unloading joint

The relationship among removal loading,coverage rate and inflow loading was studied.

研究了去除负荷与覆盖率及进水负荷之间关系,结果表明以30%覆盖率为分界点,去除负荷与覆盖率之间的关系有明显的变化;去除负荷与进水负荷之间满足二次函数关系。

The algorithm is based on knot removal, knot insertion, and weight modification of the NURBS.

针对平面三次 NU RBS曲线的光顺问题 ,基于节点插入、节点消去和重新确定权因子等技术 ,给出了平面三次 NURBS曲线的一种光顺算法 。

Methods Based on knot removal, knot insertion, and weight modification, the knots which are wanted to fair are selected automaticly, the control points and weights are modified locally.

方法　基于节点消去、插入和重新确定权因子等基本算法,根据给定的光顺准则,自动选择需要光顺的节点,局部修改控制顶点和权因子。
