	<span style=\"font-size:14px;\">本文通过热重分析仪研究了杨木与红薯秆共混物的热解特性并进行了热解动力学分析。结果表明，杨木的热解主要发生在两个阶段，而红薯秆发生在四个阶段。随着红薯秆的添加量由0%增加到66.7%，混合物的起始热解温度向低温区移动，并逐渐与纯红薯秆的重合；热解活化能也随着红薯秆添加量的增加呈逐渐降低的趋势，这说明在主要热解阶段，杨木和红薯秆的一次热解过程是彼此独立的，没有明显的交互作用。<br />
In this paper, the pyrolysis characteristics of a mixture of poplar wood and sweet potato stalks were studied by using TGA, and the pyrolysis kinetics were analyzed. The results indicated that the pyrolysis process of poplar wood mainly occurred in two stages, and that of sweet potato stalks was in four stages. With an increase of sweet potato stalks ratios in the mixture from 0 to 66.7 wt.%, the starting pyrolysis temperature of the mixture moved to a lower temperature, and gradually over-lapped with that of pure sweet potato stalk; the pyrolysis activation energy also decreased with the increase of sweet potato stalk addition, which indicated that in the main pyrolysis stage, the prima-ry pyrolysis process of poplar and sweet potato stalk was independent of each other, and there was no obvious interaction.</span>
