A new method of image de-noising based on a novel diffusion coefficient function is proposed, which is constructed by using some special characteristics of image features.
提出了一种基于新型扩散系数函数的图像去噪方法，这种扩散系数函数是利用图像特征的一些特殊性质构造出来的。
The simulated radial distribution function and diffusion coefficient also accord with experiment basically. Rather, the pair distribution function is consistent with the literature reported.
模拟获得的径向分布函数和扩散系数的值与实验基本吻合，分子间作用能分布也与文献报道的趋势一致。
Using the function between the porosity and the diffusion coefficient and frequency in the diffusion impedance, the finite diffusion model evaluated the porosity.
有限扩散模型则利用孔隙率与扩散系数和频率间的函数关系测定；
