玉米秸秆不同部位含水率特性和拉伸学特性研究

Study on the Moisture Content and Tensile Properties of Corn Straw

对玉米秸秆不同部位的含水率和拉压特性进行了研究,研究表明玉米秸秆不同部位的原始含水率自顶部至底部逐渐增大,且玉米秸秆在恒定的温度和相对湿度下达到失水平衡时,以及浸泡在恒温水浴中达到吸湿平衡时,其不同部位的含水率也表现出自顶部至底部逐渐增大。玉米秸秆不同部位含水率的这一不同,导致了其拉压力学特性也随玉米秸秆的部位不同而变化。

This paper studied the moisture content and tensile properties of corn straw.The initial moisture content of corn straw at different parts increased gradually from top to bottom.Besides,when the corn straw reach to the equilibrium moisture content at content temperature and relative humidity or soaking in water at content temperature,the moisture content of corn straw at different parts also increased gradually from top to bottom.This result in the different tensile properies of corn straw at different parts.
