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.

This thesis inductively points out where the logicians did not satisfied with the theory of type mainly lies in two points, the axiom of reducibility first and the vicious-circle principle second. This thesis has discussed Ramsay's improvements as well as the criticism from Godel. Then, it observes that they two had a common view, viz. rejecting the vicious-circle principle from the points of Realism. Against Russell's insisting on this principle, such a rejecting seems so distinguished, which, this thesis argued, was the deep difference between Realism and Nominalism shedding on the reality of classes.

文中主要探讨了莱姆塞对类型论所做的改进以及哥德尔对类型论的批评，指出这二者的共同点是从实在论的立场来拒斥恶性循环原则，他们对恶性循环原则的拒斥同罗素对它的坚持形成了鲜明的对比，本文认为，这种对比所反映出来的差别实际上就是在类的实在性问题上实在论和唯名论的差别。
