As to the editing style, there mainly were editing by style, by year and by place, and we can understand the writing style and literature opinion of that time through dividing of writing style. It was very broad to select for woks then, poetry could not be put into works in North-Song Dynasty, but could be in South-Song Dynasty. We can inspect the change of literature idea of study of poetry in Song Dynasty. It is free to publish the works then. There is no limitation for publishing and selling works in Song Dynasty, this means the literature then was becoming Commercialization, and this commercialization had deep influence for the development of Chinese literature.展开更多

Nevertheless, until 1997 the scientific literature reported little information about the process of crystallization by cooling through which the commercial product is obtained. In particular, the available studies were aimed to investigate only the kinetics of nucleation and crystal growth neglecting some effective aspects of the industrial crystallization in mechanically stirred apparatus. In order to fill that sci-tech gap, the Department of Chemical Engineering at the University ＂La Sapienza＂ of Rome decided to lead a long and meticulous experimental research on the crystallization in discontinuous （batch） of CAM （citric acid monohydrate） in the allotropic form that is stable at room temperature. Due to the number of people involved in that pioneering work, carried out in the historic laboratories of＂La Sapienza＂ （Faculty of Engineering）, and motivated by the publication of related M.Sc. dissertations and research papers, such collective effort was called ＂School of Industrial Crystallization＂. Among the graduate students in Chemical Engineering that 17 years ago participated in that fruitful experience there was also the author who, under the supervision of Prof. Barbara Mazzarotta, had the specific task of assessing the effects on CAM of changing the crystallization operating conditions until their optimization; the achievements are briefly illustrated in this paper.展开更多
