也可以选择在非氧化气体氛围中通过渗金属过程在同时使至少两个成形件反应接合时将它们转换成CMC复合材料。

Alternatively, these can be converted into a CMC composite material in a non-oxidizing gas atmosphere by a metal infiltration process with simultaneous reactive joining of at least two moulded parts.

结果表明：在气溶胶含量较高的气层内，气溶胶表面的非均相反应对气溶胶与微量气体的关系有重要影响。

The result suggested that stratospheric heterogeneous processes on aerosol surfaces is important for the relation between aerosols and trace gases in the aerosol-enriched layers.
