前驱

The nano-β-FeOOH for precursor of γ-Fe2O3 was synthesized by microemulsion method, then the β-FeOOH was calcined by mixing with additive polyoxyethylene nonyl phenyl ether (NP-4) in the molar ratio of β-FeOOH/NP-4 as 4, 5 and 100 respectively.

采用微乳法合成出氧化铁的前驱体－纳米β-FeOOH，分别以β-FeOOH与添加剂壬基酚聚氧乙烯醚(NP-4)以物质量的比为4， 5， 100添加NP-4，混合锻烧。

The price of this kind of life is all efforts necessary to maintain American interests, including letting the silly House of Saud rule over that prosperous nation, and keeping despots like Suharto, Noriega and Saddam who serve America in place, this is also true.

这种生活的代价是全力维护美国的利益，包括让愚蠢的沙特王室继续统治这个富裕的国家，让苏哈托、诺列加、萨达姆这样的暴君存在，为美国效力充当前驱。这也是真的。

A general Godunov finite difference schemes-WENO (Weighted Essentially Non-Oscillatory) schemes which have fifth-order accuracy is used to perform a numerical calculation for 2-dimensional axis symmetrical laser-supported plasma flow field under laser ablated solid target.

采用具有五阶精度的WENO差分格式和简易等离子体状态方程模型对激光与等离子体相互作用的复杂物理过程进行了数值计算，分析了激光束能量在等离子体区中的吸收、屏蔽效应等动态耦合规律以及激光支持等离子体前驱冲击波传播。

Secondly, opaline photonic balls which are narrow dispersed in size and in the range of a few or tens micrometers in diameter, were fabricated using monodisperse polystyrene latex particles.

第三，利用聚合物乳胶粒子形成的蛋白石结构的胶体晶体和光子球作模板，通过渗入二氧化钛前驱体，成功制备出以二氧化钛为骨架的，有序大孔反蛋白石结构的光子晶体和光子球。

Forequarters:前驱 The shoulders are long and well angulated to the upper arm, neither in nor out at the elbow.

肩与前腿成角度，肩需与肘关节在一条直线上。

The results with DTA show that freewater, PEG, Hac and n-C4H9OH evaporate under 320℃. Organic compounds oxidate and precursors of the samples decoposite between 320~500℃.

热分析结果表明：样品在320℃以下有自由水、PEG、HAc、n-C4H9OH的挥发，而在320~500℃之间样品中的有机物发生氧化反应和前驱体发生分解反应。

Since completing this pilot study, they have carried out a study in multiple sclerosis patients with similar results, Dr. Penner noted. Currently, they are running a study in patients with schizophrenia.

Penner博士指出，完成此前驱研究之后，他们在多发性硬化症病患进行此类似研究，也有类似结果；目前，他们正对精神分裂病患进行类似的研究。

To realize our goal, two kinds of vanadium source, including amorphous vanadium pentoxide, and the intermediate in the process of forming vanadium pentoxide gels, were used as precursors in this study.

于是，我们在研究中使用了两种钒源用作反应前驱体（一种是无定形的V2O5粉末，另一种是H2O2处理V2O5形成溶胶过程的中间体），选取了多碳醇与烷基链相同的单胺两种结构导向剂。

Taking Na_2SnO_3·3H_2O as raw material, organic reagent (pentyl alcohol, butyl alcohol, cyclohexane) as dispersant, and adding anion surfactant (sodium dodecyl alkylbenzen sulfonate, ABS), uniform ultrafine SnO_2 powder is prepared by hydrothermal method using Sn_4 deposition as precursor.

以Na2SnO3·3H2O为原料，有机试剂(正戊醇、正丁醇、环己烷)为分散剂，同时加入阴离子表面活性剂(十二烷基苯磺酸钠，ABS)，以氢氧化锡沉淀为前驱体，用水热法制备了粒度均匀的SnO2超细粉体。

During the process of peptization and hydrothermal crystallization, the aggregation behavior and the resulting morphology of nanocrystalline titania (TiO2) were studied by X-ray diffraction, scanning electron microscope, and dynamic light scattering techniques.

通过XRD、SEM和动态光散射粒度测定仪研究了胶溶及水热晶化过程中纳米TiO2晶粒聚集行为及形貌。实验结果表明，在胶溶无定形沉淀过程中所形成的大小为10-15nm的锐钛矿型胶粒或金红石型胶粒易定向聚集成更大的、具有(30-50)nm×(80-100)nm的次级晶粒。含有次级晶粒的溶胶前驱液在水热晶化过程中，次级晶粒发生崩裂并生长成结晶度更高的大小约为10-30nm球形和大小约为20-60nm棒状纳米TiO2

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
