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.

2,9-二甲基-1,10-菲罗啉络合推动Ni~(2+)离子在水/硝基苯界面传递的研究

用半微积分伏安法研究了2,9—二甲基—1,10—菲罗啉(L)络合推动Ni(Ⅱ)离子在水/硝基苯界面的传递行为。在0.1mol/L NiCl_2(或NiSO_4)(W)—0.05mol/L TBATPB,L(NB)体系中,Ni(Ⅱ)与L生成NiClL~+(或NiL_2~(2+))络合离子,从而在W/NB界面发生离子传递。当C_(Ni~(2+))>>C_L,e_p与C_L成正比,线性范围为1×10~(-6)mol/L～5×10~(-4)mol/L,可作为L的定量分析。文中进行了理论探讨,测得了络合物的形成常数等。
