along with the development of digital technology,digital filters are widely used in many fields,this paper introduces how to design a iir digital notch filters in matlab environment.the design of digital notch filters can be achieved through three steps:firstly,the design of analog lowpass filter; secondly,it is analog lowpass to analog band stop filter conversion;at last,using the bilinear transformation make the analog notch filters change into digital notch filters.the paper also introduces how to design the transfer function of the digital notch filters using all the zeros and farthest points at the same time,it also introduces the program of the digital notch filters under butterworth analog lowpass prototype.

摘 要：随着数字技术的发展，数字滤波器在许多领域得到广泛的应用。研究一种在matlab语言环境下设计iir数字陷波滤波器的方法，在数字陷波滤波器设计过程中，先进行模拟低通滤波器的设计，然后进行模拟低通/模拟带阻滤波器转换，最后采用双线性变化法将模拟陷波滤波器转化成数字陷波滤波器。提出一种用所有零点和极点来表达数字陷波器传递函数的方法，同时给出以巴特沃斯模拟低通为原型设计数字陷波滤波器的程序。关键词：无限冲激响应；巴特沃斯滤波器；数字陷波滤波器；matlab；双线性变换

Testing two Microsoft Office 2000 Excel files, performance table for swine on farm test and cow type classification score, the Linux open office in USB stick can open the breeding data files and transform the existed mathematic functions of the files. From this pilot study, results showed USB bootable flash disk not only can use in mass animal breeding data storage but also can use as an independent tool kit for animal breeding and selection practice.

以USB随身碟开机后，测试原来应用於现场的Microsoft Office 2000 Excel 种猪选拔指数运算表及乳牛评分表，则均可於Linux 版的Open Office-Calc下开启并自动转换原来编写的函数，初步结果显示USB随身碟除了可提供便捷的育种资料贮存外，亦有可能发展成独立的随身育种工具组。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
