6月19日，国新办举行"新征程上的奋斗者"中外记者见面会，围绕"新征程上的高铁先锋力量"与中外记 者见面交流。 冯江华认为，关于中国高铁的变化，从技术的角度可以用四个"更"来描述。一是更高速。从最早的时速 200公里跃升到350公里，再到前不久下线时速400公里的CR450AF动车组，中国高铁速度越来越快。二 是更高效。CR450AF采用了新一代高效永磁牵引系统，节能效果显著，与"复兴号"现有的异步牵引技术 相比，效率提升了4%。三是更智能。"复兴号"高铁融合运用了北斗导航、5G通信、智能驾驶等技术， 高铁变得更加"聪明"了。四是更安全。以CR450AF动车组为例，整列车装配了4000多个监测点，实时监 测列车的运行状态，还采用了超视距系统，让高铁具备了提前感知前方线路突发状况的能力，为旅客出 行提供了坚实的安全保障。 在高铁出行更加方便背后，是中国技术创新的不断突破。中国中车（601766）株洲电力机车研究所有限 公司总工程师冯江华介绍，在长达30多年的技术攻关过程中，自己和团队潜心钻研，开展了上万次的试 验研究，攻克了许多"卡脖子"技术，解决了许多技术难题，推动轨道交通关键技术迭代升级。 "记得在全球领先 ...
