In the sense-representation of external things, the quality of space in which we intuite them is the merely subjective side of my representation of them (by which what the things are in themselves as objects is left quite open), and it is on account of that reference that the object in being intuited in space is also thought merely as phenomenon.
在我们感知外物的表象时,我们在这个空间中(也就是我们得以直观外物的空间)所获得的感受是全然主观的(而物体的真相在此则维持一个非常开放的状态),也就是因为这样主观的指涉,被我们在空间中所直观的客体才会被认为只不过是一种「现象」。

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。

Chapter four is the empirical research part in this paper. It introduces the principal of appraisal index and the choosing of the indexes. Then it introduces the building of model and its disposal method in Spss. To get a clear view of principal components analysis the paper analyzes the differentiate and connection between PCA and factor analysis. In this basement, the paper introduces the disposal process and results of the model. The paper then improves the model with entropy right method to eliminate the portrait diversity of data. To validate the model's stability, the paper makes a significance test of the four results.
