1989年是美国国家工程科学院建立25周年。作为庆祝活动的一部分,他们举办了25年来杰出工程成就的评选活动。在各专业工程学会审查推选的340多个项目中,最后评选出10项最杰出的工程成就。按年代顺序依次为:登月、应用卫星、微处理机、计算机辅助设计和辅助制造、CT扫描、高级复合材料、大型喷气客机、激光、光纤通讯、遗传工程产品。很明显,这10项成就间有着密切的联系,并都对人们日常生活产生重要的影响。一、登月 1969年7月20日,人类首次踏上月球,随后又安全返回地面。这是人类历史的一个伟大壮举。阿波罗登月计划是一项巨大的系统工程,其规模和技术复杂性远超过以往任何一项工程。所用土星V三级运载火箭,第一级包括五台推力各为约6700千牛顿的火箭发动机。在阿波罗计划过程中,共成功地发射了12枚。阿波罗 1989 is the 25th anniversary of the founding of the National Academy of Engineering. As part of the celebration, they held a selection of outstanding engineering achievements in 25 years. Of the more than 340 projects reviewed and selected by various professional engineering societies, 10 of the most outstanding engineering achievements were finally selected. According to chronological order: the moon, the application of satellites, microprocessors, computer-aided design and manufacturing, CT scan, advanced composite materials, large jet aircraft, laser, optical fiber communication, genetic engineering products. Obviously, these 10 achievements are closely linked, and all have an important impact on people's daily lives. First, the moon On July 20, 1969, humans set foot on the moon for the first time and then returned safely to the ground. This is a great feat of human history. The Apollo mission to the moon is a tremendous system project that has far more scale and technical complexity than any previous project. The Saturn V-Class carrier rocket used in the first stage consisted of five rocket motors each of about 6700 kilonewtons thrust. During the Apollo project, a total of 12 successful launches were made. Apollo
