H9N2 virus has been widely distributed in wild birds and poultry around the world since its first emergence in the United States of America in 1966(Gu et al.2017;Carnaccini and Perez 2020).The virus appeared in chickens in China in the early 1990s,and over the last two decades has gradually become the dominant epidemic subtype(Sun and Liu 2015;Bi et al.2020).Although H9N2 virus infection alone cannot cause severe disease or death in poultry,H9N2 virus-infected birds experience a degree of egg production drop and can be easily infected by other pathogens,thus causing economic losses for poultry industry.

Forestry industry is an important commonweal and fundamental industry. Forestry enterprises take the burden of ecological construction and supply of forest products, and economical benefits, ecological benefits, and social benefits as well. However, electronic-business (e-business), as a completely new business operation model, will bring great opportunities and challenges to forestry enterprises. On the basis of simple analysis of e-business conception model, the internal and external environment for forestry enterprises to develop e-business was thoroughly analysed and researched , and finally effective strategic options were proposed.

作者： Wang xinwen Zhang Xianda he Zhengya(Southeast University, Nanjing 210096)

This paper addresses the problem of adaptive,consistent parameter estimation for a MA model from the 3rd order cumulant of the system output. The proposed adaptive algorithm is derived by using the new linear equation system (J. K. Tugnait, 1990), which is proved to have unique solution,and hence guarantees the consistence of the MA parameters. Simulation results are provided to show the performance of the new algorithm.

对于《离骚》篇题之义的解释,自汉以来歧见迭出,并且由此影响到对诗旨的正确理解。本文从《离骚》文本的内容主旨出发,详考“离”及“离骚”一词在《楚辞》与《史记》等楚汉文献中的实际运用,联系屈原“抒忧娱哀”和司马迁“抒愤懑”的文学美学思想,得出不同以往的结论,认为:以“离骚”为“遭忧、别愁”诸说,与《离骚》诗旨不合;“离”即离开,“离骚”即“离忧”、“离去忧患、解脱痛苦”之谓;屈原、司马迁均有“离开忧患”、“解脱痛苦”的文学观念;诗题即主题,《离骚》前半写“骚”、后半写“离”、《乱》词总结全诗而写“离骚”,即“从彭咸之所居”自沉而死,则是终极意义上的“离骚”,是屈原全部现实忧患、生命痛苦的最高形式的解脱。
