Firstly, the natural frequencies and normal mode shapes of the fluid-conveying pipe with zero fluid velocity (i.e. U=0) were determined with the transfer matrix method. Next, these natural frequencies and normal mode shapes were used to derive the equation of motion for the fluid-conveying pipe with fluid velocity U.neq.0 by using the expansion theorem. Finally, the free and forced vibration responses of the pipe with flowing fluid were obtained by means of the Jacobi method and the Newmark direct integration method.

Result The inhibitory effect on pulmonary metastasis of transplanted tumor were 46.36%, 32.73%, 18.2% in the Runing granule preparation group, warming kidney group, dispersing liver and promoting blood circulation group respectively. There wasn't significant difference between Runing granule preparation group and CTX group (50.91%). The expression of VEGF was dropped in Runing grannie preparation group and dispersing liver and promoting blood circulation group. The expression of TIMP-1mRNA was up-regulated in Runing Granule group and warming kidney group. The expression of MMP-9 was dropped in Runing granule preparation group and warming kidney group.

This thesis consists of five chapters. At first, We introduce the study history as well as present situation on KKM theory. Secondly, We discuss the invariability of transfer open valued multimap under the restriction of upper and lower semicontinuity on generalized convex spaces. Then, We obtain new KKM type theorems from the classical KKM theorem by applying upper and lower semicontinuity. We also obtain intersection theorems by applying the KKM type theorems for a multimap from a topological space to another topological space. Further, We obtain Ky-Fan type coincidence theorem by applying known variational results on the KKM type theorems. Finally, We give an application to new theorems.
