Abstraction :This paper analyzes the principle of Butterworth digital filter,discuss bilinear transformation method of filter design;record a piece of voice by Microsoft voice recorders, carry on its a time-domain analysis, spectral analysis;then design a specified Butterworth band-stop filter based on the theory of bilinear transform,analyze the filter by the tool named Fvtool;and filter the voice signal acquired by voice recorder.finally compare its characteristics of frequency domain and time domain,study the applications of Butterworth filter in digital signal processing ,in particular in signal denoising.

本文分析了巴特沃思数字滤波器的原理，探讨了双线性变换法设计滤波器的方法；用微软录音机采集一段语音，对其进行了时域分析，频谱分析；然后使用双线性变换法设计了一个的巴特沃思带阻滤波器，并且使用fvtool对设计的滤波器进行分析；然后利用该滤波器对采集的语音信号进行滤波。最后对比滤波前后的语音信号的时域和频域特性，研究了巴特沃思滤波器在信号处理尤其是信号滤波去噪方面的特性和应用。

Secondly, the steady-state productivity model for horizontal well in gas reservoir is established. On the basis of solving the model, this thesis elicits the binomial deliverability equation by which absolute open flow potential and inflow performance relationship can be got and we can forecast the production performance of horizontal well in gas reservoir. In the end, on the basis of the theoretical analysis, this thesis explores homologous nodal analysis program.

Luxemburg"s thoughts and actions are faced with too many dilemmas. Some western scholars hold that her views are between Bolshevism and Socialist Democratism, namely,"the Third Line. In a final analysis, it results from the interactions of her false judgment and analysis of her then times and environment as well as her firmness in beliefs.

Second, in the viewpoint of crypto analysis, the practical requirement for the cryptographic function is to construct the function that can resist all the known crypto analysis and attacks. In advanced, the main cryptographic properties are compared, and the relation among these cryptographic properties is analyzed, including the trade-off ones. Get the conclusion that the construction of cryptographic Boolean function is to find out the proper Boolean function in the whole vector space under the restriction of several cryptographic properties required for the security system.
