The characteristic equation of calculating the thaw bulb was drawn by mathematical simplification, and a satisfied solution was obtained by difference method. 通過(guò)一定的數學(xué)處理得到了計算融化圈的特征線(xiàn)方程，并采用差分法進(jìn)行求解特征線(xiàn)方程，獲得了滿(mǎn)意的結果。
It is then subject to such mathematical indignities as wavelet decomposition, multi-resolution Fourier analysis, polyphase filtering and discrete cosine transformation. 接下來(lái)它還要經(jīng)過(guò)一些數學(xué)處理程序，比如小波分解，多重分辨率傅立葉分析，多相過(guò)濾，離散余弦變換等。
