This chapter emphasizes on the five issues. Firstly, the relation between the transformation from savings to investment and the fund's formation. Its purpose is to reveal the formation way of the funds and how to improve its efficiency of utilization. Secondly, the analysis of the supply behavior of the transformation from savings to investment. It mostly analyzes the savings' behaviors of the government, enterprises and residents and their economic effects. Thirdly, the analysis of the demand behavior of the transformation from savings to investment. It stresses on discussing the enterprise's choices of the financing structures and forms on the premise of pursuing the maximum profit, through analyzing the basic features of each social financial entity. Fourthly, it clearly points out the kinds of transformative mechanism from savings to investment and its impactive factors. Finally, it emphases the importance and realizing path of the transformative mechanism in our country that is changed from combining bank with capital market to the market leading, through analyzing the mechanism and its practice in China.

In order to overcome the technological difficulties encountered in the course of insulation fault diagnosis on the base of dissolved gases analysis, several kinds of mathematic models and actualized methods are brought forward to improve the reliability and veracity of fault diagnosis of transformers. The research works are shown mainly as followings:1 A modified fuzzy multi-criteria method is brought forward for insulation fault diagnosis of transformer. Furthermore, a new method for insulation fault diagnosis is proposed on the base of fuzzy multi-criteria together with rule reasoning. With fuzzy diagnosis in the method, fault reasons are filtrated and then the reasons in low probability are prohibited, Moreover, the left reasons are testified by using rule reasoning and then final concludes are drawn in much less misjudge probability and better results.2 On the base of geometry characteristics of C- partition to sample set of DGA data of transformer, a method is put forward to compute effective radius of neighbor field of a sample, number of clusters and values of initial centers. Moreover, the fuzzy C- means cluster model with adaptive weight is brought forward in the first time and then the fault classifier is designed for insulation fault diagnosis of transformer.3 According to the weakness of the degree of gray of gray incidence, a new formula to compute DGI is put forward and then incidence order criterion is ascertained. Moreover, a new DGI model for fault diagnosis is proposed according to the further analysis to relationship between fault reason and content of oil dissolved gases of transformer.
