To do this, the monotone curve is firstly drawn, and then without finding the coordinate of the inflexion point, the NC machining path can be obtained by the method of automatic direction control.

首先对单调NC轨迹曲线进行绘制，进一步用不求极值点坐标而实现自动控制变向的方法，求出NC加工轨迹；

Has her death come as an inflexion point in India's history, which will force the government to enact tougher laws and people to begin seriously thinking about the neglect of women?

The rule of thumb is that a 10pc rise in crude cuts US growth by 0.2pc four quarters later, but the science is flabbily soft and nobody knows where the inflexion point lies.
