The paper introduces that asymptoticapproximation is drawing near the structural verified point, and also its application in structural reliability design is illustrated with an example.
本文介绍了用渐进方法在结构验算点附近进行逼近，并举例说明了该方法在结构可靠性设计中的应用。

Our proof of the convergence is based on an asymptotic diffusion expansion and requires error estimates on a matched boundary layer approximation to the solution of the discrete-ordinate method.
其收敛性的证明是依据其渐近扩散展开式，在边界层上得到的误差估计逼近其离散纵标方法的解。

The stationary phase approximation is a basic principle of a special class of asymptotic fourier analysis, such as oscillatory integrals.
