数字电路课程教学探究

Research on Digital Circuit Teaching Methods

数字电路是通信、电子、自动化等专业开设的一门重要的专业基础课,具有较强的技术性、工程性、实践性。对于数字电路的教学内容及方法必须紧跟时代的发展趋势,结合实际应用进行有效改进与更新,以达到培养学生思维能力和动手能力的目的。从教学现状出发,基于OBE教育理念,面向社会需求,以培养学生创新意识以及提高工程实践能力为导向,构建“1+2”教学模式,实现重基础、强能力、宽通道三维度均衡发展。

The rapid development of web crawlers has promoted the development of web page encryption technology,which makes data acquisition no longer easy.In this paper,we take an environmental quality website as an example,combine a variety of techniques to inspect and analyze its encryption in detail,compare its decryption costs such as time and effort,and finally choose the lowest cost and weakest defense to make a breakthrough,realizing data restoration and extraction,and cleverly solving the problem of encrypted web page data acquisition,so as to crawl data.
