新农村视角下农民参与式小型水利

用水户参与式灌溉管理是我国近年来在总结本国管理体制基础上结合国际管理经验提出的一项重大改革。新时期倡导“坚持以人为本，构建和谐社会”的社会主义“新农村”建设与发展过程中，国家高度重视农村基础设施的建设发展特别是农村水利设施，那么农村小型水利工程参与式管理体制目前状况如何、今后如何围绕“新农村”发展将是新时期农村水利管理体制发展所面临和需要解决的。     

尿素配施氯化铵对菜心产量及其品质的影响

利用盆栽试验，研究尿素配施不同比例的氯化铵对菜心硝酸盐积累的影响，结果表明：随着尿素配施氯化铵比例的增加，菜心氯含量增加，硝酸盐含量下降，而全N含量、叶绿素含量和收获前的产量变化不大。

Research on the Realization of Remote Controlling for Multi-output Power Supply of Communication Equipment Based on Ethernet

According to the requirements of communication power supply, such as high reliability, wide application and high availability, the authors raise a new remote control design for a multi-output power supply for communication equipment based on TCPIP protocol and embedded technology. Then the hardware design is given for the system is discussed based on Ethernet professional chip PRTL8019AS and related circuits. The firmware software design for the salve-computer based TCPIP technology, and the soft design of communieation and control for the master-computer are proposed based on Winsoek and MFC technology in detail A test machine is built to do the testing, the test results prove that the test machine works stably and well, satisfies the design rules and also provides a feasible method for the remote supervise in communication power supplier whose requirement includes remote supervise, no-people on duty and so on.     

An Analysis of Principal-Agent of Game under the Asymmetric Information in Venture Capital

The relationship of investors and venture capitalists is an important part in venture capital. Based on asymmetric information, this paper analyzes the principal agent relationship between investors and venture capitalists with game theory. And this paper mainly discusses the choosing, controlling and incentive problem. It suggests that only the capable and self confident venture capitalists could accept the terms of the limited partnership. It also indicates that recompense mechanism which holds the interest of investors and that of venture capitalists tightly is the center of the limited partnership. Rate of yield is the key of recompense mechanism, it not only reflects the incentive on venture capitalists, also reflects the share of risk between investors and venture capitalists. At last, the market credit play an important role in venture capital.
