查询词典 vapour-water

Dehydration process based on hollow fiber composite membrane is one of the crucial and effective methods to remove water vapor from industrial gases such as light hydrocarbon, compressed air, natural gas and so on. Dehydration of propylene with VP method was studied in the thesis. We prepared the PVA/PS、CS/PS and PVA-CS/PS hollow fiber composite membranes by spread method. The permeation behavior of water vapor among coagulable light hydrocarbons through composite membranes and asymmetric membrane was researched by vapor permeation method. Also a differential mathematical model was established which can describe dehydration of gas phase propylene.

本论文以采用蒸气渗透法脱除丙烯中微量水分为目标，制备了 PVA/PS、 CS/PS、PVA-CS/PS 中空纤维复合膜；研究了可凝性轻烃蒸气中的微量水分在复合膜、非对称膜中的渗透行为，建立了描述丙烯气相脱水的数学模型，并进行了模拟计算；深入探讨了水蒸气在交联 PVA 致密膜中的渗透机理。

The coaxal coherent chart of irrigation water puts allfactors into one chart:channel transport capacity, field water consumption strength ,benefit area and irrigation time.

灌溉用水合轴相关图把渠道供水能力，田间耗水强度，效益面积、灌水时间等因素融于一体，按照一定的关系以曲线或直线组绘成合轴相关图，通过该图即可初步设计渠道流量，选定灌溉面积，也可确定轮灌周期、轮灌面积等。

In this paper, the nanometer Co-Cu-B alloy powders had been prepared in solution of mixing cupric and cobaltous sulphate, by liquid reduction process, on the condition of pure water and the ethanol-water system, using KBH4 as a reducer, PVP as a dispersant.

本研究采用液相还原法，以KBH4作还原剂，PVP作分散剂，分别在二价钴、铜硫酸盐的纯水体系和乙醇-水体系下合成了纳米Co-Cu-B合金粉末。

25% arketai water dispering agent, 70% imiler water dispering agent, 4.5% high active cypermethrin emulsifiable solution and 20% haoniandong emulsifiable solution had strongest toxic effect on Coccinella septempunctata. 10% liuyangmycin and 1.1% matrine powder had weakest toxic effect, which should he avoided in production.

结论］25%阿克泰水分散剂、70%艾美乐水分散剂、4.5%高效氯氰菊酯乳油和20%好年冬乳油对七星瓢虫的毒杀作用最大，生产中应尽量避免使用。10%浏阳霉素和1.1%苦参碱粉剂的毒杀作用最小。

The results show that the development and dissipation of dynamic pore water pressure are coinstantaneous,which makes the plus and minus pore water pressure and seepage force both alternate with time.

动孔隙水压力随车速的增大而增大，而且由于水压力的存在路面弯沉和面层内的有效应力减小了，但水对沥青膜的乳化和置换作用加强了。

Water source heat pump Split unit central air-condition technology is from occident and using uniform colling water system.

Firstly the thesis made study on stress field、 displacement field、 yielding part in colluvial deposit and accretion before water accumulated and after water accumulated and made the conclusion that slope failure will take place easier in colluvial deposit than in accretion.The stability computation indicates that stability will decline either for colluvial deposit or accretion bank and decline more rapidly in colluvial deposit than accretion bank.

论文首先对崩坡积、冲洪积岸坡蓄水前后的应力场、位移场及塑性区的变化进行对比，结论为崩坡积体岸坡遇水比冲洪积体岸坡更容易发生破坏；通过对岸坡的稳定性计算，两种岸坡在蓄水后和水位骤降时的稳定性均明显降低，崩坡积体岸坡降低更为显著，且其天然稳定性较冲洪积岸坡为差。

This was not understood at the time, and therefore went unaddressed, until ascension became so distorted that we chose to stop ascending and wait for a time when all records would be revealed.
