U-Ti二元合金热力学性质

The relationship between U-Ti formation heats and mole fraction of Ti was obtained by Miedema’s model.△mixSE,△mixGE and activity coefficient of the system were calculated based on the free volume theory considering excess entropy and some basic relationships of thermodynamics.The results indicate that U-Ti solution has negative deviation to ideal solution,and the deviation should increase with the decrease of temperature.

绝缘粉末与金属管导的摩擦带电

绝缘粉末通过金属管导时,两者带上等值异号电荷。本文根据这一现象提出了获得静电高压的基本原理,实验装置和实验结果。实验结果表明,有机玻璃粉末连续通过长20厘米直径5厘米的金属管导时,4秒时间管导电压可上升到52.8KV。文末还提出了两种粉末静电高压发生器的设计方案.
