我们的声发射技术是适应无损检验的需要,遵照毛主席关于“独立自主、自力更生”的方针,从无到有,逐步建立并发展起来的。声发射自六十年代开始发展以来,多用于无损检验方面,既能作为一种对材料进行评价的手段,又可用作构件的安全监控工具,已在许多工业部门应用。几年来,我们建立起自己的声发射技术的过程,也是不断批判刘少奇、林彪崇洋迷外的修正主义路线,打破帝国主义和社会帝国主义的封锁和技术垄断的过程。在决定建
Our acoustic emission technology is to meet the needs of non-destructive testing. In accordance with Chairman Mao’s guideline of “independence and self-reliance”, it has been gradually established and developed from scratch. Acoustic emission has been used in many non-destructive testing since it began to develop in the 1960s. It can be used as a means of evaluating materials and as a safety monitoring tool of components. It has been applied in many industrial sectors. In the past few years, we have established our own technology of acoustic emission. They have also constantly criticized the revisionist line that has left Losangeles and Lin Biao in the midst of the temptation to break the imperialist blockade and technology monopoly of imperialism and socialism.
