It is foaming in layer gutters when megatemperature frother and nitrogen gas are filling in. HS foam film blanks off high permeability zone or high capacity channel, which represses vapor going into high permeable bed and makes it turning to low ones. Wherefore the displacement volume includes and vapor sweep area expands and reservoir development improves.

通过加入高温泡沫剂和氮气，在地层孔道中产生泡沫，高强度的泡沫膜封堵高渗透层或大孔道，有效地抑制蒸汽进入高渗层、高渗段、高渗带并转向低渗层、低渗段、低渗带等未驱替带，增加驱替体积，提高蒸汽波及面积，改善油藏开发效果。

When air padding is allowed and appropriate, it is imperative that clean, oil-free, cooled, dry compressed air be introduced into the vapor space through its vapor valve to transfer the liquid.

压缩空气通过蒸气阀门进入蒸气空间，来转移液体。

The results show that the parameters of steam over water vapor supplied by the heating device is stable,besides,during taking steam over water vapor as coolant and lubricant,the tool wear was reduced about 50 and 40 percent respectively by com.

研制了以过热水蒸汽作为冷却润滑剂的绿色切削技术所需供汽系统中的二次加热装置，并用该装置进行了不同切削速度下改变冷却润滑剂切削45钢时的刀具磨损对比试验。

The test data indicate when the vapor mixtures with 82% ammonia at 120℃ passing through a molecular sieve module, the concentration of ammonia can be increased to 98%.Once the zeolite bed is saturated, the absorbed vapor is desorbed by microwave heating of the bed.

从目前的实验结果得到，在温度为120℃、压力为9 atm的条件下，通过分子筛后的氨气浓度从82%提高至98%左右，显示分子筛对於分离氨水混合蒸气有良好的效果。

In the module, liquid forms a falling film at the tube outside and contacts with the shell side vapor phase, besides, heating or cooling fluid flows inside the membrane tube for heat exchange with the tube outside liquid or vapor phases.

此设计使用壳管式多膜管装置，液相以落膜方式於膜管外与气相进行热质传，热交换流体於膜管内与管外之气相或液相进行热传。

The ethylene producing process includes: distilling 5-45 % concentration ethanol solution to obtain mixed ethanol-water vapor, heating the mixed ethanol-water vapor to 150-350 deg.c, catalytic reaction in a gas-solid reactor to obtain coarse ethanol product, cooling, gas-liquid separating to eliminate components with boiling point higher than 70 deg.c and obtain ethylene gas, and washing, drying and refining to obtain ethylene product.

其特征是将乙醇蒸馏和化学催化制乙烯工艺过程耦合，浓度为5～45％乙醇经蒸馏系统得到乙醇-水混合蒸气，该乙醇-水混合蒸气继续加热到150～350℃后进入气-固催化反应器中经催化剂作用得到产物为粗乙烯，粗乙烯冷却后，使用气液分离装置去除其中沸点大于70℃组分得到乙烯气体，乙烯气体依次通过洗涤、干燥和精制得到乙烯产品。
