K, the parent element of 40Arr, has different abundance in coal and argillite, which can be used in analyzing the difference between 40Ar/36Ar values of natural gases produced from coal and argillite, and identifying the main gas source in coal source rocks. In this paper, the forming mechanism of 40Arr and its process of entering into gas pool are discussed, on the basis of which a method for identification of main gas source is developed.

本文系统地讨论了 40Ar的形成机理及其运移进入气藏的过程，利用 40Ar的母体元素 K在煤和煤系泥岩中的丰度差异，分析了以煤和煤系泥岩为母源的天然气 40Ar/36Ar同位素组成上的不同，并利用这种差异对煤系中煤岩或煤系泥岩为源岩的天然气藏的主力源岩进行了判识，继而建立了利用氩同位素组成判识煤系烃源岩主力源岩的方法。

This process is makes the improvement in the original two person two-sided synchronized GTAW process which one time welding two-sides formings, we have carried on a series of welding testing on 8mm SUS304, this new process has be able to decrease weld defects on the tradition two person on both sides synchronized GTAW process, shortenned construction work period, increase welding quality, as well as eliminate tradition two person on both sides synchronized GTAW for SUS304 austenite stainless steel in easy emergence of incomplete joint penetration and porosity.

此工艺是在原有的双人双面同步钨极氩弧焊工艺基础上进行的，即将原有的一次焊双面成形改为两次焊成形，经过在厚度为8 mm的SUS304上进行的一系列焊接工艺试验，验证了这项新工艺既减少了传统工艺中繁琐的工艺过程和焊接工艺缺陷，缩短了施工工期，提高了焊接质量，又消除了传统8 mm SUS304不锈钢双人双面同步钨极氩弧焊过程中易出现的未焊透和咬边现象。

This article has mainly studied one kind improved two person two-sided synchronized GTAW craft for the austenite stainless steel. This craft makes the improvement in the original two person two-sided synchronized GTAW craft foundation which one time welding two-sides formings. A series of welding engineer testing on 8 mm SUS304 were carried on. The new craft could guarantee the welding quality in contrast with the original two person two-sided synchronized GTAW.
