The electrochemical reaction is characteristic of a low current density controlled by the stageofreaction, or of a high current density controlled by the mixed process.
电化学反应的特点是低电流密度为电化学反应步骤所控制，而高电流密度为混合过程所控制。

The results showed that during the initial stageofreaction, conversion rate was larger and the content of "oil" (include gases and water) in the product increased quick-ly.
结果表明，在反应初期，煤转化速度较快，氢初压和反应温度的提高对加快煤转化速度是有利的。

Since the combustion mechanism of coal varies during the different stageofreaction, the dynamic parameters obtained by thermoanalytical methods are mean values of the whole combustion section.
