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。

Findings suggest that rostral neuro-structures do exert tonic influence on medulla vasomotor functions.

以上发现显示：吻端的神经结构对於延脑管制血管舒缩的功能，会发挥紧张性的影响。

To predict sandfish swimming speed, we developed an empirical model by measuring granular drag force on a small cylinder oriented at different angles relative to the displacement direction and summing these forces over the animal movement profile.

据美国《Science》杂志线上新闻报导，高速 X 射线成像结果显示，这种蜥蜴会缩拢它们的四肢，并通过Z字型地左右摇摆身体来推动自己在沙子上前进，其像鱼或蛇一样摆动身体前行的速度能够达到每秒钟15厘米。

Further studies showed some DH plants could generate two or more than two stems in which wrinkledness mutant and wild types except for the leaf wrinkledness, therefore they were the better materials for studying the wrinkledness characteristic. The finding is useful in studying, locating and cloning the wrinkledness gene linked to leaf mutants of Brassica allosextuple CGMCC № 2553 DH lines in the future.

进一步研究发现，在同一DH再生植株上常常会萌发出皱缩和野生型的2个或多个分枝，由于皱缩和野生型除了叶片皱缩性状不同外，其他性状完全相同，因此叶片突变体和野生型是研究叶片皱缩性状的理想材料，有利于进一步研究皱缩基因的遗传，定位、克隆叶片皱缩相关基因。

In this example, the selector matches any p element that is the first child of a div element , and indents the first paragraph inside a div element

在这个例子中，选择器匹配任何一个在DIV元素中第一个P子元素，而且它的首个段落会缩进

Contractions hurt, but not like stubbing your toe or having an earache.

宫缩会疼的，但不像脚趾头被碰或耳朵发炎那种疼。

But it also might err by withdrawing reserves too quickly, thereby stunting the recovery and leading to deflation.

如果矫枉过正，过于迅速的收回，则会有延缓经济复苏和通缩的风险。

A muxing window will open when you press Queue.

当你点击Queue时，一个混缩的窗口将会弹出来。

And you'll be presented with thumbnails of your photos.

你会提交的缩略图您的照片。

The result shows that, when a free droplet transfer mode is applied in high-speed welding , the workpiece is heated by the arc throughout the process and thus the molten pool can not solidify in time.As a result, the molten pool is very long, which gives way to the instability of bead formareron and pinch effect of the liquid metal,so that it finally leads to the humping phenomenon. Based on the analysis and experimental result, the short-circuiting transfer mode is suggested to improve the bead formation in high-speed welding .

理论分析和试验结果均表明，采用自由过渡的熔滴过渡形式进行焊接，工件始终处于焊接电弧的加热下，在高速焊接时，熔池不能及时冷却，熔池明显拉长，由扰动引起的振动波长大，当熔池的拉长达到一定程度时，会发生液体金属的失稳和颈缩的现象，造成驼峰焊道。
