1. Information Processing Definition of Information processing All operations exerted to the information itself for its better utilization Information processing is necessary because most of the information in its original form may not be good for use. Thus information processing is the basis of later operations Two categories of information processing: 1)Shallow Level of Information Processing 2)Deeper level of Information Processing

1. Model of Communication System Noise Source Sink T Channel T: Transformation Source, sink, and channel are given beforehand Transformation to match the source with the channel

Problems to be concerned with 1. How should we define the concept of Information 2. What are the typical features of Information compared with matter and energy 3. What are the relationship and difference between Shannon Information and comprehensive Information 4. How to reasonably classify Information 5. How to properly represent Information

一、例题精解 【例题2.1】在图2.2所示方框图中,N是一线性无源网络。当U1=1V,2=1A时, U3=0V:当U1=10V,2=0A时,U3=1V.试求当U1=0V,I2=10A时,U3=?

1.1 Information science Definition of information Science Information Science is a trans-disciplinary science with information as its object in study; the laws in information process as its content information methodology as its approach; and the strengthening human information functions particularly the intellectual ability, as its goal

板坯连铸结晶器浸入式水口吹氩使结晶器流场发生改变,引起液面波动,造成铸坯卷渣。为了的这一问题,采用大样电解方法结合扫描电镜技术,研究了板坯连铸结晶器浸入式水口不同吹氩量和吹氩分配方式对铸坯夹杂物的数量和类型的影响,提出了减少卷渣的合理结晶器吹氩量和吹氩分配方式,得出了卷渣占结晶器夹杂物的比例超过半数的结论。分析表明合理的吹氩参数对减少结晶器卷渣有着重要的意义
