After a study on Chinese financial practice, we find that though Chinese banking system has high cost and low efficiency, one side, Chinese security market has very low efficiency to overcome asymmetric information and has many unsolved problems in short term that brings very high additional cost, so security market is not a good system to substitute the Chinese banking system and must develop after these problems are solved, on the other hand, the cost of Chinese banking system is mainly exogenously produced, the experiences of western commercial banking practice and the joint-stock reform in some Chinese banks have proved that the efficiency of Chinese banking system can be improved. So one of our conclusions is that China should emphases on the reform and development of the banking system.

一方面，本文通过对中国证券市场的进一步分析，发现中国证券市场制度设计上存在严重不合理，短期内仍然缺乏合适的生存环境，这也导致其过去十多年的超常规发展中不仅具有低的效率，而且形成了许多短期内难以克服的缺陷，这充分表明证券市场不应成为我国金融体系短期内的重点方向，证券市场未来的进一步发展必须以这些问题和缺陷的解决为前提；另一方面，进一步的分析表明，我国银行业目前的巨大成本主要为外生，同时，对西方发达国家银行业发展和我国银行股份制改革的经验总结表明，只要在一定的条件下，银行业的效率完全可以有效提高，因而，中短期内我国应重点对银行业进行改革和发展，尤其是要加快银行业的股份制改革进程。

Ant routing use Swarm-Intelligence for route discovery and also have multi-paths for backup and balance. However, the efficiency of ant routing can more and more go down in large-scale mobile ad hoc networks. For solving such condition, improving the efficiency of ant routing, this research proposes the algorithm that combines both the GRID and ant routing, called grid-based ant routing algorithm. GARA can improve efficiency of ant routing in large-scale mobile ad hoc networks.

对於解决路由上的一些问题，也因此有各种不同类别的路由方法被探讨，蚂蚁路由演算法利用群体智慧(swarm-intelligence)找寻路径，而且同时能够找到多条备援路径，但是，蚂蚁路由演算法会因为行动主机数目愈来愈多情况下，而导致路由演算法效率降低，因此本论文以GRID为概念，融入蚂蚁演算法中，让蚂蚁是采用网格对网格(grid-by-grid)方式传输，改善蚂蚁路由演算法在行动主机数目愈来愈多情况下的效率与效能。

In middle school, classroom teaching is the principle part in chemistry teaching, in which classroom asking is a very important link.
