针对强度计算时采用不同面积进行了分析，结果表明公称面积和实测面积的差值在1％以内，采用公称面积计算强度，不影响合格率。同一个批次内，用公称面积计算代表了试样的平均性能结果，变化范围更小，减少了由于面积测量引入的差异。采用公称面积有利于加严负偏差控制。
針對彊度計算時採用不同麵積進行瞭分析，結果錶明公稱麵積和實測麵積的差值在1％以內，採用公稱麵積計算彊度，不影響閤格率。同一箇批次內，用公稱麵積計算代錶瞭試樣的平均性能結果，變化範圍更小，減少瞭由于麵積測量引入的差異。採用公稱麵積有利于加嚴負偏差控製。

According to the calculation of the strength are analyzed with the different area , the results show that the nominal area and the measured area difference within 1%, with nominal area calculation strength , does not affect the rate of quali-fied.The same batches, calculate the average performance results represent samples with nominal size , narrower, reduces due to the difference of area measurement is introduced .With nominal area is conducive to the strict negative deviation con-trol.
