摘要：

用三种生物质试样（棉花秸秆、玉米秸秆、小麦秸秆）进行压缩实验。实验目的为确定这几种生物质材料在压缩状态下压力与密度之间的关系，由关系曲线的结果导入公式ｒ=kpn；通过该密度公式，观察由于不同湿度或不同种类的生物质，导致的常数k值和n值的不同。

The compressed test of three biomass materials(cotton straw, corn straw and wheat straw) was made .The aim of the test is to confirm the relationship between the density and preasure of these materials , and the results were inducted into the formula ｒ=kpn. The effect of the different materials and moisture on constant k and n was investigated.
