1.分波法的一般公式 现在假设势场为中心势场V=(r),那么方程就变为 v2y+[k2-u(r)y=0.u(r)=v(r) 显然,这时f(0,)变成了f(0),(r,0,)变成了(r,0),而且2是守恒量,所以不妨假设

NewtonLagrange插值和插值虽然构造比较简单,但都存 在插值曲线在节点处有尖点,不光滑,插值多项式在节 点处不可导等缺点 设f(x)在节点a≤xox1,xn≤b处的函数值为yo,y1,yn 设P(x)为f(x)的在区间[a,b]上的具有一阶导数的插值函数

5.1定义和例子 1.令F是一个数域,在F里计算 (i)(2,0,-1)+(-1,-1,2)+(0,1,-1)

Note n, s enter the system at the same place F is fixed. We design(and perhaps B). We must stabilize F if it is given as unstable

Note that in the case of repeated roots of the denominator, a pole of multiple order contributes only a single residue. To evaluate F(s)ds by integrating around a closed contour enclosing the entire left half plane, note that if F()0 faster than-for large s, the integral along the curved part of the contour is zero

一、是否题 1.在一定温度和压力下的理想溶液的组分逸度与其摩尔分数成正比。 (对。即=fx1,f=f(T,P)=常数) 2.理想气体混合物就是一种理想溶液。 (对)
