本文研究了粘性大幅度变化对自下而上加热的流体层中对流的影响。假设无限普朗特数、自由表面边界条件和固定水平波长的二维运动，通过数值计算得到流场和温度场的解。温度依赖性和深度依赖性的粘度的影响进行了研究，也进行了计算，使用温度和深度依赖性的粘度模型适合地球的地幔。
The influence of large variations of viscosity on convection in a layer of fluid heated from below has been investigated. Solutions for the flow and temperature fields were obtained numerically assuming infinite Prandtl number, free-surface boundary conditions, and two-dimensional motion of fixed horizontal wavelength. The effects of a temperature-dependent and a depth-dependent viscosity were each studied; calculations were also carried out using a temperature- and depth-dependent viscosity model appropriate to the earth's mantle.
