diffusion n. 1.散布,發(fā)散。 2.傳播,普及。 3.冗長(zhǎng)。 4.【化學(xué)】滲濾。 5.【物理學(xué)】擴(kuò)散,漫射。 the diffusion of knowledge 知識(shí)的傳播。 diffusion of speech 演說的冗長(zhǎng)。 diffusion of light 光線的漫射。
For pc, the pulse diffusion layer only depends on the diffusion coefficient of cations and the pulse length, is not related to the concentration of the mass 單脈沖擴(kuò)散層的厚度僅取決于陽(yáng)離子擴(kuò)散系數(shù)和脈沖導(dǎo)通時(shí)間,與溶液本體濃度無(wú)關(guān)。
Based on the dc diffusion model, we build a duplex diffusion layer model which is composed of inner pulse diffusion layer and outer stable diffusion layer . in inner pulse diffusion layer, the concentration of ions fluctuates with frequency of pulse current; in outer stable diffusion layer, the transport speed of ions is almost stable all the time, the main purpose is to transport the ions from the mass to the pulse diffusion layer 在直流電沉積的擴(kuò)散理論基礎(chǔ)上,建立了脈沖電沉積的雙擴(kuò)散層模型,靠近電極為脈沖擴(kuò)散層,擴(kuò)散層內(nèi)金屬離子的濃度隨脈沖電流的頻率而波動(dòng);脈沖擴(kuò)散層外面包圍著一層穩(wěn)態(tài)擴(kuò)散層,其中離子的擴(kuò)散速度在整個(gè)過程中基本是穩(wěn)定的,作用是將主體溶液中的離子不斷向脈沖擴(kuò)散層中補(bǔ)充。
