| 摘要: |
| 我们对矮丰三号小麦茎秆的力学性质进行实测,取得各节间的强度极限、弹性模量、波松比以及不同含水率情况下的强度极限。本文分析、研究了这些表征力学性质的量值的变化范围和规律,并用图线显示其规律性,从而确定了这些量值和找出最弱节间的所在。 |

| Abstract: |
| We measured mechanical properties of stems of wheat cultivar--Aifeng No.3 in the field from which date about ultimate strength of individual internodes,modulus of elasticity,Poisson's ratio and ultimate strength in the case of different water content ratios in stems were obtained.This paper discussed the varying range and regularities of measured values of these characterization mechanical properties,whose regularities were showed by charts and diagrams,and hence,measured values were determined and the weakest internodes were found out. |
| Key words: stems of wheat,mechanical property,modulus of elasticity,ultimate strength,regularity |
