| 摘 要： | 在DTE-T和S_A%-T转变曲线的中部其DTE和S_A%值分别具有较大的分散性,在此温度下时A131和A537钢焊接接头试件进行实验和统计分析表明无论是DTE还是S_A%均服从正态分布。对DTE进行蒙特卡洛模拟也证实了这一点。

| Abstract: | For the DTE and S_A% values there are large scatters at transition temperatures in the middle of DTE-T and S_A%-T curves. At those temperatures, a large number of welded specimens of A131 and A537 steels were tested and based upon the test data the statistical analysis was taken in this paper. From the results it is clear that either the DTE or the S_A% is confirming with normal distributions. For the DTE the conclusions are confirmed by means of the Monte-Carlo simulation, too. |
