下面的例子使用了dfn元素来标明术语定义。 - Finally , some simplification methods to the model were studied and a modified block elimination contraposing the features of the model ' s linear system was developed , which can greatly decrease the model ' s requirement to computer resources . in the second part , numerical methodology of hybrid techniques was developed , which uses dfn models developed in the fist part to build continuum approximations of fractured rock
第三，本文将一种用离散的水?气分界面模拟非饱和渗流的数值模型扩展到裂隙网络中，为用本文所构建的离散裂隙网络模型模拟裂隙岩体成富拥要柳厅录非饱和渗流提供了一个初步的框架。 - The results showed that pcr applify a 485 specific molecular band in 672 individuals , the rate of positive reaction is 60 % , southern blot result shows a strong signal in transgenic fish . it is concluded that hu - - ifn gene has been integrated and expression . it is also that foreign gene integrating position and copy number is different individuals , by elis a detecting , 23 . 5 % transgenic fish " were detected hu - - ifn gene expression in all 672 transgenic fish , but expression level of hu - - dfn is significant difference in different individuals and growth period
2000年共显微注射32197粒草鱼受精卵，出苗12945尾草鱼鱼苗，经孵化培育最后获得1120尾五寸左右草鱼，对1120尾草鱼提取血液总dna进行pcr和southern杂交检测， 2000年转导的草鱼的pcr检测结果，有672尾草鱼即600k转化个体的总dna能扩增出一条485kb的特异分子带，说明转化个体整合有huj ifn基因，经southern杂交进一步证实，转入的抗病相关基因己在转基因草鱼体内染色体上得以整合，但整合位点没有固定区域，整合的拷贝数存在较大差异。
