解释了水蒸气保护焊焊缝的氢质量分数不高，不出现气孔的原因。
The reason for not high hydrogen content and free porosity in welds with this process is explained.
实验表明，在贮氢电极中添加3 %质量分数的银添加剂，电极容量略为增加，且明显降低了模拟电池的析气量。
The results showed that the discharge capacity of the MH electrode increased slightly when 3% silver was added, but the amount of the gas evolution from the simulated cell was obviously reduced.
当氢含量大于0.2%(质量分数)时，由于此时氢元素的固溶强化起主导作用，因此随氢含量的增加，峰值应力随之增加。
When hydrogen content was bigger than 0.2%, the peak stress increased with the increase of hydrogen content, because hydrogen played a main role of strengthening.
