给出了一维单面边界速度滑移问题的参变量变分原理，详细讨论了采用有限元法求解时的具体实施过程。原问题最后可化为求解一个参数二次规划问题。文末给出了一个Ｒｅｙｌｅｉｇｈ阶梯轴承有边界速度滑移时的算例。
The variational principle of parametric variable in the one-dimensional one-boundary boundary velocity slip problem is given, and the detailed implementation process when using finite element method is discussed in detail. The original problem can finally be solved as a parameter quadratic programming problem. An example of a Reyleigh stepped bearing with boundary velocity slip is given.
