Under the test conditions of ud = 2800v and 350hz switching frequency , the current in three phase inverting test reached to loooar . m . s , which can fully meet the requirements of 350km / h emu with 2600v link voltage and 950ar 在中间直流环节电压u _ d = 2800v ，开关频率为350hz的条件下，逆变的试验电流达到了1000ar . m . s ，完全能够满足350km h高速动车组对变流器中间电压2600v 、输出电流为950ar . m . s的要求，表明了地面试验机组的研究获得了成功。
“ therelatively higher price of the newly running high speed bullet train is due to a series of factors ， such as the state ofthe art technology ， enormous cost on research and development ， fastspeedandsuperior service experience . however ， the railway department will consider about the reduction of the fare according to market demand fluctuation . ” re - marked wang yongping ， the spokesman from the railwaydepartment 铁道部新闻发言人王勇平昨日表示，刚刚开行的时速为200公里及以上动车组的票价比其他列车要贵一些，与动车组本身的技术含量高、投入成本大、时速快、服务优质等因素有关，铁道部将根据市场规律，考虑今后票价的下浮问题。
While speaking highly of railway ' s achievement since the 16th cpc national congress , chairman jia noted that the chinese people have built the world ' s top - notch qtr line while relying on our own strength , and chinese railway people have developed and manufactured 200km / h and 300km / h emu trains and high horse - power locomotives through introduction , digestion , absorption and re - innovation , thus making a major contribution to the building of an innovation - oriented country 他对党的十六大以来铁路工作取得的成绩给予充分肯定，指出，中国人依靠自己的力量，建设了具有世界一流水平的青藏铁路；通过引进消化吸收再创新，设计制造了达到世界先进水平的时速200公里、 300公里动车组和大功率机车，中国铁路为建设创新型国家作出了巨大贡献。
Introduction of the features , present operation and development of tilting trains . in " londyan - zhanping - xiamen railway line , passenger train speed must be increased and trip time shortened in order that railway transportation may compete with high - speed highway transportation . while operating tilting emus is a feasible approach 介绍摆式列车的特点、运用和发展状况；在“龙岩-漳平-厦门”线上，要与高速公路运输竞争，必须提高旅客列车运行速度、缩短旅行时间，开行摆式列车动车组是较为可行的途径。
The paper discusses the present situation of cleaning equipment hr high - speed trains in both china and reign countries , introduces the research results of the automatic cleaning equipment for the high - fast - speed motor train unit , and analyzes the flowchart , brush sets , automatic control system and their successful utilization in the engineering practice 论述国内外高速列车清洗设备的现状，介绍高速（快速）动车组自动清洗设备的研究成果，分析工艺流程、刷组设备、自动控制方案及在工程实际中的成功运用。
