Abstract : the paper gives the relevant calculating results of pressure pulse on high - speed trains passing each other , and on the basis of it analyses relation between pressure pulses on high - speed trains passing each other and the main influence factors , such as speed , nose - slenderness ratio , side - wall distance , lengh on high - speed trains passing each other , side - wall height , etc 文摘:给出高速列车会车压力波的有关计算结果，并据此分析会车压力波与速度、头部长细比、侧墙间距、会车长度、侧墙高度和高中速会车等主要影响因素的关系。
Nothing in the provisions of this act relating to the measure of indemnity shall affect the rules relating to double insurance , or prohibit the insurer from disproving interest wholly or in part , or from showing that at the time of the loss the whole or any part of the subject - matter insured was not at risk under the policy 本法有关计算方法的规定，对有关重复保险的规则没有任何影响，并且不阻止保险人全部或部分否定利益的存在，不阻止保险人表明在发生损失时，保险标的的全部或一部分并不处于保险单项下所列的危险之中。
To revise provisions relating to the depreciation of industrial and commercial buildings to cater for changes in market practice to take into account any prior usage of a building or structure in calculating balancing allowances and charges for commercial and industrial buildings and structures ; to deal with the method of computation of annual allowances to be applied to a subsequent user of a building or structure ; and to consolidate and amend the provisions on balancing allowances and charges for both commercial and industrial buildings and structures 3 .鉴于市场上经营手法的改变，修订有关工业和商业建筑物折旧的条文。在计算商业及工业建筑物及构筑物的结馀免税额和结馀课税时，会考虑建筑物或构筑物的任何先有用途处理适用于其后使用建筑物或构筑物的人士的每年免税额计算方法以及合并和修订有关计算商业和工业建筑物及构筑物结馀免税额及结馀课税的条文。
The retaining wall reclining on the slight slope built on soft foundation is usually used in protecting the shore of river , the contradiction between the lack of impartiality in stress of the base and the small stress allowed by the foundation as well as the lack of stabilization of the breast wall is a hard nut to crack in the engineering . in the paper , a tenon - base is added under the base of the retaining wall , on the study of the choice of the parameters and formulas used in calculation and the research of theory used in calculation , method used to deal with the load , etc , the writer gives a way to crack the nut mentioned above paragraphs and presents a qualitative and quantitative analysis about them , such as the equivalent inner friction - angle ( d ) and the passive press of the clay ( ep ) , etc . in the end of the paper , using modern optimization method , a design of the retaining wall reclining on the slight slope built on soft foundation is done , the result is economical , and accords with the fact 软基上的仰斜式挡土墙在水利工程河道护岸中经常遇到，仰斜式挡土墙基底偏心应力较大和软基土地基容许承载力偏小的矛盾以及挡土墙抗滑稳定不足是工程中难以解决的难题。本文在对仰斜式挡土墙设计中有关计算参数的选择、公式的选用应该注意的问题进行了研究，对河道护岸软基础上的仰斜式挡土墙采用凸榫基础处理的方法，就其计算理论、设计验算中各荷载的具体处理方法进行了较为细致的研究，提出了解决软基础上的水工仰斜式挡土墙难以解决的难题的方法，并对有水情况下粘土等效内摩擦角_ d 、凸榫被动土压力e _ p等在计算中的取值提出了定性和定量的分析。最后利用现代优化方法对软基础上的水工仰斜式挡土墙进行了结构优化设计，得出了符合实际的结果，与其它重力式挡土墙形式进行比较，取得了明显的经济效益。
And here we can see that for many problems the man hours involved in terms of changing the data formats and bringing up the different software tools and trying to see what the data is saying , that ' s the overwhelming percentage , and breakthroughs there would have incredible leverage , even beyond just the part about the computational modeling 而且在这里我们能看见有数许多问题男人小时之久积极叁与的在变更数据格式而且提出不同的软件工具而且尝试看见什么数据正在说的术语，那是压倒性的百分比，而且突破性的发展在那里会有难以置信的杠杆作用,甚至超过有关计算的靠模切的只是部份。
