Why Statistical Mechanics? Understand predict the physical properties of macroscopic systems from the properties of their constituents Deterministic approach ma F need of 6n coordinates at t: r: and v but typically n= moles (1023)! Ensemble?rather than microscopic detail and its surroundings microcanonical, canonical, grand canonical

一、求下列电路中的未知电压向量或电流向量 R=10

Player i is rational\;R=nieN Ri. Also, Bi(E) is the event \Player i is certain that E is true\ and B(E)=neN Bi(E). This is as in Lecture 7. Let me introduce the following notation for iterated mutual certainty: B()(E)=E B()(E)=B(B-I)(E)). Then the definition of Bk in Lecture 7 can be rewritten as Bk

状态空间模型的一种特殊情况是零、极点数目相同。例如,已知 回顾我们首先将G(s)分解成两部分 第一个传递函数表征输入r与中间输出量x之间的关系 在时域内,这即是微分方程
