| 摘 要： | 介绍了木片取样的系统抽样方案,经验抽样方案和概率抽样方案,通过分析系统取样方案中含水率、规格片、朽木和树皮等检验项目的历史统计,提出含水率,规格片和树皮都服从近似正态分布的规律,并在此基础上预设了含水率的允差。

| Abstract: | The system sampling plan,engineering sampling plan and probability sampling plan were introduced for woodchips sampling.Through studying of the basis of history statistic data of moisture,size,bark and rot from system sampling plan,the laws was found that moisture,sizes,and bark were obeyed approximately normal,and basing on the distribution,the permitted deviation of moisture was set. |
