It"s considered that the algae blooms control function in the algae"s growth dynamics model is influenced mostly by the water temperature, sun illumination, water flow speed and the concentration of the nutriment in water. A function including the four elements was built. By using cell mapping algorithm and contacting with the practical water condition of the Wujiang river and the Hanjiang river we analyzed and computed the algae blooms in the two areas and found the result was very near to the practical result. And we found that the ascend of water temperature and the descend of the water flow speed will contribute to the growth of algae and the nutriment is the substance basis of the algae blooms but not the only element. It must be under the condition of condign water temperature, enough sun illumination, slow water flow and abundant nutriment that algae blooms may break out unexpectedly.

本文认为藻类生长营养动力学模型中的水华爆发控制函数主要受水温、光照强度、水流速和营养盐浓度的影响，构建了包含水温、光照强度、水流速和营养盐浓度的水华爆发控制函数，通过对乌江、汉江的水华爆发进行胞映射分析，得到的计算结果与实际监测非常吻合，并认为水温升高和水流速下降将有利于藻类生长，营养盐是水华爆发的物质基础，但不是唯一因素，必须在适宜的水温、光照、缓慢的水流和充足的营养盐条件下，藻类才可能出现突发式的"疯长"，即水华爆发。

Second, we rewrite the simple path expression into SQL statements. We research the different rewriting techniques for the different mapping nodes and different condition in where clause. For the query optimizing, we propose the path index based on the notion of node equivalence which is computed by bi-simulation algorithm.

Experimental results show the recognition rate of the method is 95%for a known expresser and 72% for a novel expresser. Aiming at the shortcomings of optical flow technique,two improved optical flow algorithms are presented.One way is to introduce forward and backword constraint eqution and Hessian matrix of optical flow equation is computed.The well- posedness of each point of local neighbourhood is examined and the weight of Lucas-Kanade's method is defined as the reciprocal of the conditioning number of its Hessian Matrix.

3针对传统光流法的缺点，分别提出了两种不同的改进方法：其一为引入前向-后向光流方程，计算其Hessian矩阵，把Hessian矩阵条件数的倒数作为Lucas-Kanade光流法的加权阵，可有效消除局部邻域中不可靠约束点，同时提高基本约束方程解的稳定性；其二为针对传统光流法只适用于刚体运动的特点，在扩展约束光流方程的基础上引入了div-curl样条函数作为扩展光流约束方程的附加约束条件，给出了一阶和二阶div-curl样条约束下光流的数值解。

In this paper, fuzzy theory, Markov chain and RFM model are integrated to evaluate customer lifetime values. This approach calculates the profit contribution of customers in every purchasing situation. Firstly, customer purchasing state is updated contiguously by fuzzy theory and RFM model with transition matrix which represents the probabilities among purchasing states. Then the profit contribution of each period is computed by using revenue and cost data. Finally, the profit contribution of each customer is accumulated through some discounting consideration. This will construct the final customer lifetime values.

本研究结合模糊理论、马可夫链、和RFM(recency， frequency， monetary； RFM)模式，配合折现模式来计算顾客终身价值，其中模糊理论及RFM模型定义顾客之购买状态，马可夫链则推算顾客在每期购买状态改变的机率，然后推估出顾客在每期交易的转换机率，再结合产品的收益与成本资料，算出顾客在各期对公司的利润贡献，最后将各期的利润贡献折现加总，计算出各种购买状况下的顾客价值，利用此顾客价值就可指出哪些是对企业有利的顾客。
