卤化物与水玻璃复合物的抑尘性能

在恒温箱中测定了粉尘试样添加ＣａＣｌ２或ＭｇＣｌ２和水玻璃后的含水率与环境温度、湿度、有效抑尘时间等因素之间的关系．研究结果表明：（１）当环境温度低于３１℃，相对湿度高于６０％，粉尘试样中ＣａＣｌ２和水玻璃含量的质量分数分别达到２０％和１０％（ＭｇＣｌ２和水玻璃含量的质量分数为２３％和１１．５％）时，试样的含水率就能保持大于５％（质量分数）；（２）当环境温度低于４０℃，相对湿度高于５０％，粉尘试样中ＣａＣｌ２和水玻璃含量的质量分数分别达到２６％和１３％（ＭｇＣｌ２和水玻璃含量的质量分数为３０％和１５％）时，试样的含水率就能保持大于５％（质量分数）；（３）ＣａＣｌ２或ＭｇＣｌ２与水玻璃复合后，其粘尘功能进一步增强，而且其溶液的弱酸性得到进一步降低。     

The electrical conductivity of H_2O at 0.21-4.18 GPa and 20 -350℃

The electrical conductivity of H2O in solid and liquid phases has been measured at 0.21-4.18 GPa and 20-350℃. The results indicate: ( i ) different phases of H2O in solid have different relations between electrical conductivity and temperature and pressure. The conductivity changes continuously with temperature, but discontinuously with the pressure between 2.11 and 2.58 GPa, which corresponds to the transforming pressure between ice (Ⅵ) and ice ( Ⅶ ) ; ( ii ) the con-ductivity of H2O in liquid all increases with temperature and pressure, but there are discontinuities at pressures between 0.57 and 0.9 GPa, and between 2.11 and 2.58 GPa, which are also consistent with the polymorph of ice (ice ( Ⅴ), ice (Ⅵ) and ice ( Ⅶ ) ) . This reflects that H2O in liquid at different pressures has quite different properties of electron chemistry. It is prob-ably the important reason that causes the layers with high electrical conductivity and low velocity in the earth's crust and upper mantle.     

STUDY OF THE HEAT AND HUMIDITY TRANSFER PROCESSES BETWEEN AIR AND WATER IN THE AIR WASHER

The processes of heat and humidity transfer between air and water are what to be studied mainly in the paper, we put forward some main factors which influence the processes of heat and humidity transfer in the air washer. We come to the conclusion that we can change these main factors to achieve different heat and humidity transfer processes and decide processes of heat and humidity transfer of air and water with the initial temperature of spraying water in the air washer. All these results can make things convenient for the air conditioning management.
