Because of the deeply national crisis in 20 century ,and the western s second expansion constrained traditional Chinese ideology to reform itself to modernization ,while the traditional art losed its bloom and livingness , it had been taken to a unreasonable reform ,which was in the huge reform storm , and the inside theory was evolution .

20世纪初中国由于国家危机深重，西方的第二次扩张迫使传统儒家意识形态下的中国进行现代化转形，处在边缘状态的传统绘画艺术早已失去了往日的光华和应有的活力，在以进化论为思想核心的变革大潮中绘画被推向了错误的改良风尖。

The culture medium is composed of human keratinocyte serum free culture medium +2.5 mg/L bovine pituitary lixivium +5 μg/L epidermal growth factor+438 mg/L glutamine, glutamine can promote the growth of the keratinocyte.

采用改良的无血清培养技术进行人体角质形成细胞的培养，培养基为人角质形成细胞无血清培养基+2.5 mg/L牛垂体浸出液+5 μg/L表皮生长因子+438 mg/L谷氨酰胺，其中谷氨酰胺能促进角质形成细胞的生长。

A modified algorithm for high-speed lossless data compression is presented in this paper.

本论文提出了一套改良式高速无失真资料压缩演算法，有效地改善了文献上所提的方法在压缩效率方面不佳的缺点。
