而船舶优先权是船舶物权中争议最多的领域，故笔者采用比较的方法分析研究，以船舶优先权为主线，从船舶优先权与船舶抵押权和船舶留置权的对比中更深入地对船舶优先权从多角度浅作探讨，并提出自己的若干观点或建议，同时希望能起到抛砖引玉的效果。

In this thesis, firstly, some main models have been checked on their accuracy, and the reliability of MACORS code has been verified by the RELAP5/MOD2 code on five transient conditions for QSNP: loss of flow; loss of offsite power; incontrollable control rod withdrawal; the feed-water temperature increasing and the feed-water lost. The results obtained are very satisfactory. Secondly, MACORS is used to calculate the operating and accident transients for QSNP, and the analysis results are significant to real engineering. And finally for MNRS, MACORS is used to simulate the steady-state natural circulation heat-removed capacity and the transient behaviors from forced circulation to natural circulation. Some important conclusions are obtained by the analysis results.

The research of this paper includes three parts: the first, according to the statistical figures about the cargo transport in recent years, it analyzes cargo transport structure and the changing law and the internal reason of cargo transport. At the same time it analyzes and calculates the change of the arriving ships" structure for a systematic and full understand of the transport demands. The second, it make a scientific forecast of the port"s future cargo capacity making use of the grey forecast system, which provides scientific basis for medium-long term development plan of the ports cargo handling capacity. It also makes some analysis and research for medium-long term development future of Zhangjiagang port in use of physical unit analising technique, looks for the scattered no-order and no-system reason of medium-long term development. On the basis of summarizing their experience, the article adopts physical unit model to make a comprehensive judgement.
