乙烯醇

Indium Tin Oxide nano-powder was prepared with a convenient solvent thermal method. A hydroxide precursor was first prepared from indium chloride and tin chloride by using ammonia as precipitating agent.

以氯化铟和氯化锡为原料，氨水为沉淀剂，先用化学沉淀法制备了前驱体，然后将该前驱体以乙二醇为溶剂在聚四氟乙烯内衬的反应釜中于低至190 ℃下反应，获得了铟锡氧化物纳米粉体。

Polyvinyl alcohol has been used industrially as a dispersant in the synthesis of the polymer emulsions of vinyl acetate.

聚乙烯醇已用于工业作为分散剂在合成聚合物乳液醋酸乙烯酯。

N-Butyl acetate was synthesized from acetic acid and n-butanol using polyvinyl chloride-polythylene polyamine resin which adsorb s metal ions as the catalyst.

采用吸附了金属离子的聚氯乙烯—多乙烯多胺树脂为催化剂，乙酸和正丁醇为原料催化合成了乙酸正丁酯。

However, because they are rapidly metabolised, a normal osmolal gap does not rule out ethylene glycol or methanol poisoning s.

可是，由于这些物质很快被代谢，因此血渗透压间隙水平的正常并不能排除乙烯乙二醇或甲醇中毒。

However, because they are rapidly metabolised, a normal osmolal gap doe s not rule out ethylene glycol or methanol poisonings.

可是，由于这些物质很快被代谢，因此血渗透压间隙水平的正常并不能排除乙烯乙二醇或甲醇中毒。

In the course of educational experiment on the synthesis of non-ionic surfactant, in order to reduce the depletion on ethylene oxide and save experimental cost, an educational experimental device with the function of enduring highpressure and little reaction mass was constructed by refitting a 250mL high-pressure reactor. In order to verify the function of the experimental device, lauryl alcohol polyoxyethylene ether was synthesized by it.

在非离子表面活性剂的合成教学实验中，为了减少环氧乙烷的消耗，节约实验成本，对250mL的高压反应釜进行了改造，筹建了一套耐高压反应物料量少的教学实验装置，并用此装置合成了十二醇聚氧乙烯醚，以验证此装置的性能。

Blood level s for methanol and ethylene glycol are not usually reported quickly.

血液中甲醇和乙烯乙二醇的水平通常不能很快测出。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
