Then based on this theory and the concept of local controllability, a series of existence conditions for the asymptotic state observers of 2DGM are proposed. These conditions are analogous to the corresponding well-known results in 1-D case. Finally the related design methods and the 2-D separation property theorem are also presented.

Fisher(1930)shows how capital markets increase the utility both of economic agents with surplus wealth and of agents with investment opportunities that exceed their own wealth by providing each party with a low-cost means of achieving their goals The Fisher Separation Theorem demonstrates that capital markers yield a single interest rate both borrowers and lenders can use in making consumption and investment decisions, and this in turn allows a separation between investment and financing decisions.

费希尔（ 1930年），可见资本市场，提高公用事业双方的经济代理人与剩余财富，以及代理商与投资机会超过他们自己的财富，提供每一个党同一种低成本的方式实现自己的目标费雪的分离定理证明资本标记产量单一利率均借方和贷方可以使用，使消费和投资决定，而这反过来又使分离之间，投资与融资的决策。

The public hospital groups feasibility analysis and the group government structure analysis introduced the basic content of modem company government theory, and thought the hospital group exterior government was most basic, and at the same time the most important constituent of the group management. By the means of Fisher separation theorem under complete capital market, it proved the importance of the organization existence and strict implementation, on which we proposed the best government structure of public hospital groups. And through the hospital group prestige model, it further explained the public hospital execution group management is the effective method to remold the public hospital property right, and to solute property right problem.

公立医院集团化的可行性分析及集团治理架构介绍了现代公司治理理论的基本内容，认为医院集团的外部治理是集团治理中最基本的同时也是最重要的组成部分，通过完备资本市场下的Fisher分离定理论证了，在公立医院的国有资产管理中代理机构存在和实施严格管理的重要性，提出了笔者设想中的公立医院集团的治理架构，并通过医院集团声誉模型进一步说明公立医院施行集团化经营是重新塑造公立医院产权主体、解决产权虚置问题的一种可供选择的有效手段。

Firstly properties of the HJ SDF are revealed, and some useful conclusions are obtained. Then by the HJ SDF's properties and the two fund separation theorem, the mean-variance spanning is investigated and the spanning condition is gotten. It is proved by the mathematical method that the spanning condition gotten from HJ SDF is equivalent to the spanning condition gotten from the other methods.
