用计算机随机模拟方法研究水田土壤圆锥指数

摘要: 本文将计算机机模拟法应用到估计水田土壤锥指数所需抽样容量的研究中，是一次新的偿试，结果表明，对服从威布尔分布的水田土壤圆锥指数，正态分布的抽样容量公式仍然适用。在具有统计性质的农业工程领域的问题中。计算机随机模拟方法作为实际试验的补充。能大减少费时费饯的试验次数，有着广泛的应用前景。

Abstract: The computer random simulation method was applied,as a new attempt,toinvestigate the sampling size required in estimating the paddy soil cone-index iNthis paper. The results indicated that the sampling size formula for NormalDistribution was applicable to paddy soil cone-index which follows Weibulldistribution. For problems with statistical characters,the computer random simulationmethod can help to reduce enormously the number of time and money-consuming ex-periments required,and be widely used in the area of agricultural engineering.
