去年我們編写了一本水庫大型閘門的加工技术条件,当时是坐在設計大楼內查資料、照着“框框”編出来的,結果規定了不少脫离实际的要求。譬如焊縫,大部分要求用γ射綫透視百分之二十五到五十,到底必要性如何?按这个要求去作需要多少人力?多少时間?多少胶片?也没有調查研究。 Last year, we prepared a processing technology condition for a large reservoir gate. At that time, we sat in the design building to search for information and compiled it in accordance with the “framework”. The result stipulated a number of requirements that were not practical. For example, weld seams, most of which require γ-rays to see through 25 to 50 percent, are necessary. According to this requirement, how much manpower is required to make? How much time? How much film? No investigation.
