In order to further into research the effect of trans-acting factor TGA1a on expression of exogenous gene in the transgenic plant progeny, different transgenic plants were grown and analyzed. The result of experiments revealed that the separation of resistant gene in the transgenic plant progeny was consistent with Mendel's law of segregation.

对子代植株中gusA基因表达水平进行分子检测和GUS活性测定结果显示，反式调控系统控制下的gusA基因的mRNA转录水平和GUS活性均明显高于对照。

Methods: Twenty-four Kkay mice were divided into three groups(n=8):diabetes group,methionine-diet group,folic acid and vitamin B12 treatment group. C57Bl/6 mice were used as controls(C57). Four months later,the mice were sacrificed and their serum levels of Hcy,folic acid and vitamin B12 were measured by fluorescence polarization immunoassay. Pathological changes in kidneys were examined with the periodic acid schiff method with periodic acid-silver methenamine staining under electron microscope. Expression of MMP-9 protein or mRNA was detected by RT-PCR with immunohistochemical staining. Results: Different morphological changes of DN were found in Kkay mice.

Kkay糖尿病鼠随机分3组：糖尿病组、高蛋氨酸组和叶酸、维生素B12组，C57BL/6鼠为对照(C57)，以相应饲料喂养4个月后取材，测定血糖、血同型半胱氨酸、叶酸和维生素B12，以PAS、六氨银染色法光镜下及超微电镜观察各组DN病变，比较各组肾小球硬化指数；以免疫组化和半定量图像分析肾小球MMP-9蛋白表达，并以RT-PCR检测肾脏MMP-9 mRNA水平。

Firstly, the principle of the iteration method is presented, the characteristic of the method is analyzed. The downward continuation computation for model and practical data with noise of different variance is performed by means of iteration method.

首先介绍了迭代法的基本原理，分析迭代法的特点；然后利用迭代法对不同噪声水平的模型数据和实测数据进行向下延拓计算，研究噪声对迭代法的计算误差影响。

The potential energy surfaces of ground state of He—HBr complex have been calculated at several levels of theory, including the single and double excitation coupled-cluster method with noniterative perturbation treatment of triple excitation CCSD.

在用非迭代的三重激发项来校正CCSD的CCSD理论水平下，采用aug-cc- pVQZ基函数对He—HBr的分子间势进行了系统的研究。

In this dissertation, we investigate the theory of fuzzy number space and fuzzy metric space, the main works of this dissertation are as following

引入了模糊数的台点概念，给出了模糊数空间E〓上Kaleva和Seikkla[54]意义下的水平收敛的等价刻画。

But in B and C groups, the TNF-α level increased after transplantation, and the electron micrography showed us that Kupffer became activation.

而B、C两组随着心跳停搏时间的延长，术后TNF-α的水平逐渐增高，电镜下更可见呈激活状态的Kupffer细胞。

Finally, we observed that the serum TNF-α level decreased gradully in A group after transplantation, and meanwhile the electron micrography revealed that Kupffer cells became from inactivation to disruption and apoptosis.

最后，我们发现A组随着心跳停搏时间的延长，术后血清TNF-α水平不断下降，而同期电镜下可观察到Kupffer细胞从不活跃状态逐渐发展到凋亡和变性、坏死。

METHODS: The effects of different factors on mean diameter of microsphere was studied at three levels accoring to uniform design of experiment.
