为加速我国科学技术的发展,早日实现四个现代化,第三机械工业部于一九七七年十一月下旬召开了“激光全息摄影在叶片测振及三维位移定量分析中应用技术交流会.”这次会议重点交流、讨论了激光全息技术在航空发动机零部件振动应力形变分析中的应用,特别是发动机叶片振动和三维位移场的定量分析.会议共有31篇有关资料,大会上报告了20篇,如606所、608所和同济大学的“用单张激光全息图对三维形变的定量分析报告”受到代表们的好评.他们不仅做了大量工作,取得了一定的成绩,而且试验
In order to speed up the development of science and technology in our country, four modernizations were realized at an early date. The 3rd Machinery Industry Department held the “Symposium on Application of Laser Holography in Quantitative Analysis of Vibration and Three-Dimensional Displacement of Blades by late November 1977. ”The meeting focused on the exchange of laser holographic technology to discuss the vibration of the components of aero-engine parts of the deformation analysis, in particular, the blade vibration and three-dimensional displacement field of quantitative analysis of the meeting a total of 31 relevant information, the meeting reported 20 The articles 606, 608 and Tongji University, “Quantitative Analysis of Three-Dimensional Deformations with a Single Laser Hologram,” were well received by delegates who not only did a great deal of work and achieved some success but also experimented
