In general, TiO2 synthesis used precursors for the titanium alkoxide or titanium metal salt which are hydrolyzed and thermal treatment to obtain TiO2 crystals.

传统二氧化钛合成是利用含钛的金属烷氧化物或含钛的金属盐类为前驱体，加以水解及热处理。

The sol's sensitivity towater can be improved by using inorganic salts instead of alkoxide as bismuthand strontium precursors, and hence the sol-gel processing can be simplified.

用无机盐代替醇盐作为锶和铋的前驱体，可克服溶胶对空气中水分的敏感性，从而大大简化了SBT薄膜的制备工艺。

The precursor solutions of titanium alkoxide with different amount of AcAc were characterized by DTA to study the chelating process of titanium alkoxide with AcAc.

对含有不同量乙酰丙酮的前驱体溶液做了热重分析，研究了钛酸丁酯与乙酰丙酮的螯合过程。

It is possible that atypical perilobular hemangiomas or atypical hemangiomas are precursors to angiosarcoma, but this relationship remains to be demonstrated.

不典型小叶周围血管瘤或不典型血管瘤可能是血管肉瘤的前驱病变，但这种相关性尚需要进一步证实。

Different from conventional fabrication of cathode powder, non-chelating polymer polvinyl alcohol serves to sterically entrap the metal cationa in a manner thewey which facilitates the formation of an atomistically homogeneous precursor material. And, calcining the solid precursor material to form a mixed metal oxide material, that is perovskite structured powder La0.5Sr0.2Co0.5Fe0.5O3.

该方法与传统方法不同，采用非螯合聚合物－聚乙烯醇(PVA， Polvinyl alcohol)作为阳离子的载体，形成含有La(上标 3+)，Sr(上标 2+)，Co(上标2+)，Fe(上标 3+) 4种金属阳离子和非螯合聚合物的均匀溶胶，干燥生成固体凝胶状前驱体。

Its precursor is Aurichalcite. Cu〓 reducted from the precursor exists the micro-crystal and ZnO provides large surface area for Cu〓.

作者认为：该催化剂的前驱体是绿铜锌矿，还原而成的Cu〓以微晶的形式存在，ZnO为Cu〓提供较大的表面积。

The degree of substitution between Cu(superscript 2+) and Zn(superscript 2+) is increased with increasing Cu(superscript 2+)/Zn(superscript 2+) entering crystal lattices of Zn5(CO3)26/Cu2(CO3)2, and the ratio of copper to zinc in Rosasite and Aurichalcite is unchangeable.

随着Cu(上标 2+)/Zn(上标 2+)进入Zn5(CO3)26/Cu2CO32晶格，离子同晶取代量增加，催化剂前驱体中形成了固定铜锌比的锌孔雀石和绿铜锌矿物相。

I will endeavour to find you some assistance.

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。
