| 摘要: |
| 用数理统计的方法在万能试验机和压力试验机上对干麦秆、浸湿麦秆和绿麦秆的压缩剪切力学特性进行了研究。得出了麦秆的力与变形、湿度、面积、外径的多元线性回归方程和在指定条件下的力与变形的关系，还测出了麦秆的强度模量值。 |

| Compression and Shear Properties of Wheat Stalk |
|
|
| Abstract: |
| On the basis of mathematic statistics analysis,the author studied compression and shear properties of dry stalk,soaking stalk and green stalk of wheat by universal testing machine and pressure tester,established the multiple linear regression equation of force between deformation,moisture content,section area and external diameter,gave the relation between force and deformation of wheat stalk under the given condition,also measured the strength modulus of wheat stalk and relation between force and deformation when it compressed. |
| Key words: wheat stalk,characteristic of compression,characteristic of shear, |
