The results showed that a significant positive association was observed at the sampling levels of 50 m^2, 100 m^2, and 250 m^2 quadrates, and a sampling size of 100 m^2 was more suitable than that of 50 and 250 m^2 for the inter-specific association analysis.

结果表明：20个乔木种群在抽样面积分别为50、100和250平方公尺3种取样水平上均表现为显著的正关联，但取样面积为100平方公尺，比50平方公尺和250平方公尺更为合适。

Taking particulate material as an example, the effect of micro-homogeneity of the material on the sampling error was investigated. The variation of the analyte contents with the grain sizes, and the possibility of stratifying the population by the grain sizes were studied.

Relying on both dynamic and static analysis methods,both microstructure and macrostructure analysis methods,both on-line and off-line analysis methods,as well as both along-line sampling and die sampling techniques,the author of this thesis studied and developed an on-line microscopic system,the on-line rheometers and the on-line samplers which are used in single screw extruding process for the first time. Based on the analyses of a plenty of experimental results, the thesis mainly discussed following several questions: solid-bed break-up phenomenon on macroscopic scale,melting and deforming mechanism of a solid particle on small particle scale,and polymer morphology on microscopic scale.
