The World Trade Organization was precisely acknowledged the technical trade barrier reasonable permitted its existence at the same time, simultaneously also saw the technical trade barrier unreasonable has at the same time formulated "Technical Trade Barrier Agreement", came the standard and limits various member nations the technical trade barrier behavior, guarded against stops appears to technical trade barrier abusiveness

世界贸易组织正是承认了技术性贸易壁垒合理的一面而允许其存在，同时也看到了技术性贸易壁垒不合理的一面而制定了《技术性贸易壁垒协议》，来规范和限制各成员国的技术性贸易壁垒行为，防止出现对技术性贸易壁垒的滥用

The first one is capital barrier, which means a large amount of initial capital for the perfect monopolizer. This prevents the common enterprise from entrance. The second is the technical barrier, i.e. the monopolizer is in control of certain technology and knack while other enterprises not, and then the market naturally become a monopoly market. Scale economy is the most studied technical barrier. The third one is law barrier, i.e. some exclusive patent rights are protected by the law. For example, patent and copyright are the monopolizations protected by the law. The fourth one is tactic barrier, even without any of the above mentioned barriers; it can also set up barriers through other ways, such as huge amount of advertisement investment.

首先是资本壁垒，即完全垄断企业的起始资本量很大，因此一般的企业难以进入；其次是技术性壁垒，即垄断者掌握了某种生产技术和诀窍，其他企业则没有，这个市场也就自然成了垄断市场，规模经济是一种被研究得最多的技术性壁垒；第三是法律壁垒，有些独家经营的特权是由法律所规定并受到法律保护的，专利和版权就是法律特许的垄断；第四是策略性壁垒，企业即使没有上述三种壁垒，也可以通过其他方式高筑壁垒，例如巨额广告投入。

The new non-tariff barrier system consists of technical barrier, environmental barrier, social barrier and moral barrier.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
