In this dissertation, two derivatives of aniline containing polyoxyethylene substituent m-phenylene diamino formyl alkylenediamine poly acetate and poly-3-aminobenzoate were designed and synthesized. And then, comb-shaped polyaniline grafted by PEO were prepared by chemical oxidation copolymerization. The structure of copolymers were characterized by FTIR, ultraviolet-visible spectrum, elemental analysis and TEM etc..

本文在设计并合成两种含聚氧乙烯取代基的苯胺衍生物——间苯二氨基甲酰己二氨基甲酸聚氧乙烯乙酸酯和3-聚氧化乙烯单甲醚基苯胺的基础上，采用化学氧化法将它们与苯胺进行共聚，制备出了聚氧乙烯接枝聚苯胺的梳型共聚物。

Mutation rate at exon of GH in five bovine species was very low with the percentage of 3.48%. The majority of nucleotide substitution was nonsense mutation and only one missense mutation was observed. Molecule tree based on haplotypes of bGH at exon 5 showed that differentiation was apparent relatively between Bubalus bubalis and Bos taurus, Bos indicus, Bos grunniens, Bos frontalis. There was no apparent differentiation among other four bovine species and they shared mutual ancestral sequence.

序列分析表明，5个牛种GH基因外显子5的遗传变异水平较低，平均核苷酸变异率约为3.48%，而且绝大多数位点的核苷酸替换是同义突变，仅发现1个错义突变位点；从GH基因外显子5序列单倍型构建的分子进化树来看，水牛与普通牛、瘤牛、牦牛及大额牛的分化相对比较明显，其他4个牛种之间并无明显分化，还享有共同的祖先序列。

Based on the I-V characteristics of single-electron transistor and the concepts of CMOS digital integrated circuit design, a full adder which consists of 28 complementary SETs is proposed.

基于单电子晶体管的IV特性和CMOS数字电路的设计思想，提出了一种由28个互补型SET构成的全加器电路结构。

Methods Select316cases out of pregnant women who are free from synˉdrome in the pregnant period of weeks from36 +1 -41 +6 in the position of head down,Check the delivery with the deˉterctor of fetus funiculus blood SRF608and analyze the result of test,and evaluate the fetus-neck-winding and preˉdiction of funiculus blood.

对我院2002年1月～2002年12月的住院孕妇中，随机选择孕周36 +1 ～41 +6 周头位、单胎，无妊娠并发症的孕妇316例，临产后采用SRF608型胎儿脐血流检测仪检测，并对其检测结果进行分析，对脐带血流预测脐带绕颈及胎儿预后予以评价。

Treating cubic and five—order Hermitian interpolations as the trial functions of generalized coordinates in time domain, both single— and two—step algorithms for dynamic analysis are formulated respectively.

采用三次和五次Hermite插值多项式在时间域上作为广义坐标的试函数，分别建立了位移型单步及两步时间元模型。

Furthermore, older haplotypes were detected in the two groups, respectively. Possible refugia are inferred in western Hubei Province and SW China during the glacial period.

我们在最小生成树的两个组中推断出一些古老单倍型，并推测在冰期时湖北和我国的西南地区可能是该物种的避难所。

Results Eleven cases of TBMN in children were showed as isolated hematuria, glomerule with normal appearance or slight change and characterized by diffuse thin basement membrane in ultrastructural observation( the thickness of GBM＜ 200 nm, and dense-layer＜ 100 nm).

结果：11例小儿TBMN临床主要表现为单纯血尿，无其它明显的阳性体征，光镜下肾小球无明显改变或轻微异常，未见蛋白管型，包曼囊内及肾小管腔内可见渗出的红细胞，电镜下GBM广泛变薄，平均厚度＜200 nm，致密层厚度＜100 nm。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
