一、引言 我国社会主义建设高速度的发展,对于合金钢的要求愈来愈迫切,合金钢对于重工业、轻工业和国防工业,都是一种不可缺少的材料。高钒低铬合金钢是我国最近新试制的一种特殊合金钢,它具有钢紧密,硬而坚韧,和弹性良好等特性。(1)因此随着我国科学技术的发展,它的应用将会愈加广泛,生产出这种特殊的钢材也就愈来愈多,对于钢中高钒低铬含量的快速测定,生产上非常迫切要求解决。目前钒铬的测定方法很多,但它们测定钒铬含
I. INTRODUCTION The rapid development of China’s socialist construction has made the demand for alloy steel more and more urgent. Alloy steel is an indispensable material for heavy industry, light industry and national defense industry. High-vanadium low-chromium alloy steel is a new trial recently in our country a special alloy steel, it has a steel tight, hard and tough, and good elasticity and other characteristics. (1) Therefore, with the development of science and technology in our country, its application will be more extensive and more and more will be produced for this special steel. For the rapid determination of high vanadium and low chromium in steel, it is very urgent to produce solve. The current determination of vanadium chromium many ways, but they determine the vanadium chromium
