塑压接触面上之摩擦力,在一定时间作用于一定曲线族之切线方向,此曲线族称为“摩擦线”,其理论意义为:摩擦线本身为塑压表面流动之方向规律;其实际意义为:加工压力之科学计算有赖于摩擦线。在连续塑性变形过程中,接触面上质点之流动轨迹称为“长程滑线”,在塑压中一形状变为另一形状,长程滑线为始末形状间之表面变化规律。本支为一系列研究(例如[1]至[3])之续,目的及结果有三: (1)证明前文中摩擦线、等压线与压力布三个微分方程不受摩擦物理方程之约束; (2)提出椭圆板摩擦线族之另一解; (3)开拓出决定直观摩擦线的方法,定出塑泥及铅椭圆板之一系列摩擦线族,并对理论与实验结果作了比较讨论。金属摩擦线研究在进行中。北京钢铁学院的温金珂先生在本文前一作者指导下作过一长方板的摩擦线,她的结果将在长方板摩擦线系统化研究中一并发表。

用热分析法研究了锂-碳体系.制备熔体和记录冷却曲线是在氩气氛中进行的. 确定了体系在锂和所生成的碳化锂(Li_2C_2)之间这一部分的状态图.锂和碳化锂形成低共熔体,低共熔体的组成靠近纯锂(合碳少于1原子%),其熔点为165°. 用沸点法测定了纯锂以及含碳少于15克原子%的熔体在790-950°的蒸气压.根据蒸气压的等压线确定了在较高温度范围内的液相线. 碳化锂被水完全分解,放出当量体积的乙炔,并无自由态的碳及其他物质残留. 热分析及Debye-Scherrer法的结果指出:碳化锂有几种变体,转化温度约在410°,440°和560°.

Activity coefficients of MgCl_2-NaCl-H_2O system have been measured using isopeistic method at 25℃., For a series of ternary solutions at cons- tant water activity (between the range of 0. 7527--0. 9026) a linear variation of 1/m with x_1 (or x_2)was found where x_1 is the fraction of the salt NaCl, m_1=mx_1 and m defined as m=2m_1+3m_2 is the total concentration of ions in the solution. It is then possible to calculate the activity coefficients of both components by the simplified McKay-Perring equation. The α_(ij) and β_(ij) terms in Harned Rule are also evaluated at constant total ionic strength 4.5, 5.0, 5.5, and 6.0. The results indicate thai /3~ is very small, and the logarithm of MgCI2 is approximately linear with the ionic strength of NaC1 but as for NaCI a quadratic equation is required. The simple addltivity rule for vapor pressure lowering has been discussed and no sound evidence has been found in favor of the existance of special interactions between the ions in solution. When the eqilibrium concentrations of mx are plotted aga- inst m~, a series of straight isothermic-isobaric lines are obtained, this be- havior indicates that the system obeys zhdanovsky Rule.

在25℃,作者用等蒸气压法测定了MgCl_2—NaCl—H_2O三元混合体系达平衡后的浓度,结果表明当α_W在0.7527—0.9026的区间内,1/m~x_1(或x_2,m=2m_1+3m_2)具有綫性关系,因此可以将McKay-Perring公式简化后计算活度系数。在总离子强度恒定为4.5,5.0,5.5,6.0的情况下,求出了Hamed规则表达式中的系数α_(12),α_(21),β_(12)和β_(21),在实验的浓度范围内β_(21)的数值很小,可以略去不计。根据蒸气压加和规则的检验,以及等温等压线具有线性关系,表明在所讨论的浓度范围内离子之间没有特殊的相互作用,并且该体系服从Здановскии规则。
