1 Introduction Background for New methodology Modern natural science methodology is mainly based on matter and energy Even though matter and energy are still necessitate factors in information system, yet the characteristic feature of information systems, particularly the complex ones, is neither matter nor energy but information Without information, the complex information systems, like brain and intelligent life. cannot be understood

1 Fundamentals of Control Theory N. Wiener: Control theory in engineering, whether it is Concerned with Man, animal or machine, can only be regarded as a part of the theory of information [(G) Controller

本部分是对GIB4706.32-1996家用和类似用途电器的安全热泵、空调器和除湿机的特殊要求》 的修订。 本部分等同采用IEC60335-2-40(1995)及其第一增补件(2000),因此,本部分应与GB4706.1 1998(等效采用IEC60335-1:1991及其第一增补件)配合使用,在文本的翻译和编写过程中,力求准确 并考虑历史的延续性

一般说来,质点运动时其加速度常随时间而 改变,但在有些情况下,质点的加速度可以 视为是恒定的,即其值和方向都不随时间而 变。如质点在地球表面附近运动、电荷在均 匀电场中的运动等,均属这种情况。 已知质点的初始运动状态及质点的 加速度来求质点的曲线运动方程,是属于运 动学的第二类问题~即已知运动状态求运动 方程的问题

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

一、[交流电与简谐交流电的概念] Concept of AC and harmonic AC 交流发电机产生的感应电动势(inductive efm)和感应电流( inductive current)是随时间作周期性变化的,称为交流 电;并且符合余弦函数的振动规律,属于简谐振动( harmonic vibration),因而又称为简谐交流电

3-1 Measures of Random Syntactic Information Shannon Theory of Information Key point: 1. Information is something that can be used to remove uncertainty. 2. The amount of information can then be measured by the amount of uncertainty it removed. 3. In the cases of communications, only waveform is concerned while meaning and value are ignored. 4. Uncertainty and thus information are statistic in nature and statistical mathematics is enough

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
