摘　　要：介绍了国内直埋热力管道型式试验规范标准发展情况,结合工作实践,通过对TSGD7002—2006《压力管道元件型式试验规则》和CJ/T 200—2004《城镇供热预制直埋蒸汽保温管技术条件》等标准规范进行讨论,对沙箱试验、保温性能试验、产品覆盖范围等方面存在的问题提出了改进建议。With the increasing of bilateral trade agreements in East Asia,integration is the ultimate demand,however,trade negotiations concerned agriculture has always been one of the major resistance.Through divided phases constant market share（CMS） comparative analysis of the labor-intensive and capital-intensive agricultural products based on the ASEAN ten countries and China,Japan and South Korea three countries,the author obtained： the overall market demand potential for agricultural products in East Asia area is great;it can improve the competitiveness of agricultural products to some extent with reasonable and proper industry and the structure;the share of China＇s agricultural products exports is relatively large,but mainly rely on low prices and competitiveness is weaker and weaker;the trade policy made by government and external opportunity will play increasingly important roles in agricultural products trade in future and the regional economic cooperation is a kind of choice.
