氢压力 meaning in English

hydrogen pressure

2 . the pressure - and time - dependent fiber photosensitivity was studied in this paper and the uv - induced index changes were measured . the results show : while hydrogen pressure was increased , the photosensitivity gradually increases ; while hydrogen - loading time prolongs , the change of photosensitivity is consistent with the evolution of hydrogen concentration
二、研究了不同载氢压力下和不同载氢时间下的掺锗石英光纤的紫外光敏性，结果表明：掺锗石英光纤的光敏性随着载氢压力的增大，光纤的光敏性逐渐提高；随着载氢时间的延长，光纤光敏性的变化规律符合载氢模型。
