Internal Vaporizer (1): This is an internal heat exchanger that functions as a gas vaporizing coil to convert liquid product to gas.

内部蒸发器（1）：这是一个内部热交换器，它作为一个气体蒸发蛇管发挥作用，把液体产品转换成气体。

To control the ground-water table on irrigated lands is vitally important in arid and semi-arid regions. In order to determine the standard of water table control, considerable attentions were paid to the "critical depth"(or "safe depth") of ground-water table. The salts accumulate in the top soil if the water table is not deeper than this depth. The conditions that the salts accumulate in any layer of the soil owing to the movement of soil moisture are:(1) the supplement of soil moisture from neighboring...

本文分析了地下水补給情况下土壤水分的形态和不同形态的水分在土壤中运行和蒸发的一些特点，论証了毛管水联系破裂含水率等土壤水分形态指标与土壤水分运动和土壤积盐状况的关系，探討了次生盐碱化发生的地下水临界条件，提出了地下水临界深度的确定方法，并且对現有的临界深度的确定方法进行了討论与比較。

Their technology and process is basically similar to that used ethylene, the raw material for the oxygen in the silver catalyst, caused by methane or nitrogen stabilizer, the existence of inhibitors of chloride, ethylene oxide directly generate ethylene oxide and ethylene B N and further to certain substances in water than in the tubular reactor for generating hydration ethylene glycol, ethylene glycol solution through evaporation to mention thick, dehydration, fractionation be ethylene glycol and other by-products.

它们的工艺技术和工艺流程基本上相似，即采用乙烯、氧气为原料，在银催化剂、甲烷或氮气致稳剂、氯化物抑制剂存在下，乙烯直接氧化生成环氧乙烷，环氧乙烷进一步与水以一定物质的量比在管式反应器内进行水合反应生成乙二醇，乙二醇溶液经蒸发提浓、脱水、分馏得到乙二醇及其他副产品。

A sump (226) containing the liquid to be distilled is located at a lower portion of the housing. A rotating element (234) extends into the sump and forces liquid to be distilled up a stationary feed pipe (238) where it is discharged into the evaporating chambers which are open at both their inner and outer ends.

一个盛装要被蒸馏液体的储液槽(226)布置在箱体的底部，一个转动部件(234)延伸进储液槽，将要被蒸馏的液体驱至静止的给液管(238)，液体由此被供入内外端开放的蒸发室。

The final coated particle exiting from the condenser is then introduced into the aerodynamic particle sizer spectrometer or home-built aerosol laser time-of-flight mass spectrometer, and its aerodynamic size directly effects on the matrix to analyte molar ratio, which is very important for MALDI technique.

利用自行研制的蒸发/冷凝实验装置作为基质辅助激光解吸/电离飞行时间质谱仪的特种接口，通过冷凝方式在线添加基质，冷凝管出口处的最终粒子直接引入空气动力学粒径分析仪或自行研制的飞行时间质谱仪，可对实验室产生的生物气溶胶粒子进行实时检测。

Heat transfer will worsen if structure parameters of the spring inserts are not fit. The paper think that the mechanism of heat transfer enhances of the spring inserts is the laminar flow lining is thinner because of librating of the spring inserts, accordingly the part of convection is enhanced. But the part of boil is not influenced.

通过弹簧插入物的各个参数对传热性能的影响分析，认为弹簧插入物对竖管降膜蒸发传热强化的机理主要是弹簧的振动加强了液膜的湍动，减薄了层流内层，从而强化了对流传热分量，但对沸腾传热分量没有影响。

The composition of sodium aluminate solution is very complicated, which contains carbonates, sulphates and so on.

由于铝酸钠溶液成分十分复杂，含有碳酸盐、硫酸盐等多种杂质，在蒸发过程中会以盐类结晶形式析出而附着在换热管壁上形成结疤，进而影响蒸发器的效率和运转率。

Compares the economy of energy and heating charges for two heating seasons in the Kaili Garden, Tianjin, chosen as a pilot project of heating metering, where a calorimeter is installed at each building, a balance valve at each entrance and an evaporative heat meter and a thermal static valve on each radiator in the one-pipe vertical heating system, analyses the existed problems and energy saving potentials both by users' behaviour and by technical measures, considers the heating charging system reform and establishment of related regulations to be urgently needed.

辛坦选择天津凯立花园住宅小区作为热计量试点工程，在单管顺流式热水供暖系统中，每栋楼装一个热能表，每个热力入口装热量调节阀；每个散热器入口装温控阀，散热器上装蒸发式热分配表。对两个供暖季的节能效果与取暖费节省情况进行了对比分析，总结了存在的问题，从行为节能和技术节能的角度指出了节能的潜力，认为尽快将取暖费由暗补变明补、制定热计量收费管理办法是两个亟待解决的问题。

Generally, the multiple - effect vacuum evaporating process is adopted and heat - exchanging equipments are mainly shell and tube exchangers, and stage I always adopts 0.6 MPa new steam as heat source.

在氧化铝的生产过程中，需要保持系统的水平衡和盐平衡，一般采用多效真空蒸发的生产工艺，换热设备大都采用列管式换热器，I效多采用0.6MPa的新蒸汽作为热源。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
