Chapter five examined the independent usages of the localizers in Shi Shuo Xin Yu, in which the most active one is adjectival usage.

余论中第一次系统讨论了中古时期合成方位词的出现以及汉语史上方位习语的形成问题。

As far as China's agriculture concerned, with global competition at trade of product of agriculture and resource redistribution within world wide, agriculture in China is needed to go out of our national boundary and inosculate with international world, and become the one important part of economic integration, as well as find its stand in international admeasurement.

加入WTO后，中国经济将主方位地与国际接轨。对于农业来说，随着农产品贸易的国际化竞争，资源在世界范围内的流动和配置，要求中国农业走出国界，融入国际，成为全球经济一体化的重要组成部分，并在国际分工中寻找自己的地位。

The conventional aerotriangulation solves only the elements of exterior orientation 〓ω,κ, X〓, Y〓, Z〓 of photo, whereas the elements of interior orientation x〓, y〓, f of aerial camera are often determined in the laboratory. As the laboratory methods can not take into full account the actual conditions in aerophotography, large deviations often occur.
