This paper introduced the main Tibetan coding methods at home and abroad, and described mutual conversion from nonstandard to national standard（GB18030）,national standard to international standard according to different cording structure, and then realized it on Vista platform. It provides convenient tool for information exchange and processing in Tibetan and lays a foundation for the further development of Tibetan information.

The identity between pmDmrt2 and the Dmrt2 of Danio rerio, Xenopus Laevis , Gallus gallus , Mus musculu ,Homo sapiens is 95%, between pmDmrt3 and the Dmrt3 of Danio rerio, Oryzias latipes, Gallus gallus, Rattus norvegicus,Homo sapiens is 85%, and 97% between pmDmrt4 and the Dmrt4 of Oryzias latipes and Takifugurubripes. Our results further reveal the evolutionary conservation of the DM domain gene family in both invertebrates and vertebrates.

序列分析表明，pmDmrt2编码的氨基酸序列与斑马鱼、爪蟾、红原鸡、家鼠、人等的Dmrt2的一致性为95 %；pmDmrt3编码的氨基酸序列与斑马鱼、青鳉、红原鸡、家鼠、人的Dmrt3的一致性为85%；pmDmrt4编码的氨基酸序列与青鳉、红鳍多纪鲀的Dmrt4一致性高达97%，进一步证明该基因家族在无脊椎动物和脊椎动物都具有高度的进化保守性。

ABSTRACT Fractal image coding, which is also called attractor image coding, is a emergent method of image compression during the last decad...

分形图像编码方法是近十年来诞生并发展起来的一种新型图像压缩方法，它将图像编码为一组收缩映射，由这组收缩映射的不动点近似待编码对象。

The codingoperator expresses the genes with N-decimal system floating numbers, and then the genes are divided into integer part and decimal part. The two parts are encoded into chromosomes respectively. The corresponding selection, crossover and mutation operators are designed with the theory of symbol encoding and the properties of N-decimal system floating numbers.

该编码算子首先将每个基因值用N进制的浮点数表示，然后将其分为整数部分和小数部分，分别重新编码组成染色体；相应的选择、交叉、变异算子采用符号编码的思想，充分利用N进制浮点数的特点进行设计。
