蒸发

Based on theoretical analysis and model experiment, design of open channel rotor is presented in the paper. The following is included: overall design of system, coolant feed and discharger beside the axis, design of rotor winding, overflow, steam exhausting way in the channel and so on.

论文在理论分析和模型实验的基础上设计了开放管道式蒸发冷却转子方案，其中包括：整体结构设计、轴边进液和余液排出装置、转子线圈结构设计、溢流装置设计和槽内排汽孔方案设计等。

When the soil surface is fully mulched with plastic film, salt concentration is a exponential function of depths. With different film hole ratios and wetting fronts depths, the salt concentrations can be expressed as a discontinuous function of the depth.

对不同开孔率来说，全覆膜蒸发的浓度可用深度的指数形式表达，不同入渗锋和开孔率条件下浓度可表示为位置的分段指数函数。

结果表明，在环境相对湿度为70%～80%时，于柜内蒸发水与否，对杀菌效果崐无明显影响（表4）。

Then,the tradition manner of crystallization was evaporating and crystalline,but this paper made the other method . The salt-mixture solution of the disodium hydrogen phosphate and the monometallic odium orthophosphate was put in ethanol.

传统的结晶方法是通过加热蒸发结晶，而本文则采用了一种新的结晶方法，在精调后的正磷酸盐混合溶液中加入乙醇，由于正磷酸盐不溶于乙醇，就会使正磷酸盐溶液达到过饱和，再通过搅拌，析出晶体。

This implies that the dolomitization of the oolitic limestone took place in the early stage of diagenesis, and was possibly influenced by mixing rain water and evaporated seawater.

白云石化由层间古暴露面向下增强的成岩层序说明这种白云石化是成岩早期发生的，并可能有大气降水与蒸发海水混合的影响。

However,very low Mn contents(average 19.8ppm),relatively high Sr contents(average 137ppm)and the homogenization temperatures measured in fluid inclusions of crystalline dolomite do not support the hypothesis that meteoric water as high as 94% involved the dolomitization.

但极低的锰含量、相对较高的锶含量和包裹体均一化温度等资料均不支持有94%的大气淡水参与了结晶白云岩的白云石化作用，其白云石化流体应是埋藏成岩过程中囚禁的近同期、但是非同期的海源流体，其来源可能与埋藏成岩过程中该时间段蒸发盐的溶解有关。

The new sieve tray tower of carrier gas evaporation can be installed with multiplayer sieve trays, and has double concentration ratio as compared with that of general sieve tray towers, and can be operated under vacuum conditions, which can avoid the leakage of acrylamide.

依据新方法开发的新型载气蒸发筛板塔可采用多层塔板操作，该塔与未设置加热管且塔板较少的情况相比，浓缩比可以提高1倍；采用负压操作，可以避免丙烯酰胺泄漏。

Wavy distribution of soil water along hillslope resulted from the fluctuation of runoff, upslope runoff infiltration, lateral downslope flow, and the difference of infiltration rate and evapotranspiration.

4土壤水分沿坡面呈"波浪形"分布是坡面径流的波动性、上方来水的沿程入渗、侧向沿坡向下流以及坡面各处入渗性能和蒸发蒸腾作用的差异等综合作用的结果。

Finally, two short-path distillation processes and one falling film evaporator are applied in the regeneration of waste lubricating oil. In the test, the diesel oil, gasoline and lubricating oil are distilled respectively, while the gelatinoid materials, asphaltene and carbon residue remain in the draft. The regenerative lubricating oil accords with the standards of base oil. And the recovery efficiency is up to 75 percent. The technology used in the test doesnt comprise processes like pickling and alkali neutralization, which would cause secondary pollution like acid draff and sulfur dioxide and so on. As a result of this, our technology is friendly to the environment.

最后，利用一级薄膜蒸发和两级短程蒸馏工艺对废润滑油进行了再生回收工业应用试验，将柴油、汽油等轻油以及润滑油馏分分别蒸馏出来，而大部分胶质、沥青质、碳垢存在于残渣中，试验得到的再生润滑油符合基础油的标准，回收率达到75％，达到废润滑油再生的目的；同时再生过程中没有酸洗、碱中和等工序，不产生酸渣、二氧化硫等二次污染，是一种清洁环保的废润滑油再生工艺。

The appropriate dripper discharge should be selected for different soil texture and climatic conditions. In this paper, the laws of soil moisture distribution and soil evaporation in different dripper discharges were researched.

本文研究了干旱区不同的滴头流量下土壤水分再分布及土壤蒸发的变化规律，结果表明，地表湿润圈的大小直接影响到蒸发量的大小。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
