The Response of Debris-Flow Events to Solar Proton Flares （Ⅰ）

By analyzing the observation data from Dongchuan Debris Flow Observation and Research Station and historical data from year 1965 to 1990 gotten from National Astronomical Ob-servatories/Yunnan Observatory,the responding of debris flow in Jiangjia Ravine to Solar Proton Flare is studied. The following conclusion can be drawn. Solar Proton Flare,as one of most im-portant astronomical factors,affects the activity of debris flow in Yunnan. Generally,from 1965 to1990,the more active Solar Pro-ton Flare is,the greater the probability of high frequency and large runoff of debris flow is. On the contrary,the less active Solar Pro-ton Flare is,the greater the probability of low frequency,small runoff,and low sediment transport of debris flow is.     

当前高校心理健康教育的现状及对策探讨

当前,高校的心理健康教育中仍然存在着许多问题,主要表现在:对心理健康教育的本质认识不清,将心理健康教育混同于德育,重诊疗、轻预防发展,从业人员的专业化水平低等.针对这些情况,高校应正确认识心理健康教育,将心理健康教育与德育有机结合起来,加强队伍及体制建设,构建科学的心理健康教育体系,切实将心理健康教育落到实处.

APPLICATION OF BORON MODIFIED SILICA SOL ON RETENTION AND DRAINAGE

INTRODUCTIONRecently with the high speed, large-scale develop-ment of papermaking, in the manufacture of paper and paperboard conventional single and dual reten-tion and drainage systems cannot obtain satisfying re-tention and drainage. So in 1980 microparticulate systems appeared. Because of its superiority such as good retention effectiveness on fine and chemicals, improving drainage and paper formation, reducing waste water and enhancing the concentration of white water for good recover…     

Bang bang control of unified chaotic system

The unified chaotic system contains the Lorenz system and the Chen system as two dual systems at the two extremes of its parameter spectrum. This paper presents the design of bang bang controller for unified system and multitude of numerical experiments under various control parameters. Numerical experiments meet the theoretic proof perfectly and convincingly demonstrated the controller can be effectively used for unified systems with uncertainty of the equilibrium points. The method enriches the applications of chaotic control.
