order to better for the social development and progress of mankind services.

在此基础上，针对我国法律现状，对我国的法律规避制度展开设想，真正的做到趋利避害，不断完善我国的法律制度，以便更好的为社会发展和人类进步服务。

At daytime, I was driven by instinct of seeking for life to flatter, to fawn, to envy, to play all kind of petty tricks…but at night, all kind of humbleness and depravity made me surprised, just like Dolagler saw the figure conjured by the civet cat, I saw the dust covered on my soul; Memory opened its picture scroll slowly before me, I looked at myself of this day, I felt deep sick with myself.

白天，我被求生的本能所驱使，我谄媚，我讨好，我妒忌，我耍各式各样的小聪明……但在黑夜，白天的种种卑贱和邪恶念头却使自己吃惊，就像朵连格莱看到被灵猫施了魔法的画像，看到了我灵魂被蒙上的灰尘；回忆在我的眼前默默地展开它的画卷，我审视这一天的生活，带着对自己深深的厌恶。

The newspaper said a recent sweep of Guangdong eateries by health authorities uncovered one live civet cat, 14 frozen ones and 18 frozen pieces of other exotic wildlife.

中国日报」表示，最近由卫生单位对广东省餐饮店所展开的清查中，查获果子狸活体一只、冷藏果子狸十四只和其他冷冻外来野生动物十八只。

They rushed clamorously into the presence of the Lioness and demanded of her the settlement of the dispute.

田野里的动物们正在展开一项热烈的争论：那一种动物最应该生最多的孩子。

Meanwhile, it could be seen that there does not exist a confidence interval with width less than 0.5 because of the property of Poisson distribution. Based on these conditions, the author mainly carried out research into two aspects of this problem as follows. Firstly, by numerical and theoretical analysis, the author compares some existent confidence intervals, for example,"exact" confidence interval, Wald confidence interval and Bayesian confidence interval, and finds some deficiencies points of the confidence intervals, whose modification version has been proposed .Also, several better confidence intervals such asare also presented .Secondly, for given confidence coefficient and interval width, the author constructs a class of asymptotical two-stage interval estimate procedures. At the same time, under varies restriction of confidence coefflcientent interval width, the optional sample size of the first stage has been computed by numerical computation. The numerical computation shows that the method considered in this dissertation have good properties and applied value.

同时，由于Poisson分布的特性，我们知道不存在其参数区间长度小于0.5的置信区间，基于这些情况，我们主要展开了以下两个方面的研究：一是利用数值计算分析与理论分析的方法对现有的若干置信区间如"精确"置信区间，Wald置信区间，Bayes置信区间等进行分析比较，发现了一些缺陷，针对这些缺陷，我们进行适当的修正，并得到几种性质较好的置信区间如：修正大样本区间Jeffreys原则下置信区间二是针对已给定的置信系数与区间长度，我们提出了一种渐近的两阶段区间估计程序，并利用数值计算的方法，在各种置信系数与区间长度限定下，算出了最优的第一阶段观测次数，大量数据表明，本文考虑的方法性态良好，具有应用价值。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
