The invention adopts surfactant of amphipathic block copolymer as structure-directing agent to be dissolved in alcohol solvent, and niobium sources and aqueous solution of inorganic salts are added as structural promoter to be stirred for a certain period of time in the room temperature to form colloid; the colloid is then heated and volatilized under low temperature to remove the solvent and dried and calcined under high temperature to obtain the mesoporous columbium oxide.

本发明将双亲性嵌段高分子表面活性剂作为结构导向剂溶解于醇类溶剂中，加入铌源和无机盐类水溶液作为结构促进剂，在室温下搅拌一段时间后形成胶体，低温下加热挥发除去溶剂，经干燥、高温焙烧而成。

The simulation floating zone modelwith zero temperature gradient in the middle of the hot rod is proposed to simulate thehalf part of the full floating zone convection,since the temperature gradient in the middleof a full floating zone approaches zero.

根据加热方式的不同，可以将半浮区液桥分为通常半浮区液桥模型、模拟半浮区模型以及改型半浮区模型。通常半浮区液桥模型，液桥热端材料一般选择为金属材料，使得热端温度分布均匀。液桥产生热毛细对流时，在液桥热端内侧存在较大的轴向温度梯度。而在全浮区热毛细对流中，浮区中间的轴向温度梯度在对称条件下应该接近于零。

Moreover, the pre-treatment and post-treatment processes for the steel sheet subject to continuous zinc plating were also discussed. Results showed that the alkaline zincate plating process had many advantages over conventional alkaline cyanide zinc plating process, including high current efficiency, good throwing power, and strung adhesion strength of the coating.

结果表明，该工艺电流效率高（锌离子含量16~24g/L时，电流效率可提高约20%，镀液均镀能力好（宽度为1m的镀锌薄板，中心点厚度与边缘厚度差不大于10%，镀层结合力优良（将试片180°任意弯曲，镀层无起皮、剥落现象；在烘箱中加热至180-200℃，保温60min，冷水中急剧冷却，镀层无突起、鼓泡、剥落现象），所镀得的镀锌薄钢板适合于钝化和彩涂等后处理。

Then,the tradition manner of crystallization was evaporating and crystalline,but this paper made the other method . The salt-mixture solution of the disodium hydrogen phosphate and the monometallic odium orthophosphate was put in ethanol.

传统的结晶方法是通过加热蒸发结晶，而本文则采用了一种新的结晶方法，在精调后的正磷酸盐混合溶液中加入乙醇，由于正磷酸盐不溶于乙醇，就会使正磷酸盐溶液达到过饱和，再通过搅拌，析出晶体。

We have always committed to the world's most advanced electromagnetic heating technology.

By an argon flow where its condensation occurs while being cooled. The analyte containing aerosol particulates can then be quantitatively re-collected by means of intra-furnace electrostatic precipitation on the wall of a graphite tube , or by external EP on a secondary graphite boat or onto one or a set of secondaryplatforms by means of corona discharge applied to the deposition site .In comparison with other techniques, the ETV-EP sampling offers some essential advantages.

在这种情况下，样品矩阵的大部分被加热分解首先去除，那么analyte 被汽化在熔炉和失去控制由它的结露发生的氩流程当冷却。analyte包含湿剂微粒物质可能定量地然后被回忆通过内部熔炉静电降雨雪在石墨管的墙壁上，或由external EP 在一条次要石墨小船或一个或一套次要平台通过光环放电适用了于证言站点。

The experimental results were compared with those obtained by traditional methods of water _ bath heating saponification and enzymology _ spectrophotometry.

目前采用最多的皂化方法是将待测物与KOH的甲醇溶液加热回流1 h[ 3]，但由于其耗时长，不适应于大量样品的测定。
