cubic curve meaning in Chinese
立方次曲线
三次曲线
三次线
Examples
- The planar quadratic system with an invariant cubic curve has at most one limit cycle
类方程的极限环存在性的注记 - The cubic curve is constructed from the first point to the fourth point by using the second and third points as control points
立方曲线以第二个点和第三个点为控制点，从第一个点到第四个点来构造。 - If there is a previous line or curve segment in the figure , a line is added to connect the endpoint of the previous segment to the starting point of the cubic curve
如果图形中已有一段直线段或曲线段，则添加一段直线连接已有线段的终结点和立方曲线的起始点。 - If there are previous lines or curves in the figure , a line is added to connect the endpoint of the previous segment to the starting point of the first cubic curve in the sequence
如果图形中已有直线或曲线，则将添加一段直线连接已有线段的终结点和序列中第一段立方曲线的起始点。 - In order to verify the feasibility of ann , adopting same training sample the author establishes quadratic curve model and index model of tourism foreign exchange income and cubic curve model and index model of total inbound tourist quantity
