中文摘要：

科技知识无疑具有普遍性，但掌握知识却是一个“情境中默会磨合”的实践过程。“7．23动车事故”的出现，反映了在引进和集成国外先进技术时，某些科技人员与领导干部暴露出方法论上“照方抓药”的机械式思维方式。这种拿来主义的线性思维，忽视了科技知识中的不确定性问题，出现了研发中急功近利的“大跃进”，再加上某些领导干部好大喜功的政治压力，最终导致了“7．23动车事故”的发生。

英文摘要：

It is undoubted that scientific and technological knowledge is universal, but the mastery of knowledge is a ＂tacit grinding--in process in situation＂ of practice. ＂7.23 bullet train accident＂ reveals that when introducing and integrating advanced technology abroad, some scientific and technical personnel and leaders show mechanistic thought of filling a prescription on methodology. The linear thinking ignores uncertainty problems of scientific and technological knowledge, and results in ＂Great Leap Forward＂ with going for quick gains in R ＆ D stages, along with political pressure impressed by some administrative leaders who crave for greatness and success; and all of these, eventually lead to the 7.23 bullet train accident.
