I also added a couple of spaces for indentation to the contents to make them easier to read.

我还增加了为缩进的内容空间夫妇，使它们更易于阅读。

The experiment results indicate that: the increases of catalyst concentration, feed mole ratio of methanol to formaldehyde and the decrease of total feed flow can increase the yield of methylal; the concentration of methylal in distillate also increases with the increase of catalyst concentration; that the effects of reflux ratio on the yield and concentration of methylal in distillate are different from conventional distillation process, an optimal value of reflux ratio exists between 1 and 2 for this process.

实验结果表明：回流比对甲缩醛收率和塔顶甲缩醛纯度的影响不同于一般的精馏过程，存在一个最优回流比，本过程最佳回流比在1-2之间；提高催化剂浓度，甲缩醛收率和塔顶甲缩醛纯度均增加；提高进料醇醛摩尔比也会提高甲缩醛收率；进料总流量对甲缩醛的收率的影响十分明显，进料总流量减少可以使甲缩醛的收率得到明显提高。

Limber hip joints let you scrunch up close to the rock and get right under tiny edges and slopers that would be impossible to hold if your body weight were away from the rock. Hip flexibility opens up more opportunities for stemming and resting, too.

柔软臀部关节可以让你在小的岩角或较斜的地方更能缩进岩壁，如果你的重心离开太远便抓不住；臀部的柔软同样的可以使支撑及休息有更多的选择。

The film can keep freshness of food, prevent the loss in quantity, dry and taste mixing, and be safe and hygiene.

缠绕膜具有良好的回缩记忆及自粘性，能使货物紧裹成一个整体，防止运输进闪落倒塌及灰尘污染，并且该膜还具有优良的透明度和延伸性，能使包装物品美观大方，经济实用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
