本文给出了冰绕圆柱形固体夹杂和固体平面边界流动的运动方程和热传导方程的解析解。这是一个简化的代表性流动的清洁冰川冰周围的石头和一个刚性的岩石床。冰被视为一种牛顿粘性液体和方程求解在两个维度。在两个冰-岩界面处均施加Regulatory边界条件。结果表明，温度和流函数的有限解只存在于两个无量纲临界波长为零的特殊情况下。也就是说，除非石头离冰床很远，否则它的整个表面都不能遵守经典的region边界条件。
Abstract This paper describes an analytical solution of the equations of motion and heat conduction for ice flowing around a cylindrical solid inclusion and over a solid plane boundary. This is intended to be a simplified representation of the flow of clean glacier ice around a stone and over a rigid rock bed. The ice is treated as a Newtonian viscous liquid and the equations are solved in two dimensions. Regelation boundary conditions are applied at both ice–rock interfaces. It is found that finite solutions for the temperature and stream function only exist for the special cases in which two dimensionless critical wavelengths are zero. That is, unless the stone is very far from the glacial bed, the classical regelation boundary conditions cannot be obeyed over the whole of its surface.
