By using the empirical formulae of the ship resistance, the sailing resistance computation of the ship team for Three Gorges Project open channel navigation has been conducted.

Starting from the angle of the circulating organization, this paper demonstrates the necessity of establishing the farming circulation channels taking the co-op as the intermediary organization, analyzes on the existing problems in this field, and puts forward some innovative ideas.

This paper analyzes on the difficulties of Chinese small and medium-sized enterprises in the circulation channel,and taking the development history of E-commence Corporation Alibaba as the example,advances some methods for solving the problem of widening the circulation channel of Chinese small and medium-sized enterprises with the manner of developing the public E-commence platform.

Therefore,analyzing the construction of its formation,development and circulation channel of coal distribute system in China is very important for further standardizing the market and improving circulating efficiency.

The author believes that there are different modes of channel for China s Auto industry and there are still some problems with China s auto distribution channel mechanism.

Model ship and real barges-tow tests for TGP s diversion channel navigation;

The similarity principle and test technologies for ship model are described;meanwhile,using the result of the ship model test to research the channel navigation of TGP is explained.

The Three Gorges Project adopts the construction scheme of 3-stage river diversion and channel navigation.
