氚在1mm的未涂覆Al2O3的区域对应的FeCrAl中的浓度高于间隙的氚浓度。这主要是由于无Al2O3涂层，间隙与FeCrAl直接接触，间隙的氚浓度被FeCrAl内表面吸附过程由Sievert' law方程控制。Al2O3中的氚浓度也低于FeCrAl中的氚浓度，由于氚的扩散由高浓度向低浓度扩散，这说明氚绕过了Al2O3，从未涂覆Al2O3的区域直接被FeCrAl内表面所吸附。

The concentration of tritium in the corresponding FeCrAl in the 1 mm uncoated Al2O3 region is higher than the tritium concentration of the gap. This is mainly due to the absence of Al2O3 coating, the gap is in direct contact with FeCrAl, and the tritium concentration of the gap is adsorbed by the inner surface of FeCrAlThe adsorption process is controlled by Sievert' law equation. The concentration of tritium in Al2O3 is also lower than that in FeCrAl, and since the diffusion of tritium diffuses from high concentrations to low concentrations, this indicates that tritium bypasses Al2O3 and is directly adsorbed by the inner surface of FeCrAl in areas that have never been coated with Al2O3.
