In the opening segments of sean penn ' s version of into the wild , a mother ' s nightmare of her missing son segues to a freight train curving through crisp alaskan scenery , its long , metal body weaving around snow - capped mountainsides 在西恩?潘版的《荒野伴我心》的开头片段，在一位失踪儿子的母亲的梦魇里的、寒冷而干燥的阿拉斯加风景里，有一列蜿蜒的运货火车，它那长长的金属车身绕着积雪盖顶的山脉迂回行进着。
In order to effectively use the vacant space beside the passenger train paths in the train running diagram of mixed passenger and freight lines and draw more freight train paths to improve the carrying capacity , the essay analyzes the reasonable drawing plan for freight train paths beside single passenger train arid two passenger trains respectively on the double tracked section with automatic blocking system according to the principle of minimal additional removal time and on the basis of the calculation method of removal coefficient table 摘要为了在客货共线运行图中有效利用旅客列车运行线两侧的空档，尽可能多地铺画货物列车运行线，以提高区段通过能力，在扣除系数表格计算法的基础上，按照附加扣除时间最少的原则，分析了在双线自动闭塞区段单列旅客列车和2列旅客列车两侧货物列车运行线的合理铺画方案。
We automobile to see highway on the way that take a walk like the world exposition , the automobiles of every country in the world which crosses over half a century gathers here , the freight train has what the soviet union produced bad - tempered then for four fifty times , there were east windmill which china produced in the 1990s too 散步的沿途我们见到公路上的汽车，犹如万国博览会，跨越半个世纪的世界各国汽车都在这里汇集，货车有四五十年代苏联生产的嘎斯，也有90年代中国生产的东风车。

Products include those used in telecommunications , energy resources , transportation , textiles and other light industries , medicine and health , and engineering and building industries , . for example automobiles ( 9 percent ) , motorcycles ( 60 percent ) , freight trains ( 26 percent ) and coal excavation equipment ( 24 percent ) 产品涉及通信、能源、交通、轻纺、医疗卫生和工程建筑等行业领域，其中有的已占全国产品产量的相当比例，如汽车9 % ，摩托车60 % ，铁路货车26 % ，煤炭综合采挖设备24 % 。
The threats of the security of raiiway freight mostly come from cargoes exceeding over the railway gauge which caused by loading , collision , braking and shaking etc . today , the loading situation is most iy checked manua my , wh i ch can on iy check the ioad i ng s i tuat i on of the static freight train with the low efficiency and precision 随着铁路安全技术装备的完善，现在铁路运营安全的主要威胁来自因装载、冲撞、制动、震动等因素引起的货车所载货物超出铁路货运装载限界。目前，我国铁路货运管理部门主要采用人工测量方法来检测货车超限情况。但是人工测量只能实现对静止货车装载情况的检测，并且检测效率低，检测精度也难以保障。
The press - mounting quality of the rolling bearing has big influence to the rolling bearing fatigue life and safe operation of the freight train . because it is impossible to measure the micro interference fitting contact stress after press - mounting , the department of railway system just uses the press - force as the criteria of the press - mounting quality . but the interference fitting contact stress has big influence to the rolling bearing fatigue life 轴承压装质量对轴承疲劳寿命和铁路货车安全运行有重大影响,当前因为压装完毕之后的微观过盈配合接触应力无法测量,铁道部仅以宏观压装力作为轴承压装质量检查的标准,而过盈配合接触应力轴承疲劳寿命有很大影响。
The automat i c mon i tor i ng on the i oad i ng s i tuat i on of mov i ng f re i ght tra i ns should be implemented to ensure the operation security of railway fre i ght . the paper presents a new algorithm for freight train image segmentation with the aim of minimizing missing gauge - exceeding detection rate based on the image segmentation theory . the prof i le of the freight train and cargoes on the image is obtained with the arithmetic and whether cargoes exceeding the gauge or not is concluded by the location of the freight train and cargoes on the image 本文以数字图像处理原理中图像分割理论为基础，结合货车装载状态监测的实际情况和货车装载状态监测系统对图像分割的要求，以保证超限漏检率最小为目标，给出了货车图像自动分割的算法，获得货车及其所装载货物的分布区域，再根据该分布区域，得出货车装载状态是否超限的结论，从而实现对运行中货车的装载情况的自动监测。
