摘要
介绍了简单随机抽样和分层随机抽样方法及其在检测中的应用方法和效果。通过工程实例表明,该方法具有精度明确、抽样样本量显著减少等优点,建议在既有房屋混凝土强度检测中应用该方法。
The simple random sampling plan and stratified random sampling plan has been introduced and the application means and effects of which also has been presented, it has some characteristics such as material precision and obvious reduce of sample size, and rational advice has been presented.
