利用比较原理，算子谱理论及Turing理论，得到了正解的一些先验估计，正常数平衡态解的Turing不稳定性及正常数平衡态解的一致渐近稳定性。

When the production function was general, using theory of control and theory of stability, this paper discussed the production effect of government expenditure and fiscal policy, and got the expression of economic growth rate and structure stability of the economic variables when the production function was constant return to scale or increasing return to scale or decreasing return to scale, and pointed out how the interrelated parameters affected economic growth rate.

摘 要：在生产函数为一般形式时，利用控制论及定性理论的基本方法，讨论政府支出的生产效应和此时的财政政策。得出了当生产函数为规模收益不变、递增和递减时，经济增长率的大小及此时相关经济变量的定性结构，并指出了各种情况下相关参数如何对经济增长率产生影响。

The development of its theory has gone through two stages, at the first stage, its theory and practice is concentrated on the interactions of family members, and is relationship oriented; at the second stage, its theory and practice are influenced by feminism, multi-culturalism, constructivism, social constructionism and ecological systems theory, and takes on a multi-integrative characteristic.

家庭系统理论的发展经历了两个历史阶段，第一个阶段的理论和实践非常重视家庭成员之间相互作用的过程，具有关系取向的特点；第二个阶段的理论和实践因受到女权主义、多元文化主义、建构主义、社会建构论及生态系统理论的影响，呈现多元综合的特点。

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。
