It is found that the distributed microscopic traffic network simulation methods based on distributed systems require not only the careful discussions on traditional traffic flow theory, such as the driver's uncertain behaviors in selecting the route and changing lane, but also some deep researches on parallel techniques. These key techniques about how to realize parallel and distributed simulations include how to partition the large-scale road network into sub-areas, how to divide the multi-course in dynamic traffic flow operation, how to finish the informational transmission among processors, and how to realize the clock-synchronization among processors etc..

In exceptional circumstances, a dream to the delicious food, will stimulate saliva secretion, saliva secretion increased, it will lead to drooling; improper sleeping positions sometimes lead to the phenomenon of flow of saliva; Some people sleep regularly teeth and stimulate the brain nerve center, to promote saliva secretion, so that flow of saliva; some people love spicy food thing, or, tobacco, liquor, so that night, dry mouth, increased saliva secretion; sleep, mouth breathing tends to dry mouth, thus contributing to an increase in saliva secretion ; In addition, some diseases, such as infectious stomatitis, toothache, mercury, potassium iodide poisoning, but also can stimulate an increase in saliva secretion, causing sleep drool.

是对美食的梦想，会刺激唾液分泌，唾液分泌增加，会导致流口水，有时睡觉姿势不当导致的唾液流现象，有些人睡眠定期牙齿和刺激大脑神经中枢，促进唾液分泌，使唾液流动，有些人喜欢吃辣的东西，或者，烟，酒，所以这天晚上，口干，唾液分泌增加，睡眠，口呼吸往往口干，从而促进在唾液分泌增加，此外，如传染性口腔炎，牙痛，汞，碘化钾中毒的一些疾病，而且还可以刺激唾液分泌增加，造成睡眠流口水。

Weigh's addition minishes the loss of net's volume in pure current, but makes no differnce in the pure wave condition. After installed of sinking ring or lower ring, the loss of net's volume is decreased. The loss of net volume is more in the current combined with wave condition than in the pure current condition.

在纯流条件下，增大配重均有利于减小网箱的体积损失；而在纯波条件下，配重的增加对于改善网衣的变形没有实质性的意义；设置了底圈或沉降圈后，均能在一定程度上减小网衣的体积损失；波流组合条件下网衣的体积损失要明显大于纯流条件下的体积损失。

The above problems are studied in this thesis. First, the implicit NND scheme with mix flux splitting method proposed by Zhang Hanxin that is first order accurate in time and second order in space is modified. The modified scheme keeps the characteristics of fast convergence and is second order accurate both in time and space. It can be capable of simulating the unsteacly flow. Second, the topological method founded by Zhang Hanxin is improved to study the characteristics of vortex near the singular point on its axis and the cross streamlines on the longitudinal section passing the vortex axis. On the basis of topological results, a program which visualises numerical results is made out. It can help us analyse the characteristics of vortex motion.
