苏、美所用<展开修正值数据表>包含m_1和m_2两个数据表,每次需经两次查表计算才可获得m值数据。我国航空、航天工业中沿用的是五十年代的苏联资料,其适用范围已不敷现代技术发展的需要。经研究推导出m值计算公式,利用计算机计算、分类、编排、打印、现已印制成具有12万个数据的m值数据表,从而使工艺技术人员既可利用计算机,也可利用新数据表快速检索,准确可靠。
Su, the United States used to expand the correction data table contains m_1 and m_2 two data tables, each required twice to look up the table to obtain m-value data. The data of the Soviet Union in the 1950s are used in China’s aviation and aerospace industries. Their scope of application is no longer sufficient for the development of modern technology. The m value calculation formula is deduced from the research, and the m value data table with 120,000 data has been printed out by computer calculation, classification, arrangement and printing, thus enabling the technician to use both the computer and the new data Fast retrieval table, accurate and reliable.
