波展开 meaning in Chinese

wave spread

On computational methods in photonic crystal finite difference time domain method ( fdtd ) and plane wave expansion method ( pwe ) are widely used in calculation the dispersion relation of the photonic crystals
光子晶体计算方法的研究用于计算光子晶体的计算方法中，有限时域差分方法( fdtd )和平面波展开方法被广泛使用，我对这两种方法都有所研究，也有所突破创新。
Being local in space and frequency , and some even compactly supported , wavelets are used to simplify the wave equations in slowly varying nonhomogeneous medium , and transfer the problem of solving two - dimension wave equations into a series of one - dimension problems , after words , the method in 1 can be applied to solve it . as a result , the complexity of the problem and the difficulty in solving it are largely reduced
利用小波变换在空间域和频率域上具有局部性的特点，通过小波展开，把二维非均匀问题转化为一系列一维非均匀问题，然后利用在(一)中得到的通用计算公式求解，大大降低了问题的复杂性和难度。
