第一章 1.1证明:1°由数学期望的定义,且X是非负随机变量,有:E(N)=nonp(n=n=1P(nn),令m=n-1,有:E(N)=np(nn)=mpnm+1)=2m=p(n>m)=n-p(n>n)2°先证明一般情况。由数学期望的定义,且X是非负随机变量,有:E(Xn)=)= Jntn-I- dt dF)

Solubility limit for P at 1273 K is Co 2 1 x 10 cm\. Intrinsic carrier concentration is 10 cm\. Thus, before including higher order terms, Do=13x10-4 cm2/s. But with first order and second order correction terms

All the questions are from Plummer, Chapter 10, p.679-680, which was handed out in class 1)Question 10.3 2) Question 10.4 3)Question 10.5 4) Question 10.6

标量函数场的梯度公式:若某一标量场的函数关系已经确定,为=T(x,y,z), 那么如何确定标量场在域中任意点的梯度(假设该点坐标为P(x,y,z)) 在P(x,y,z)点附近任意点P(x,y,z2)的标量场为V(x,y,),则两点标量场值差 可由泰勒展开为:
