solid-phase diffusion

A PFG NMR experiment for diffusion in solid samples in the presence of eddy currents

固态样品中扩散的核磁共振测量

The principle of the limit current type oxygen sensor are briefly described, based on this theory, the porous layers type oxygen sensor is made, which diffusion layer is composed of ZrO_2 solid electrolyte and the porous ceramics plate.

极限电流型氧传感器工作原理是基于稳定ZrO2固体电解质的氧泵作用，通过气体扩散控制供给阴极的氧而得到极限电流。

The solid diffusion coefficient of lithium ion within insertion-host lithium ion battery of materials LiCoO_2 was determined by capacity intermittent titration technique ( CITT) under different voltages.

采用容量间歇滴定技术在充放电仪上测定了不同电压条件下嵌入型锂离子电池正极材料LiCoO2中Li+的固相扩散系数。

Oxygen sensor of limiting current type with a porous layer on platinum film electrode to limit the diffusion rate of oxygen was fabricated using the solid electrolyte of nanocrystalline ( 20~ 30nm) YSZ based.

制作了以纳米（20～30nm）YSZ粉体为原料的电解质基片、Pt电极上带有多孔涂层的扩散控制极限电流型氧传感器。

Studies suggested that it has greater thermal diffusion coefficient because alumina high-temperature melt, temperature wave was relatively apt to pass to solid-liquid interface, so that caused the temperature of the interface to gurgitations;

研究表明由于氧化铝高温熔体具有较大的热扩散系数，温度波较容易传到固液界面引起界面温度起伏；
