前驱

The main work as follow: 1. The precursor of W-Cu composite powders was prepared by chemical coprecipitation using tungstenic acid and chalcanthite.

以黄钨酸和五水硫酸铜为原料，用化学共沉淀法制备钨铜复合粉前驱体粉。

Surveillance: routine follow-up in a metabolic clinic; monitoring for hyperammonemia and secondary deficiency of essential amino acids; monitoring older individuals for signs of impending hyperammonia (i.e., mood changes, headache, lethargy, nausea, vomiting, refusal to feed, ankle clonus) and elevated plasma glutamine concentration.

监控：在代谢诊所里日常的随访；监测高血氨和必须氨基酸的并发性缺乏；监测较年长患者的高血氨前驱期症状（例如情绪改变、头痛、嗜眠、恶心、呕吐、拒绝进食、脚踝阵挛）和升高的血浆谷氨酰胺。

The hexagonal close-packed Ni nanoparticles were synthesized with the precursor prepared by sol-gel method via heat-treating technique in Ar atmosphere.

采用溶胶－凝胶方法制备前驱体样品，在氩气气氛中不同温度下热处理得到样品。

Photocatalytic degradation experiments for cokery waster water were carried out using thefilms.

以四氯化钛乙醇溶液为前驱体，采用溶胶——凝胶法在普通的玻璃管上制备了掺铈TiO_2纳米膜，并用此薄膜作了焦化厂废水光催化降解实验，得出了该光催化降解反应的有利条件。

On the basis of these, the effect of acid concentration on catalyst behaviors was emphatically studied.

并在此基础上，集中探讨了前驱体制备过程中，滴加的酸浓度对催化剂性能的影响。

The results showed that coniferin could completely polymerize with model compound of β-O-4 type lignin to form lignin macromolecule. The M of the polymerized product was much higher than the starting materials.

研究表明：在漆酶的催化作用下木质素前驱物松柏醇－β-D-葡萄糖苷与木质素模型物能很完全的发生聚合，产物中不存在起始物的晶体，M也大大的增加了。

The polymerization reaction between coniferin and soluble lignin in the effluents from paper mill, catalyzed by lignin oxidase, was investigated.

研究了在木素氧化酶催化的体系下，木素前驱物松柏醇-β-D-葡萄糖苷-[α-13C]与废水中可溶性木素的聚合反应方法。

X-ray diffraction shows that the synthesis of cordierite and in situ nitridation of TiO2 were fulfilled simultaneously.

不同温度下合成产物的X射线衍射分析表明：前驱粉体在1250℃氮化3h时，堇青石与氮化钛的合成反应能同时完成。

I have shown a dog with a beautiful shoulder almost 90 degrees but he could not move very well tho he looked great in the stack.

我展示过一条非常漂亮的前驱的狗，他接近90度，但是他的动态并没有和他的静态一样表现得非常完美。

NOW the bright morning Star, Dayes harbinger, Comes dancing from the East, and leads with her The Flowry May, who from her green lap throws The yellow Cowslip, and the pale Primrose.

五月晨歌晶莹的晨星，白日的前驱，她舞蹈着从东方带来娇侣，百花的五月，从绿色的怀中撒下金黄色的九轮花和淡红的樱草花。

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。
