In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.

从句子全长的对比看，祈使句的全长要比陈述句和疑问句短。虽然我们的实验语句属于口气比较委婉的祈使句，而这种祈使句的时长还是比陈述和疑问句大大缩短。三种句型的调核比较看，祈使句、陈述句和疑问句的调核音长在每个句型的5个音节中最长，占句子全长的大约百分之三十左右。从句末助词对比看，疑问句末助词"了"的音长跟祈使句"吧/了"和陈述句"了"的音长相比明显加长了。由此可见，在汉语中句末音节的时长与句型有密切相关，祈使句句末的语气助词的音长是属于短的。
