中文摘要：

以玉米芯为原料，乙二醇为液化剂，浓硫酸为催化剂，考察了不同的液化温度、液化时间、固液比以及催化量对玉米芯液化产物起沙风速的影响规律。采用扫描电子显微镜对玉米芯液化产物处理前后的固结层进行了测试，推断玉米芯液化产物的固沙机理。结果表明，玉米芯液化产物主要通过物理胶粘作用增加沙粒的抗风蚀性能。

英文摘要：

In this study, corncob was liquefied in ethylene glycol, with sulfuric acid as a catalyst. The liquefied corncob was used as a sand - fixing. The influences of the liquefaction temperature, time, corncob contents and catalyst contents on the threshold wind velocity. The sand crusts were characterized scanning electron microscopy （SEM）. The results revealed that the liquefaction corn cob can enhanced the sand cementation to resistance wind erosion.
