温度场对自蔓延高温合成致密化的影响

在自蔓延高温合成（SHS）致密化工艺中，准确确定施压滞后时间是工艺控制的关键．施压滞后时间的上限值一般是根据SHS过程的坯块表面温度与时间关系曲线获得，难以真实地反映坯块内的温度变化．作者以传热学理论为基础，针对SHS－准热等静压过程，建立了燃烧产物内的温度分布方程，并以此解释了最终产物内密度分布存在差异和形状变化的原因．     

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.

用两亚点阵ＭＦＴ分析了Ｒ２Ｆｅ１７－ｘＭｘ合金的饱和磁化强度与温度的关系。得到了分子场系数ｎＲＲ、ｎＲＦ和ｎＦＦ，计算出了居里温度，给出了分子场ＨＲ（Ｔ）、ＨＦｅ（Ｔ）与温度的关系曲线。计算结果表明，在Ｒ２Ｆｅ１７中用Ａｌ、Ｇａ替代部分Ｆｅ离子后，分子场系数ｎＦＦ明显增大，除Ｐｒ２Ｆｅ１７的ＨＲ（Ｔ）外，分子场强度在很大温度范围内显著增加     

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.
