Two merging methods of Bézier curves are generalized to tensor product Bé zier surfaces, we propose two methods to approximate two pieces of adjacent tensor product Bézier surfaces by a piece of tensor product Bézier surface. We offer the explicit formulas of the merged tensor product Bézier surfaces with all kinds of merging conditions.
同样,Bézier曲线的两种合并方法也被成功的推广到张量积Bézier曲面上,得到把两片相邻张量积Bézier曲面合并成一片张量积Bézier曲面的两种合并方法,并给出在各种合并条件下的合并曲面控制顶点的显示表示式。

The study has focused on: 1 The research background and the current state of the power measurement were analyzed systematically, and then wavelet-based power measurement algorithm was certified feasible for astable signals; 2 We developed a new method of RMS and power measurement based on Dmeyer wavelet. After that three other wavelet measurement approaches were compared with Dmeyer wavelet-based measurement approach. Then the impact on measurement errors of amplitude frequency property and energy leakage of wavelet filter banks were deeply researched, and some measures were proposed to reduce it; 3 We developed a new strategy of power measurement algorithm based on lifting wavelet, which had calculation advantage compared with the first wavelet, so that it was more suitable for the realization of hardware; 4 The running system of wavelet-based power measurement algorithm based on DSP was proposed, and then it was realized on ICETEK-VC5416-A EVM board; 5 Existing problems and the further research direction of wavelet-based power sub-band measurement algorithm was discussed.
本文对基于小波变换的功率测量算法展开深入的分析研究,主要内容有:1)系统地分析了功率分解测量的研究背景、国内外的研究现状,并从能量守恒的角度验证了小波功率分频带测量算法在非平稳信号条件下的可行性;2)首次提出了Dmeyer小波变换有效值与功率的测量方法,进而通过对该方法与3种已经提出的小波测量方法的对比分析,深入研究了小波滤波器组的幅频特性和能量泄漏特性对测量误差的影响,并针对电网谐波的特点提出了减小影响的相关措施;3)首次提出了二代小波功率测量算法,对比一代小波功率分频带测量算法,它大大减少了算法实现的运算量及内存的需求量,从而更适合于硬件的实时实现;4)提出了小波功率分频带测量算法的DSP实现方案,并在ICETEK-VC5416-A EVM板上进行了实现;5)探讨了小波功率分频带测量算法目前仍存在的问题,并提出了进一步的研究方向。
