第四部分对斯特拉文斯基作品中非功能化的和声进行做了具体的分析与比较研究，从单线条的旋律构成到调式化的和声进行、双调性多调性的结合、复调化和声进行等八个方面予以分类论述。

By adding an equivalent harmonic impedance in the branch circuit of power grid, this HAPF could force all the harmonic currents flow into passive power filters, which resulting in eliminating harmonic contamination more effective. And using the capacitive feature of PPF in the fundamental frequency, this HAPF could compensate fixed-capacity reactive power without increasing APF's burden. Moreover, in order to decrease APF's cost, the fundamental voltage will largely be endured by capacitor in view of the series resonance circuit tuned at the fundamental frequency, so the APF just bears little harmonic voltages.

其基本工作原理是：有源部分等效于在电网支路中串联了一个谐波阻抗，该谐波阻抗对基波电流不起作用，而对谐波电流产生很大阻碍作用，迫使谐波电流流入无源滤波器，从而达到滤除谐波的目的；同时新型注入式混合有源滤波器还充分利用了无源滤波器的无功补偿功能，在不增加有源部分容量的前提下，可以提供一定容量的无功功率；由于有源部分承受的电网基波电压不大，也没有基波电流流入，因此逆变器容量小，初期投资较小。

By study, majority of the research productions and theoretical papers are about how to control harmonic, and the harmonic analysis methods that were introduced are generally applied in large power system, these harmonic analysis methods usually use harmonic network's mathematic model (the conductance and susceptance matrix of the node). But because of the dissymmetry of some elements in power system, the mathematic model is very complex, so it is very complicated to calculate by these methods, we commonly combine with computer and use them to analyze large power system.

通过学习和了解，现有的研究成果和理论文章多数是介绍谐波的治理方法，而介绍谐波分析方法的论文一般是针对大型电力系统进行分析和研究的，这些谐波分析方法通常利用谐波网络的数学模型（谐波网络的节点导纳矩阵）进行分析，由于电力系统中的某些元件的不对称性，使得数学模型复杂，计算起来极为繁琐，因此，一般结合计算机用于分析大型电力系统。

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.
