Bai Luo Shan(白罗衫)is called“Hamlet”in Chinese opera.Bai Luo Shan was originally a legend written by anonymous people in the Ming Dynasty.It is based on the novel Warning the World·Su Zhi Xian Luo Shan Zai He(警世通言·苏知县罗衫再合),Which tells the story of Sun Yun,which occupies a place in the history of opera and performance.Since the Tang Dynasty,the story of Bai Luo Shan has been widely known among the people,and it has been adpated into a script by a variety of operas.Among them,the Kunqu Opera version of Bai Luo Shan dealing with the protagonist’s dilemma in the face of jurispudence and human relationship shows the contradiction of human nature,strengthens the tragic meaning of the theme,and embodies the unique aesthetic value. 展开更多

The 12 animal calendars of the Chinese zodiac are the essence and source of Chinese civilization,and have been deeply rooted in the production,life,and social activities of various ethnic groups in China since ancient times.The ancient Luo Yue stone inscription1 is a popular ancient script from four to six thousand years ago,and 17,496 characters have been found,which is the earliest script found on the Chinese land so far.A comparative study of Chinese zodiac characters2 between the ancient Luo Yue stone inscriptions and the oracle bone through paleographic conformation reveals that the two characters have the same and similar characteristics.Therefore,this paper intends to further investigate the kinship between the two,and to conduct a preliminary exploration of the origin,development,and evolution of the zodiac by combining recent human archaeological data,emerging molecular anthropological data,historical literature,and data from the Chinese Civilization Exploration Project,in an attempt to show the integration and dependence of Chinese civilization,the pluralistic pattern of Chinese culture,and the Chinese nation for thousands of years. 展开更多

In this paper, the design of a proportional integral controller (PIC) plus fuzzy logic controller (FLC) for the negative output elementary super lift Luo converter (NOESLLC) operated in discontinuous conduction mode (DCM) is presented. In spite of the many benefits viz. the high voltage transfer gain, the high efficiency, and the reduced inductor current and the capacitor voltage ripples, it natured with non-minimum phase. This characteristic makes the control of NOESLLC cumbersome. Any attempt of direct controlling the output voltage may erupt to instability. To overcome this problem, indirect regulation of the output voltage based on the two-loop controller is devised. The savvy in the inductor current control improves the dynamic response of the output voltage. The FLC is designed for the outer (voltage) loop while the inner (current) loop is controlled by the PIC. For the developed ?19.6 V NOESLLC, the dynamic performances for different perturbations (line, load and component variations) are obtained for PIC plus FLC and compared with PIC plus PIC. The study of two cases is performed at various operating regions by developing the MATLAB/Simulink model. 展开更多
