In this paper, it is studicd the characteristics of flow-induced oscillation and sound radiation of streamlined protuberant special cavities. From which three important conclusions are drawn. The first, in water and in casc of low Mach number, there exist two oscillating modes in the cavity: natural oscillation and hydrodynamic oscillation of the cavity. The second, the cquation between Strouhal number and Mach number of hydrodynamic oscillation is put *** third, in water and in case of low Mach number, the equation of the incre ment of general sound level of flow-induced oscillation in direct proportion to square of flow rate is given.

在公共政策执行中,横向政府间由于微观自利性与集体宏观理性矛盾,容易导致"集体行动困境"。"经济人"和"资源稀缺"假设成为博弈起点,通过集体行动逻辑视角对横向政府间政策执行的博弈分析,发现在博弈实证方面,政治上"试点权"谋夺和政绩考核竞赛、市场上"市场壁垒"和"道德风险"、制度上"税费让利"和保护性法规政策是其博弈场域。因此,推动横向政府间进行执行合作,走向正向博弈,需要在政治层面上进行选择性激励,在市场层面上进行权属界定,在制度层面上进行外部强制,使其走出集体行动困境。

Chinese Journal of Acoustics 1990年第3期9卷 231-240页

Ultrasonic velocities have been measured in single phase Bi_1.7 Pb_0.3Sr2CaCu2O8+x and Bi1.7Pb0.3Sr2Ca2O10+x polycrystalline samples. Anomalous changes of both longitudinal and transverse velocities were observed near 200K, which indicates that some structural phase transitio might occur. The elastic constants of these samples have been determined from the measured ultrasonic velocity data, which are much smaller than those of YBa2 Cu3 O7-y and BaTiO3, manifesting that the interlayer coupling will dramatically decrease when the c - axes of the unit cells of these perovstite-like multilayer ceramics increase. The values of Poisson ratio, however, of those ceramics are very close, implying similar interatomic bonding forces. Corrected to void-free state, the Debye temperature of these materials is estirnated as 270 ±20k. The temperature dependence of Debye temperatures for these materials is also calculated by using the same method and reported for the first time.

Purpose: Choroidal neovascularization (CNV) plays an important role in pathogenesis of age-related macular degeneration (AMD), ocular histoplasmosis syndrome (OHS) and so on. However, mechanisms of CNV formation are not fully understood. The aim of this study is to investigate the correlation between expressions of CD105 and vascular endothelial growth factor (VEGF) in experimental laser-induced CNV in rats. Methods: CNV model was established by 532 nm laser photocoagulation in Brown-Norway rats. The expression of CD105 and VEGF in CNV was observed by immunohistochemistry at 3, 7, 14, 21, 28 and 56 days after laser photocoagulation. The image analysis was performed with the professional software of Image-Pro Plus. Results: Fluorescein angiography showed fluorescein leakage in CNV from days 7 to 56 after photocoagulation. VEGF expression was mainly observed in vascular endothelial cells, ganglion cells, inner nuclear layers and retinal pigment epithelial cells in normal retina and vascular endothelial cells in normal choroid of the rats. On day 3 after photocoagulation, VEGF began to express in laser-induced lesions. VEGF was strongly expressed in CNV after 7 days (P0.05). CD105 was initially presented in CNV at 7 days and obviously expressed at 14 days after photocoagulation (P0.05). There was notablely direct correlation between CD105-positive-microvessel density and positively semiquantitative scoring of VEGF in the CNV(r=0.989, P<0.01). Conclusions: There is direct correlation between the expression of CD105 and VEGF in the laser-induced CNV in rat. It suggests that CD105 and VEGF might participate in the new blood vessel formation and promote the growth of CNV.
