We find the poles of determinant of the S-matrix are equivalent to the zeros of the Wronskian in the Laplace picture.

在散射的过程里，我们可以定义S-矩阵，而我们发现那些使S-矩阵的行列式发散的模，与在拉普拉斯转换下，Wronskian零点定义下的模是等价的。

An algebraic method is derived for calculating the number of zeros of Abelian integrals in this paper.

Logically, a society that wanted to feel enormously prosperous would both encourage its citizens to embezzle and try not to detect the crime. By this means,"wealth" would balloon though not an erg of productive work had been done. The satirical nonsense of the bezzle is dwarfed by the real-world nonsense of the zero-coupon bond. With zeros, one party to a contract can experience "income" without his opposite experiencing the pain of expenditure.

Galbraith 教授真知卓见地点出大家应该把这个数字统计一下，加进国民财富当中，从而我们可以知道心理上的国民财富为多少，理论上一个社会若想要觉得自己经济繁荣发展就应该多多鼓励人民去贪污舞弊，并试着不要去揭发它，透过这种方式，一个国家的财富可以大幅地增长，虽然实际上它什幺有生产力的事都没做。

Firstly,we particularly explained the algorithmic of themusic recognition.Then,we made a study of the music characteristic and the musicrecognition methods.As for the burrs of the music signal,we put forward a curveplastic method to eliminate the burrs.Considering the difficulties of detecting thepoint of the music speech,we made use of the multi-frequency energy curve to detectthe end-point of the music signal with the crossing zeros rate.As for thedisadvantages of the large operation and influence of the formant,we improved theAMDF theory with the linear prediction algorithmic to detect the error.In order toobtain the characteristic parameter of the music signal,wo calculate the MFCCparameter to obtain the template and the pending signal characteristic parameter.Inorder to improve the rate of the recognition,considering the disadvantages of theDTW algorithmic,we find a new method to improved the DTW algorithmic bybroadening the point of the music signal and made simulation experimentation;As forthe disadvantages of the contraposition grade to the pitch,cadent and sing name,wefind a method to dynaic adjust the results of the recognition to improve the accuracyof the grade.

详细阐述了嵌入式音乐识别算法的详细设计与实现，研究了音乐语言的特点和音乐识别的侧重点，并阐述了基于音乐信号特色的语音处理及识别方法；针对音乐信号中的毛刺干扰，提出了曲线整形的思想，消除了音乐信号中的毛刺；针对音乐信号端点检测困难的特点，利用多频段能量曲线分割结合过零率来实现端点准确检测；针对音高提取运算量大且容易受共振峰影响的特点，利用线性预测残差的方法对传统的AMDF算法进行了改进并提取出了音高，在实际实现时，优化了AMDF算法，减少了计算量；为了得到较好的特征参数，通过求取梅尔频标倒谱系数的方法，分别提取了模板信号特征参数和待测信号特征参数；为了提高识别率，针对传统DTW算法的缺陷，采用了放宽端点和声刺激法改进了传统的DTW算法的性能并进行了仿真试验，使音乐识别率得到明显提高；在音高、节奏评分时，针对对位评分的缺点，采取了动态调整的方法提高了评分的准确度。

研究发现此结构的非相邻谐振器之间亦具有频率相关的耦合特性。

Further more, we can suppose that every one of the two stars has the mass that is equal to one and half of the mass of the sun, that is, 2970 octillion (one with 27 zeros) kilogram.

我们还可以进一步假定，这两颗星的质量相同，都是太阳质量的1.5倍，即都是297万亿亿亿公斤。
