Try to see the square perfectly; when you can do so draw a circle within the square; now place a point in the center of the circle; now draw the point toward you about 10 inches; now you have a cone on a square base; you will remember that your work was all in black; change it to white, to red, to yellow.

试著看清楚这个正方形；看清以后，在正方形中画一个圆；在圆心画一个点，然后把圆心的点向你自己的方向拉近10英吋。现在，你在一个正方形的底面上做成了一个圆锥；你应该能记住这个圆锥是黑色的；再把它变成红色、白色、黄色。

Transition curve has often been used to connect line and circle arc, in order that the line can gradually change to circle arc, or vice versa.

摘 要 缓和曲线一般用来连接轨道交通工程的直线段与圆曲线段，以实现二者之间的平稳过渡，这在有关工程测量著作中已有详细叙述。

The article presents the developing condition of PWM and SVPWM first.Then the theory of SVPWM is discussed in detail.The SVPWM is based on the thought of magnetic chain tracking.It makes the ideal magnetic chain circle of three-phased sysmmetry electric motor supplied by three-phased sysmmetry sine wave voltage for basis,uses the practical magnetic chain vector formed by the different switch modes of three-phased inverter to track the basic magnetic chain circle.During the course of tracking,the inverter changes the switch modes properly to form the PWM waves.Then the modulation wave of SVPWM is analyzed in detail.The modulation wave of SVPWM is implicit,but the analogous modulation wave in A-B-C axis needs to be calculated in order to expose the internal relation of SVPWM and SPWM.That is to show the implicit modulation wave of SVPWM. SVPWM actually is a transformed SPWM ruly sampled by the modulation wave which is injected by the zero prefaces based on space vectors.

本文首先对脉宽调制技术的发展现状进行了综述，在此基础上分析了电压空间矢量脉宽调制技术的发展现状；接着对空间电压矢量脉宽调制技术的基本原理进行了详细的分析和推导，SVPWM是基于磁链追踪的思想，它以三相对称正弦波电压供电下三相对称电动机定子理想磁链圆为基准，由三相逆变器不同开关模式下所形成的实际磁链矢量来追踪基准磁链圆的，在追踪的过程中，逆变器的开关模式作适当的切换，从而形成PWM波；然后详细分析了电压空间矢量脉宽调制技术的调制波，虽然SVPWM法的调制波是隐含的，但是为了揭示SVPWM法与SPWM法的内在联系，需要求出SVPWM在A-B-C坐标系上的等效调制波，也就是将SVPWM的隐含调制波显化；SVPWM实质是一种基于空间矢量在三相正弦波中注入了零序分量的调制波进行规则采样的一种变形SPWM。
