一、前言为了解隔板的全位场的位移和应力,测定残余变形,估价隔板的可靠性和研究破坏机理,并且充分暴露隔板潜在疵病,我们选定闵行电厂九号机第十六级焊接隔板为对象,进行试验。这是我厂产品中汽叶最长的焊接隔板,该级隔板于1973年8月12日投运以来, I. INTRODUCTION To understand the displacement and stress of all the baffles, to determine the residual deformation, to evaluate the reliability of the baffles and to study the failure mechanism, and to fully expose the potential flaws of the baffles, we selected the tenth Six welding partitions for the object, the test. This is my factory products, the longest blade welded diaphragm, the level of the diaphragm on August 12, 1973 put into operation,
