At present , in existing railway line ' s design criterion in china , the stipulate for plane and vertical section ' s design parameters is on the premise of design speed at 140km . p . h , however nowadays high - speed railway is on the premise of design speed at over 200km . p . h 目前，我国现行铁路线路设计规范中对平、纵断面设计参数的规定是以设计速度为140km h为前提，而现今的高速铁路都以设计速度为200km h以上为前提。
By improving the method of sampling of taking the sample cubes in the vertical section instead of from both end and middle of the alloy ingot , the analytical results obtained were in consistency , and the deviations found were quite small values and reasonable 通过改进取样方法，即将原来从铝合金锭的中间及两端截取块样，改为在铝锭的任意位置纵断面切块取样，有效地克服了不同激发点所得结果存在明显偏差的问题，使所得分析结果相互之间的偏差值很小而合理。

Through using for reference main research methods of high - speed wheel - rail railway line ' s main technique criteria , this paper studies main technique criteria of maglev railway line , brings forward some advised datum of magelv railway line , and puts up dynamical analysis with computer 本文主要是通过借鉴高速轮轨铁路线路平纵断面设计标准的主要研究方法，对高速磁浮铁路线路平纵断面线形和设计参数值进行研究，提出了一系列设计参数建议值，并在计算机上进行了动力学检算。
Designers can use it to finish vertical alignments designs on computer " s screen by using mouse or keyborads freely and conveninently . thus , it can not only improve the level of softwares " practical application but also raise the efficiency and quality of design through cutting down designers " tedious formaltities works greatly 通过鼠标拖动或键盘参数输入，设计人员可以在计算机屏幕上方便灵活地进行路线纵断面设计，不仅增强了软件的实用性，而且大大减轻了设计人员的烦琐的工作量，提高了设计的效率和质量。
In the fourth chapter , based on the analysis and design of some modules closely relating to interactive design , the thesis completes the development of the railway location interactive design subsystem , and these modules are : railway horizontal line interactive design , comparison of plane , profile and across section , automatic and interactive design of profile , designing railway location by across section and setting location of the bridge and the tunnel 第三章分析了线路方案比选工作过程中所涉及的数据情况以及数据管理方法，完成了方案比选综合数据管理子系统的开发工作，第四章通过对线路平面交互设计、内插纵横断面地面高程、纵断面自动与交互设计、横断面定线、桥隧工程设置等与交互设计密切相关的重点模块的分析与设计，完成了交互式线路设计子系统的开发。
Operating speed is carried on to evaluate highway alignment consistency in this paper . calculating formula of operating speed on the horizontal and vertical section is brought out through kinetics of the kinetics of truck . predicting model of operating speed is brought out , with considering about the factor influencing operating speed , which provides important foundation for designing and redesigning highway and have important reference value 本论文提出了用运行速度来评价公路线形的连续性，从汽车动力性能出发，推导出汽车在平面、横断面和纵断面上的运行速度计算公式，综合考虑影响运行速度的各方面因素，采用叠加法建立了运行速度预测模型，为设计和改建公路提供了重要依据，具有重要的应用参考价值。
For the reasons of accumulated soils and sands and the amount of precipitation , the volume in the reservoir is dynamic . if the volume in the reservoir is not dispatched correctly , it will result in the overflowing of the dam bank of the reservoir , even in the collapsing of the darn 库容又是水库调度不可忽视的问题，而库容又与水库的横、纵断面、水位、水深有关，由于泥沙淤积、降水量多少等原因，水库水量是动态的，不对水库水量正确调度，会在大洪水时，造成水库堤坝漫溢甚至垮坝。
