stable diffusion

By carbon ion implantation , painting Ag slurry and electric plating Ni into / on the surface of nanocrystalline copper , some stable diffusion sources are obtained , in which the atoms are interstitial or substitutional .

然后进行表面离子注入碳，表面涂覆银浆和电镀镍等处理，在纳米晶层内部或表面得到一定浓度的间隙或置换溶质原子，热处理后考察它们的扩散行为。

The results showed that the diffusion process of Na + in the hydrogel was stable diffusion , and the penetration coefficient increased remarkably when the temperature increased , while the increase in penetration coefficient dropped when the temperature was over 60 ℃ .

结果表明，Na+在水凝胶膜中的扩散过程为稳态扩散，其渗透系数随温度升高而显著增大，但温度超过60℃，Na+渗透系数的增大幅度显著下降；

Asymptotically Stable Solutions of Periodic Diffusion Systems

周期扩散组的渐近稳定解

The three models of virulent gas leak and diffusion are established , respectively is : continual stable state leak and diffusion model , limited period stable state leak and diffusion model , transient state leak and diffusion model .

建立开发了三种有毒有害气体泄漏与扩散模型，分别为：连续稳态泄漏与扩散模型、有限期间稳态泄漏与扩散模型、瞬态泄漏与扩散过程模型。
