救赎：寻求民族文化的出路——解读莫里森的《柏油孩子》

高速铁路具有高度集成、高精度的技术特点，运营过程中经受列车质量、速度、密度等多种因素影响，地理位置因素往往是影响铁路设备状态演变的决定性因素。采用网格化管理技术可将空间上连续分布的管理对象划分成较小的单元网格，有利于从空间位置角度研究管理对象状态的变化规律。随着信息系统技术、大数据技术的迅猛发展，基于位置而不是基于专业更符合高速铁路的管理需求，网格化管理技术给高速铁路管理带来了新的视角。

Management Theory and Key Technology of Grid in High speed Railway

High speed railway, which has the technical characteristics of high integration and high precision, subjects to various influence factors of train weight, speed, density and so on in the operation process. However, the geographical position is often the decisive factor which affects the state evolution of railway equipments. Using the grid management technology can spatially divide continuously distributed management objects into smaller unit grids, which is conducive to studying the change regulations of the management objects state from the spatial perspective. With the rapid development of information system technology and large data technology, grid management, based on location rather than profession, is more in line with the administration demand of high speed railway. Grid management technology has brought new perspective for high speed railway management.
