湘莲的本草考证

通过查阅古今典籍,并结合现代研究对湘莲的源流、名称、品质进行本草考证。经考证,湘莲品种来源清晰,品名历史悠久,品质优良,为发展和利用湘莲提供理论依据。

红芪的本草考证

目的:为红芪的道地性及品质研究提供参考。方法:查阅历代本草著作,从异名、释名、基源、品质及道地沿革5个方面对红芪进行本草考证。结果:历代本草中多将红芪列入黄芪项下,作为黄芪使用;经历史变迁终与黄芪区别运用,现指多序岩黄芪(Hedysarumpolybotrys Hand.-Mazz.)的干燥根。据本草记载,红芪的道地产区多为甘肃、四川、山西、陕西、内蒙古等地。结论:历史上红芪来源复杂,品质参差不齐,原产地变迁较大,现主要分布在甘肃陇南、定西地区,一般被认为是甘肃的道地药材,具有悠久的生产历史。

Examination for Experimental Verification of Improvement of Power Quality in Distribution System by PCS

In the future, the power quality will decrease by the introduction of a lot of renewable energy sources. The topic of this research is a new method of operation of PCS （power conditioning systems） in the future distribution system. The purpose of this research is development of PCS with a function of improvement of the distribution system. Therefore, the authors propose a method of the power quality improvement of the distribution system by PCS. In addition, the authors construct the control logic to use in PCS The control logic suggests adding harmonic restraint function to conventional control. These were verified by simulation and an experiment. As the results, we confirmed that basic operation of PCS being carried out, harmonics were restrained, and power quality had improved.
