| 1 | An assessment of global ocean wave energy resources over the last 45 a显示文摘Against the background of the current world facing an energy crisis,and human beings puzzled by the problems of environment and resources,developing clean energy sources becomes the inevitable choice to deal with a climate change and an energy shortage.A global ocean wave energy resource was reanalyzed by using ERA-40 wave reanalysis data 1957–2002 from European Centre for Medium-Range Weather Forecasts(ECMWF).An effective significant wave height is defined in the development of wave energy resources(short as effective SWH),and the total potential of wave energy is exploratively calculated.Synthetically considering a wave energy density,a wave energy level probability,the frequency of the effective SWH,the stability and long-term trend of wave energy density,a swell index and a wave energy storage,global ocean wave energy resources were reanalyzed and regionalized,providing reference to the development of wave energy resources such as wave power plant location,seawater desalination,heating,pumping. | ZHENG Chongwei SHAO Longtan SHI Wenli SU Qin LIN Gang LI Xunqiang CHEN Xiaobin | 2014 | Acta Oceanologica Sinica2014，33，1： | 22 |

| 4 | The Stability of Unsaturated Soil Slope Affected by Rainfall Seeping显示文摘Because rainfall seeping makes losing stability of unsaturated soil slope, and arouses great loss to production and human being safety, the stability of unsaturated soil slope has been researched by many scholars recently. This article mainly uses the model for the prediction of shear strength with respect to soil suction, developed by Vanapalli and Fredlund to formulate rainfall seeping how to affect the stability of unsaturated soil slope. Firstly, volumetric water content of unsaturated soil slope changes with rainfall duration, and effective saturation changes with its volumetric water content. Secondly, soil volume weight changes with its volumetric water content. Thirdly, matric suction also changes with its volumetric water content. According to these causes, this article researches how much they make the contribution to the minimum safety coefficient respectively. At last, these factors roundly considered, this article gets the rule of minimum safety coefficient of unsaturated soil slope with rainfall duration that is minimum safety coefficient gradually increasing firstly, then decreasing that is composed of two sectors, first is slowly decreasing, then is fast decreasing after some value. | Zhang Shilin Wang Guochen Shao Longtan | 2007 | 工程科学(英文版)2007，5，1： | 0 |
