1.1 System Fundamentals Definitions System: Definitions System- integrity of elements that form a certain structure internally and perform certain functions externally. L von Bertalanffy: System --set of interrelated elements

主要内容小结: 1、C、L元件的VCR; 2、(t)+r2(t=rt 3、三要素法 r(t)=r(∞)+r)-r(∞)e 4、阶跃信号ε(t)与阶跃响应S(t)

Introduction By and large, I will follow OR, Chapters 1l and 12, so I will keep these notes to a minimum. J Games with observed actions and payoff uncertainty Not all dynamic models of strategic interaction fit within the category of games with observed actions we have developed in the previous lectures. In particular, no allowance was made for payoff uncertainty

1解:△S=KhW=Kn (N-n)l n! F=△E-T△S=△E- KTLn N-ln(N-n)-lnn!] 根据 Stirling公式:当N很大时,hN=NhN-N,将上式整理得 △F=△E- KTINIn N-(N-n)h(N-n)-nhn] 平衡时,自由能具有最小值,由于热缺陷n引起的自由焓的变化()xp=0

一、核外电子的运动状态包括 二、、电子运动L电子运动

步骤: （1)对激励源进行付氏分解,取几项看精度 （2)分别求出恒定分量(直流)、基波、谐波 作用下的响应。 直流作用时:0开路、L短路 基波、谐波作用时:采用相量法 （3)用叠加定理求响应。瞬时叠加

时域分析:f(t) (t)=()*(t) ↓分解 ↑ 基本信号(t)→l→h(t) 频域分析:f(t) yejot =(t)* H(jo)Fejot ↓分解 基本信号 sinot
