The composite powders consisted of Si, Ni, Ag and a series of Si-Ni alloys. The SEM and TEM results showed that the composite powder consisted of clusters with space and network structures. The composite electrode exhibited higher reversible capacity and the initial columbic efficiency was up to 87 %, which was much higher than that of the pure Si electrode.

The results showed that the temporal-spatial distribution pattern did not alter basically from May 2002 to May 2006, and the topsoil congregative type of soil salinity profiles was the majority in the Yellow River Delta, which indicated that the risk of soil salinization was great, and the level of amelioration and rational utilization for saline soils needed to be improved further in the Yellow River Delta.

结果表明：从2002年到2006年，该地区土壤盐分剖面类型的空间分布格局基本没有改变，黄河三角洲土壤盐分剖面类型总体以表聚型为主，这表明黄河三角洲土壤盐渍化风险大，必须进一步提高盐渍土的治理和合理利用水平。

Parameters based on chemical shift indicate that methyl is a substituent with electron-withdrawing inductive effect and poor electron-donating conjugative effect. Perhaps its conjugative effect is on critical point. Methyl is electron-withdrawing for benzene relative to H. Otherwise, methyl has strong p-position and weak o-position orientation effect.

化学位移值表示的诱导效应参数表明甲基具有吸电子诱导效应，经校正后的化学位移值表示的共轭效应参数表明甲基具有微弱的给电子共轭效应，甚至其共轭效应有可能正处于给电子和吸电子的临界状态，总之相对于氢原子，甲基具有吸电子效应。

The results are consistent with the interpretation that positive intangible information tends to trigger institutional herding on the buy side.3. The securities Investment Funds act as momentum traders in bear market while as contrariant traders in bull market. Further analysis reveals that momentum trading by investment funds intensifies stock return momentum but stock price experiences a long-term reversal. It indicates return momentum results from mispricing instead of risk. The securities Investment Funds hamper market efficiency when they act as momentum traders.4 Both momentum trading and herding behavior intensify market anomalies and hamper market efficiency. However, momentum trading or herding behavior is the only one of the many aspects of the institutional investor.

第三，机构投资者的动量交易行为会加重了股票收益惯性，这一结论在分别控制股票规模、账面市值比因素后仍成立，并且机构投资者对股票的动量交易行为越强烈，股票收益的惯性也越明显，说明机构投资者具有影响股票价格的能力；进一步的分析表明，惯性利润在长期均实现反转，但反转的周期和程度受动量交易指标值的影响，股票动量交易程度越高，动量收益反转越强烈，反转周期越短，这表明机构投资者的动量交易行为使股价严重偏离其基础价值，在长期，股票价格不断调整逐渐靠近其基础价值，因此可以说，机构投资者对股票的动量交易行为会加重股票收益惯性和阻碍市场效率。

Nei'genetic distance showed Schima superba and Cryptocarya chinensis hadsmall genetic distance between every two subpopulations of each own,but Castanopsischinensis had high genetic distance between every two subpopulations of own.

Nei遗传距离结果表明，荷木和厚壳桂两两亚种群间都有非常小的遗传距离，而锥栗却有大的两两亚种群间遗传距离，表明荷木和厚壳桂亚种群间个体的差异小，有较少的位点频率发生变化；而锥栗亚种群间个体的差异大，有较多的位点频率发生变化。

The results of catalytic activity show that both Ni-B and Ni-P sample have the same kinetic equation for hydrogenation of 1, 3-cyclopentadiene to cyclopentene and the same TOF. Therefore, it can be suggested that they have the similar active site. The catalytic activity of Ni-B sample is higher than that of Ni-P sample, and it is due to the more active sites of Ni-B sample having.

催化活性测试表明，Ni-B与Ni-P催化环戊二烯加氢反应对环戊二烯具有相同的动力学方程，而且两者具有相似的氢转换频率，表明两者的活性中心本质上是相似的，类金属不同导致的电子转移方向的不同仅仅影响反应的初活性，宏观活性的差别在于两者活性中心数量的不同。

This thesis studies the volcanic tectono-petrofacies, petrology, mineralogy, geochemistry, isotopic chronology, stratum and high-precision SHRIMP zircon U-Pb datings of the Mt.Yandangshan volcano-intrusive complex, and concludes that: Yandangshan volcanic rock units belong to high-K calc-alkaline acid rock associations, mainly ryholitic and trachytic dacitic in composition. They have A/CNK values of 0.9-1.2 (i.e., aluminium saturation and supersaturation), enriched LREE and LILEs and depleted HFSE. Their 8Eu values are 0.11-0.32, indicating a evident fractional evolution of plagioclase crystallization. Their ∑REE varied very limitedly,(87~Sr/(86)Sri ratios and eNd values are 0.7086～0.7095 and -10.20～-9.96 for volcanic rocks, and 0.7087~0.7095 and -7.6～6.92 for the central intrusive facies syenite, which means that all the igneous rocks from Mt. Yandangshan are evolutional products of magmas with the same source, and that they derived mainly from crust, but mixed with mantle components.

本文从火山构造岩相学、岩石学、矿物学、地球化学、同位素年代学、地层学等方面出发，同时结合高精度SHRIMP锆石U-Pb定年，对雁荡山火山岩进行了系统的研究，确定雁荡山火山岩为一套以流纹质和粗面英安质为主体的高钾钙碱性酸性岩石组合，A/CNK值集中在0.9～1.2之间，为铝饱和或铝过饱和类型；富轻稀土元素和大阳离子亲石元素、相对亏损高场强元素：负铕异常明显，δEu值为0.11～0.32，表明岩浆经历了以斜长石为主的强烈结晶分异作用：岩石样品的∑REE变化有限，火山岩样品的~(87Sr/~(86)Sr_i为0.7086～0.7095，εNd为-10.20～-9.96，中央侵入体石英正长岩~(87Sr/~(86)Sr_i为0.7087～0.7095，εNd为-7.6～-6.92，表明它们是同源岩浆分异演化的产物，物质来源主要为陆壳，但有地幔物质参与。

The RT-PCR product was inserted into pTG19-T vector and transformed into E. coli successfully. By blastn, the sequence results of Kunming mus musculus were in complete accordance with the conservative sequence of Genbank NR_003278 (791bp-1153bp). By Blastn in NCBI, the sequence with little difference among animals was confirmed to be conservative. After Blastn, fourteen complete CDS coding for different animals were chosen. According to VECTOR NIT 9.0 software, the similarities between Kunming mus musculus and bos taurus, homo sapiens, erinaceus europaeus, cricetulus griseus, sus scrofa, dasypus novemcinctus, rattus norvegicus, rabbit, equus caballus, macaca fascicularis, didelphis virginiana, monodelphis domestica and vombatus ursinus was 67%, 100%, 100%, 36%, 100%, 100%, 67%, 100%, 100%, 92%, 99%, 99% and 99%. In the phylogenetic tress constructed with the forteen 18S rRNA by Treeview, the Kunming mus musculus clustered with cricetulus griseus, sus scrofa and rabbit, which was nearer to cricetulus griseus and was most far away from macaca fascicularis.(3) After sencodary structure analyses of 18S rRNA of mus musculus, an oligonucleotide fragment for RNAi was designed and synthesized, which was transformed into plasmid, and restriction enzyme analyses and sequencing results should the expression plasmid pGPH1/ GFP/Neo-mouse-sh 18S rRNA were constructed for RNAi successfully.
