As an classical book which disputes endlessly on the completed time but systematic and detailed record on official function, rituals and sacrificial vessels, Zhouli (Rites of Zhou) has become a paradoxical existence: on the one hand, it’s a crucial reference document frequently quoted for reconstructing the propriety in the past dynasties and explaining the ritual remains in modern archeology;on the other hand, its authenticity and edition age are always questioned. So the completed time of Zhouli is still a bottleneck problem and cannot be ignored. This article focuses on the tradition of sacrificial jade Bi and Gui based on the written documents and archeological findings, demonstrate once again that Zhouli was completed in early Han dynasty. 展开更多

Interest in the ore\|forming histories of basins has grown rapid since 1960 and is now intensive. The main reason behind the acceleration is the increasing awareness that the natural processes responsible for generating metal deposits in the sedimentary basin from the source rocks of the beneath the basin and intensively hydrothermal activity in the basin. Observations made in different continental margin basin systems and superlarge deposits in Chinese Yunnan\|Guizhou\|Guangxi Province on the eastern margin of the Qingzang (Himalaya—Karakoram—Tibet) were investigated in terms of geodynamics of basin formation. Geotectonically, the area is situated in the conjoint between the Tethys—Himalaya and the Marginal\|Pacific tectonic domain, characterized by very complex geological structure, typical basin\|mountain tectonics, abundant Superlarge deposits. 展开更多

In this work, we apply the Zhou’s method [1] or differential transformation method (DTM) for solving the Euler equidimensional equation. The Zhou’s method may be considered as alternative and efficient for finding the approximate solutions of initial values problems. We prove superiority of this method by applying them on the some Euler type equation, in this case of order 2 and 3 [2]. The power series solution of the reduced equation transforms into an approximate implicit solution of the original equations. The results agreed with the exact solution obtained via transformation to a constant coefficient equation. 展开更多

In traditional folk music research, when many questions can not be answered from the literature.Please go to the fields and go to the places where these folk music used to be or is being spread. In the fields, we can objectively record the traces of the artists 'activities with words, images, or videos. After careful analysis and consideration of the folk tunes while they performed in musician's mouth and hands, we will get unexpected results."Hai Zhou Five Main Tunes (HZFMT)"is a typical case. If you only look at the literature, it is only a local folk narrative tunes. It is not uncommon throughout the country. However, if we go deep into the field investigation, after comparison and analysis, we can see that some of the singles music is the art of Sanqu singing that did not disappear from the Ming and Qing dynasties. These tunes are not lost, but they are handed down from generation to generation in the art population. It is also an art treasure created by the salt merchant culture 展开更多
