Therefore, the improved FCM clustering results can reduce the sampling errors and retain the main attributesof cloud classification samples.
改进后的聚类结果既消除了采样误差，又保持了云类样本的基本特征属性。

On the foundation ofsampling scheme by attributes, the suggestion has been made according to the characteristics of civil engineering structures based on the corresponding national standards.
在介绍计数型抽样检验原理的基础上，从建筑物鉴定检测的特点出发提出了采用相应抽样检验国家标准的建议。
