For the purpose of constructing mammary gland specific expressional vector, we use the updream regulation sequence of bovine BLG to regulate lacS gene to express in mammary gland. Positive clone cells are selected and purified by the expression Neo gene and report gene EGFP. So the cells can be used as sources to create transgenic animals by nuclear transfer techniques.

本研究以牛β-乳球蛋白基因上游调控成分作为启动子，嗜热菌糖苷酶基因lacS为目的基因，构建了lacS基因乳腺特异表达载体，并通过脂质体介导法转染体外培养的牛胎儿成纤维细胞，借助新霉素抗性基因和增强型绿色荧光蛋白报告基因来筛选、纯化阳性克隆细胞，为利用核移植技术制备转基因动物提供细胞来源。

With degenerate approximations to the oneway LippmannSchwinger integral equation, we study a category of wideangle degenerate migrators that permit the implementation of seismic migration using fast Fourier transforms alone.

通过对LippmannSchwinger单程波动积分方程的退化核逼近，本文研究了一类宽角退化算子的偏移成像。

Finally, in muon-catalyed fusion, the influence of laser fields on μ~3He muonic atom ionization is studied.

最后，我们研究了μ子催化核聚变中强脉冲激光对介原子μ~3He的电离。

This would cause the original and the mutant plasmids to behave as members of different compatibility groups.

一些病毒有特异蛋白来识别末端，真核染色体遇到的问题是末端复制子。

Oncolysis and suppression of tumor growth by a GFPexpressing oncolytic adenovirus controlled by an hTERT and CMV hybrid promoter［J］.

Recent advances have allowed nucleosome dynamics on promoters to be studied in real time, dramatically changing how we think about gene regulation on chromatin templates.

目前的进展已经能够实时地监控启动子上核小体的动力学改变，戏剧性地改变了我们对染色体上基因调控的认识。

For the spherical shape nuclei, we mainly study the phenomenon of halo. Halo is very common. The main characters of halo are that the valence nucleons are weekly bound and there are large matter root-mean-square radii of nuclei.

在对球形核的讨论中，主要研究了晕现象，晕现象是一种普遍现象，它的主要特征是有弱束缚的价重子以及大的物质半径等。
