研究了不同含硅量的硅系铸铁中氢的分布后得出：无论是化学成分分析，还是微区成分分析，随铸铁中含硅量的变化，氢的含量也发生相应的变化．这就是硅系铸铁在自然状态下，其含氢量的分布特点．文中对此做了初步的理论分析．
The distribution of hydrogen in silicon cast iron with different silicon contents was studied. The results showed that the hydrogen content also changed with the change of silicon content in cast iron, no matter in chemical composition or microstructure composition analysis. This is the silicon cast iron in the natural state, the distribution of hydrogen content. The article made a preliminary theoretical analysis.
