The study of exceptional set has a history of half a century . in reference ( 2 ) , lento extended the famous picard theorem and presented the concept of exceptional set of entire functions and meromorphic functions . and the exceptional set in his result was an infinite sequence of complex numbers 例外集问题的研究,已有半个世纪的历史,在文献2中, lehto推广了著名的picard定理,并首次提出例外集的概念,在他的结论中,例外集为一无穷复数序列。
The two key parameters , back electromotive force ( emf ) and reactance of d q axial armature reaction are investigated , too . in the process of asynchronous starting , mathematics model of repmsm is established with 1 , 2 , 0 complex number coordinate system . combined with the model , electromagnetic torque is studied 论文还研究稀土永磁同步电动机的异步起动过程,建立了稀土永磁同步电动机起动时的数学模型,并对电磁转矩的性质进行了研究,论文还提出了起动时电磁转矩的计算方法,论文对稀土永磁同步电动机的牵入同步过程进行了原理性分析,论文也对电机参数对于电机起动性能影响进行了研究。
The statistic of wavelet transform coefficient algorithm can solve the periodic noise , high - energy noise and some non - gauss noise simply and effectively ; bi - spectrum can acquire more information from the original signal than power - spectrum , detect more information except from range and restrain the gauss noise . short - time speech signal can be considered as stationary and with periodic non - gauss signal , so we can make use of bi - spectrum to obtain the speech character and separate the speech and noise and detect morse telegraph signal ; complex number spectrum variance algorithm is put forward based on the deeply observing speech data , it is a new algorithm , experiment show that it is simple , effective 统计算法在解决周期信号、高能噪声和高斯信号方面有独特之处,能简单有效提取以上噪声的特征;双谱能够提供比功率谱更多的有用信息,有效地检测信号幅度之外的其它信息,并能有效抑制高斯噪声,短时语音信号一般认为是平稳且有一定的周期性的非高斯信号,因而可以利用双谱来提取语音信号特性并实现信噪分离;复数谱方差算法是在对语音信号进行深入观察和分析的基础上而提出来的一种全新的语音特征提取方法,此方法简单而有效的提取了语音、噪声的特征以及检测莫尔斯信号,基于实验表明,该算法取得了很好的效果。
( 3 ) negative electricity , radius , complex numbers , electrical values of ions , maturity of weathering profiles , distribution of elements in parent rocks , medium conditions , absorption of clay minerals and organic matters are important factors controlling geochemical behavior of elements during black shales weathering ( 3 )电负性、离子半径、配位数、电价、剖面发育程度、元素在母岩中的分布、介质条件、粘土矿物和有机质吸附作用等是影响黑色页岩风化过程中元素行为的重要因素。
This paper is devoted to seeking formulas and rules of representation for generating new fractal graphics . the main works are as followed : ( l ) construct new formulas for new fractal aspects after revisited methods for the visualisation of mandelbrot and julia sets based on ifs , we described the other new formulas originating from z z2 + c . including norton and polynomials iterated function , which have integer index instead quadratic index , we also constructed formulas with complex number index . 3 - d dynamical system is discussed then . besides the most widely used sequential visualisation methods , we designed two methods to change the original vectors and get new graphics with special effects 在对公式指数的推广中,包括指数为整数的牛顿迭代法和多项式迭代法,还包括指数为复数的迭代公式;在离散动力系统的吸引子生成算法讨论中,将复数z向高维空间推广,重点论述了生成了三维离散动力系统吸引子的收敛条件,实现了此吸引子对应的三维空间向量在平面上的投影图的条件;还讨论了迭代前对初值点进行两种不同变换对得到的分形图形的影响,以及这两种变换组合图形的生成。
