摘要
对玉米秸秆的茎叶连接力、叶鞘的抗拉特性和茎秆、叶鞘的抗冲击特性进行了测试。结果表明 :这些力学特性是玉米秸秆的固有特性 ,具有统计规律性。茎叶连接力为 0 .7～ 16 N ,叶鞘抗拉力为 3～ 2 1N,叶鞘抗冲击能量为 0 .5～ 3.8J,茎秆抗冲击能量为 2 .3～ 4 2 .8J。并对影响这些特性的因素及其变化规律进行了分析。
In this paper, the joining force of stalk and leaves, the resistance of pulling force of vagina, and the resistant impact of stalk and vagina were tested as a preliminary research of cornstalk comprehensive utilization. The results show that the mechanical properties of cornstalk are its national properties following statistical laws. The joining force of stalk and leaves ranges from 0 7 to 16 N, the resistance of pulling force of vagina from 3 to 21 N, the resistant impact of stalk from 2 3 to 42 8 J, and the resistant impact of vagina from 0 5 to 3 8 J.
