摘　　要：农用运输车的随机载荷可采用其均值、幅值二维随机变量描述，只要载荷均值和对数幅值的均值与标准差确定，就完全决定了载荷的统计特性。该文还例举了载荷谱的某些应用。The random load of farm vehicles can be described by its mean value, amplitude value and twodimensional random variables. So long as the average value of the load ,average logarithmic extents value and standard deviation (rootmeansquare deviation) are defined, the statistical characteristics of the load can be determined completely. Some applications of the load spectrum were introduced.
