查询词典 condensation

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

It was indicated by UV-Vis spectra characterization that the precursor always contains the tetrahedral Ti species and the octahedral Ti species regardless of the Ti content. Calcination of the precursor resulted in a partial condensation of the octahedral Ti species to form the anatase phase.

UV-Vis 光谱表明，Ti-MWW 合成原粉中含有四面体的钛和八面体的钛，而八面体的钛属于一种骨架外钛，未经酸处理而煅烧会使部分八面体钛缩合形成锐钛矿，而经过酸处理和煅烧后的分子筛则几乎不含有锐钛矿。

If the baby wake up 6:00 every day, can be fed egg share, 9:00 breastfeeding, 10:00 Hey some fruit, porridge or noodles 12:00 Hey, with a small amount of vegetables and meat, bean food, in the absence of calcium, bones can be used to the baby soup to eat the following article by : with fresh boiled bones plus open to offscum write clean, modest Add vinegar, and promote the dissolution of calcium, small火煮2 hours,放冰箱refrigerated cooling box 2 hours, which the oil will float on the surface of condensation to skim the oil, and then冻成Xiaobing pieces, cooking time can come up with a few feeding .15:00, 18:00 feeding porridge,临睡前re-feeding.

如果孩子每天6：00醒，可以喂鸡蛋羹，9：00喂奶，10：00喂一些水果，12：00喂粥或面条，内加蔬菜和少量肉，豆腐类食物，如果没有补钙，可用骨头汤下面条给孩子吃，方法是：用新鲜的骨头加水煮开，把浮沫撇干净，放入适量米醋，促进钙的溶出，小火煮两个小时，放冰箱冷藏箱里冷却两个小时，里面的油会凝结浮在表面，把油撇去，然后冻成小冰块儿，煮面的时候拿出几块即可。15：00喂奶，18：00喂粥，临睡前再喂奶。

The proposed method has the capability of predicting the performance of condenser including threedimensional effects due to the change of cooling water temperature and the multiple tube paths arrangement. The proposed algorithm is more suitable to the condenser of multiple tube-paths than existing method. The proposed method is applied to a N11220-1 condenser to demonstrate its predictive capability, the results indicate that condensation rate of each bay and the air concentration at gas offtake is quite different, which can not be predicted by two-dimensional method.

对N11220-1型凝汽器的一个实验工况的模拟表明，该方法的热流密度计算结果与实验结果吻合良好，证明方法是有效的，模拟结果还表明，由于冷却水温度沿程变化，沿轴向各个汽室的冷凝量和抽气口的空气浓度均有明显不同，而目前国内外仍在使用的二维模型程序无法考虑这些影响，计算精度较差。
