单词	contour integration
释义	contour integration A contour integral is a path integral ∫C f(z) dz of a function f in the complex plane along an oriented, usually closed curve C. Such integrals can be evaluated using Cauchy's Residue Theorem; using appropriately chosen contours and integrands, and then taking real or imaginary parts, a vast range of integrals and series can be determined. For example, the substitution z = eiθ changes the integral into the path integral where C is the positively oriented unit circle centred at 0. The new integrand has a double pole inside C, the residue of which can be determined and so the integral evaluated.
