The experiments show that TiO〓 nanowire arrays have higher photodecomposition efficiency than TiO〓 film. It is due to not only their higher surface area, but also their wider energy gap. 6. Ordered NiO nanowire arrays embedded in anodic alumina membranes have been prepared by using an electrochemical deposition method. Thermogravimetry curve shows that NiOH embedded in AAO decomposed slowly compared to thin film.

可能存在两个原因：氧化钛纳米丝具有比氧化钛纳米膜更大的比表面积；氧化钛纳米丝的光学带隙大于氧化钛纳米膜的，带宽的增加，使得价带电子电位变得更正，导带电位变得更负，这实际上增加了光生电子和空穴的氧化还原能力，提高了半导体光催化氧化有机物的活性。

It includes the following steps: extract trivalent iron ion and divalent iron ion in water phase through organic extractant, get predecessor of; absterge it with secondary distilled water for2-3 times and get pure load metal predecessor of organic phase; mix organic phase of Mg2 and Fe3 with mol rate of 1:2 and introduce them into autoclave, add distilled water according to the rate of 3:1 or 4:1 of organic phase and water phase and airproof it, and then mix it fiercely, stripping with hydrothermal method at temperature between 200 degree C and 300 degree C and make them react for 2.5 hours; cool it to the room temperature under natural condition, separate liquid and centrifugalize it, absterge it with absolute alcohol for 2-3 times and dry it at temperature of 50 degree C for 30-180 minutes, then get product of magnesium ferrite.

包括如下步骤：通过有机萃取剂来萃取水相中的三价铁离子和二价镁离子，制得有机相前驱物；用二次蒸馏水洗涤2-3次，获得纯净的负载金属有机相前驱物；按照Mg 2 和Fe 3 摩尔比1∶2将有机相混合均匀后引入高压釜中，按照有机相与水相的比例为3∶1或4∶1加入蒸馏水，密封后，对溶液进行强力搅拌，水热反萃的温度在200-300℃之间反应2.5小时；自然冷却至室温，分液，离心分离，用无水乙醇洗涤2-3次，在50℃下干燥30-180分钟，得铁酸镁产品。

它们在减数分裂时的单价体数目比三倍体显著地减少了，但另外却有少量三价体和四价体出现。

ABSTRACT The final production of erythromycin by Saccharopolyspora erythraea was increased by 43.1% in 15L bioreactor with double quantily of soybean oil into culture medium. The final production, production capacity and Yp/s of erythromycin were improved 69.7%, 69.6% and 63.8%, respectively, in 15L bioreactor with added soybean oil during fermentation.

红色糖多孢菌D在15L发酵罐的基础培养基和发酵过程中补加豆油，当基础培养基中豆油量加倍时，效价提高43.1%；发酵过程补加豆油罐的红霉素效价、生产强度和Yp/s比不补豆油的分别提高了69.7%、69.6%和63.8%。

The results showed: 1 RN didn't the leaf width,leaf long,leaf area,yield,productive value and average price of flue-cured tobacco,but had significant effect on grad composing,content of chemical component and the accumulation of N,K and Cl.Within limited rang of RN,the relations between yield,average price,yield of high grad tobacco,yield of low grad tobacco,nicotin,N,reducing sugar,Cl,amylum,volatile base and the quotient of ammonium would been described by significant quadratic polynomial,and the relations between K and the quotient of ammonium conformed to negative linear equation;2With a RN of 75%∶25%,the value of proportion of high and middle grad tobacco,content of nicotin,N,K,uptake of N and K/Cl were the highest,volatile base was lowest.

结果表明：1RN对烤烟的农艺性状、产量、产值、均价等没有明显影响，而对烤烟的等级结构、内在化学成分含量、氮、钾、氯的吸收量有着显著影响，可以用显著的二次多项式模型或直线相关方程描述产值、均价、上等烟产量、下等烟产量等经济性状以及烟碱、总氮、钾、还原糖、氯、淀粉、挥发碱等内在化学成分的含量与铵态氮份额之间的关系；2RN为75%∶25%时，中上等烟比例、烟碱、总氮、钾、钾氯比、氮吸收量最高，挥发碱含量最低。

The results show: the new schedule was simple, easy-running, and the Quality of cured tobacco was improved: rates of orange tobacco, the first class tobacco higher than check by 3.38, 4.74percentage, average price is 01.53 yuan/kg higher. Meanwhile, total sugar, starch, nicotine, total nitrogen, protein and the difference between total sugar and reduce sugar is lower, and chemical composition is more balance than check.

结果表明：设置的烘烤工艺阶段简单，操作方便，烟叶烘烤后，比三阶段烘烤工艺烘烤的烟叶桔黄烟比例、上等烟比例、上中等烟比例分别增3.38、4.74、2.03个百分点，鲜干比增高0.03，均价提高0.53元/kg；总糖、淀粉、总氮、烟碱、烟碱氮、蛋白质的含量及总糖与还原糖的差值有所降低，烟叶化学成分更为协调。

In terms of the obtained values of parameters, it is demonstrated that the covalency of the bonding between Mn〓 and ligands in SrTiO〓: Mn〓 is stronger than the one of the bonding between Cr〓 and ligands in SrTiO〓: Cr〓.

通过分析得到的常压参量值，揭示了在SrTiO〓：Mn〓中Mn〓与配位体之间的共价作用比SrTiO〓：Cr〓中Cr〓与配位体之间的共价作用更强。

In addition, the city of goods traded last week an average price of residential 16,431 yuan / square meters, over the previous week rose 24 percent, mainly as a result of the Center City District traded rebound between the high-end properties in the outer ring purchase from pre-wait-and-see to the current buyers to enter the practical stage, and the external high-end villa such as "Shimao Hill" and "Palm Beach" of the transaction, last week pushed up the city's average commercial housing transactions.

此外，全市商品住宅上周成交均价为16431元/平方米，比前一周上涨了24%，这主要由于中心城区的成交回升，中外环间高端物业购房者从前期的观望到目前进入实际的购房阶段，以及外围高端别墅如&世茂山庄&和&棕榈滩&的成交，拉高了上周全市商品住宅的成交均价。

Some ratio plays have fetched hefty gains in the past. In Feb. 2003, the gold-silver ratio spiked to 80, which heralded silver's one-year ride from less than $5 a troy ounce to above $8 in April 2004 — a 60% return.

一些依靠此类比值进行的交易曾在过去创造过丰厚的回报。2003年2月，黄金/白银价格比突破80倍，由此吹响了银价上攻的号角，在每盎司不到5美元价位徘徊一年之后，银价到次年4月突破了8美元，回报率达60%。
