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

Snow in 1959, in theory, the general education should be to make up for the limitation of the academic mind caused by the excessive subdivisions of disciplines. Currently, the curriculum of general education in Taiwan University is often used as the professional standard as to the concept in contents, or with science and natural sciences related fields, it may even be set as a leading role in balance seeking. It is; therefore, doubtable that while college education devotes in breaking the barriers of knowledge or academic disciplines, and attempts to establish enriched yet systematic general education, at the same time, helplessly returns to the breakthrough of academic condition described by C.P. Snow where "the Humanities" and "the Science" still confront anxiously. This would not only fail to achieve the consilience in knowledge but also lead to a possible fracture.

P Snow在1959所提出「种文化」的概上进发展的话，那麼通教育在上应该是弥补学科分工过细、导致学术心受到限制的现象；然而目前台湾的大学通教育，由於经常被当成与「专业」相标举的内容概，甚至是被定成与工或自然科学等相关域寻求平衡或对话的角色，因此免让人怀疑：当大学教育致於打破知或学科的藩篱，并且试图建丰富而有系统的通教育时，是否无且吊诡地重新走回史当时所描述并尝试突破改变的学术况－「人文」与「科学」依然充满紧张与对，知仅难以达到融通、甚至陷入另一种断的可能？

This paper takes time as the main line to describe the history of development of the state-owned railway and the joint venture railway in the Inner Mongolia, and divides the development process into three stages and draws maps for each stage. It also takes the longest joint venture railway-JiTong railway as the mail part and describes its preparation, construction, operation and performance of corporational process and also explores the problems of the entire process.
