摘　　要：本文采用WDW-5微机控制电子式万能试验机对不同含水率的粉碎玉米秸秆进行常温压缩成型试验，得到了不同含水率玉米秸秆压缩成型曲线，并对实验数据及结果进行了分析；同时实验结果表明，含水率越低，最大压强越大，比能耗也越大，为玉米秸秆冷态成型技术的进一步研究提供了基础参数。The experiments on cold state compaction of chopped corn stalks with different percentage of moisture were conducted by WDW - 5 electron universal testing machine. The curves of compression moulding were obtained; the experimental datas and results were analysed, and the results show that the smaller the percentage of moisture, the bigger the intensity of pressure and consumed energy correspondingly. All of these are the basis parameters for further research on cold state compaction of corn stalks.
