By use of Fourier analysis techniques,we obtain some new properties of thealmost-periodic functions and extend the two-scale convergence method in the homogenization theory to the case of almost-periodic oscillation, this answers an open problem proposedby G.
利用Ｆｏｕｒｉｅｒ分析的某些技巧，得到殆周期国数的一些新性质，在此基础上将均匀化理论中的双尺度收敛方法推广到殆周期振荡的情形。
