摘要 利用蠕变技术作为位错运动的宏观反映，研究了表面活性介质对萘单晶流量的影响。蠕变测试的结果可以通过指数依赖性 e=eo exp(-(Uo, - γP)/KT] 很好地描述。根据该方程，计算了两个基础滑行系统和 3 个新发现的非基础系统的活化能 Uo 和活化体积 γ。滑行系统的类型、其方向和表面活性介质的存在显着影响 γ。表面活性介质显着增加 γ，有时增加两倍。
Abstract The effect of surface active media on the flowrate of naphtalene single crystals was studied with the help of creep technique as a macroscopic reflection of dislocations movement. The results of creep tests are well described by an exponential dependence e=eo exp(-(Uo, - γP)/KT]. According to this equation the activation energies Uo and activation volumes γ were calculated for two basal glide systems and for 3 newly discovered non-basal systems. The type of glide system, its orientation and the presence of surface active media markedly affect γ. Surface active media considerably increase γ, sometimes twofold.
