Properties of efficient portfolios and the efficient frontier to the model are systematically analyzed. Our main results concerning the properties are: every efficient portfolio can be solved by minimizing portfolio risk under a given level of portfolio return or by maximizing portfolio return under a given level of portfolio risk; on the efficient frontier, the risk is a convex and strictly increasing function of the return and the return is a concave and strictly increasing function of the risk; the utility function on the efficient frontier can be expressed as a quasi-concave function of the risk or the return if the investor's utility function is quasi-concave.

从理论上系统地对该模型下的有效投资组合和有效前沿的性质进行了分析，结果表明：每一个有效投资组合可通过在给定期望收益水平的条件下最小化投资组合风险来获得，或者在给定风险水平的条件下最大化期望投资组合收益来获得；在有效前沿上，风险是收益的严格单调递增凸函数，收益是风险的严格单调递增凹函数；当投资者的效用函数是拟凹函数时，则有效前沿上的效用可表达成风险或收益的拟凹函数。

The value of mineral resources consists of absolute mineral rent and the first differential mineral rent on the basis of effect value theory, default value theory and Marx s ground rent theory.

矿产资源的价值理论以效用价值理论和稀缺价值理论为基础，加上马克思的地租理论，从而可以得出矿产资源的价值由绝对矿租和第一级差矿租两部分组成。

In chapter two, under non-Lipschitz condition, the existence and uniqueness of the solution of the second kind of BSDE is researched, based on it, the stability of the solution is proved; In chapter three, under non-Lipschitz condition, the comparison theorem of the solution of the second kind of BSDE is proved and using the monotone iterative technique , the existence of minimal and maximal solution is constructively proved; in chapter four, on the base of above results, we get some results of the second kind of BSDE which partly decouple with SDE, which include that the solution of the BSDE is continuous in the initial value of SDE and the application to optimal control and dynamic programming. At the end of this section, the character of the corresponding utility function has been discussed, e.g monotonicity, concavity and risk aversion; in chapter 5, for the first land of BSDE ,using the monotone iterative technique , the existence of minimal and maximal solution is proved and other characters and applications to utility function are studied.

In this paper, we made a specification on the random variables of utility function with Odd I Larsen's research results, also chose a logit discrete choice model for estimation of Norwegian data, and got the relationship between private car use and costs.

本文采用了基本的微观经济学的消费者效用最大化理论作为模型的基础，在效用函数的随机变量部分采用了挪威莫尔德大学的Odd I Larsen 教授等的计算方法，并采取了logit 离散选择假设，对挪威的汽车消费数据进行了估算，得出了关于挪威汽车消费与汽车费用关系的一些有价值的结论，并推出了相关的政策建议。

In the financial theory, BSDE is usually used in the study of economic theory such as recursion utility, differential utility and the pricing of contingent claim.

在金融理论中，递归效用、微分效用、未定权益定价等经济理论的研究都能用到BSDE理论。

In order to solve dynamic, complicated and uncertain problems, multi-agents based distributed intelligence decision support systems, description and decomposition of complicated decision tasks, and cooperation and reasoning among multi-agents are elaborated in this paper. The details are given as follows. 1. Agent and ABDIDSS modelsIn allusion to the current problems of research on agents theory models, payoff and probability factors are introduced on the basis of mental state models of classical BDI of agent and joint BDI of multi-agents in this paper, mental state models of individual agents and joint metal state models of group agents based on payoff and probability factors are built up. Introducing payoff and probability factors satisfies requirements of uncertainty and self-benefit of agents to the environments.

Different point basically is reflected in:(1) is on philosophical foundation, former it is guidance with Marxism philosophy, latter is directive;(2) to be on the purpose of research and jumping-off place with subjective idealism and metaphysics, former it is to be surplus value theory to lay a foundation, supply thought weapon for proletarian revolution, latter is to be bourgeois to serve;(3) to be on value source, former position works alive is the only fountainhead of value, latter thinks effectiveness or the fountainhead;(4) that effectiveness rate is value finally are on value Standard Dimension however, former consider as socially necessary labor time, latter considers as limit effectiveness to wait a moment.

不同之处主要体现在：(1)在哲学基础上，前者以马克思主义哲学为指导，后者以主观唯心主义和形而上学为指导；(2)在研究的目的和出发点上，前者是为剩余价值理论奠定基础，为无产阶级革命提供思想武器，后者则是为资产阶级服务；(3)在价值源泉上，前者主张活劳动是价值的惟一源泉，后者却认为效用或最后效用程度是价值的源泉；(4)在价值度量标准上，前者认为是社会必要劳动时间，后者认为是边际效用等等。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
