NURBS curve equation has three kinds of the equivalence form, i. e. rational fraction, rational base function and homogeneous coordinate.
NURBS曲线方程具有三种等价形式：有理分式表示、有理基函数表示和齐次坐标表示。
The equivalence procedure is based on the base power flow; the whole system can be divided into three parts:the inner nodes, the border nodes and the outer nodes.
该等值过程需要依托于基态潮流，根据地域性，将全网分为外部节点、边界节点和内部节点三部分。
But the principles of stress equivalence could accurately reflect the influence on the cement concrete pavement stress by the modulus and thickness of semi-rigid type base.
而以板底拉应力等效为指标的基层顶面当量回弹模量值能较为真实地反映基层刚度和厚度变化对板底拉应力的影响。
