| 摘 要： | 鉴于现有文献中关于面状特征迹线转动角的计算公式(简称pp公式)与实验测量结果相差较大,笔者模拟薄晶体样品位向调整时的双倾操作过程,推导出计算面状特征迹线方向随样品倾转而变化的新公式。通过与实验测量值及pp公式计算结果相比较,证实本公式给出的计算值与实验结果相符,并再次反映出pp公式的不适用性。

| Abstract: | Simulating the orientation adjustment operation of thin foils by double tilting, a new equa-tion to estimate trace direction of planar features in TEM thin foils has been derived to replacethe existent one(1) which has been pointed out by the authors of the present paper that it isnot applicable. The experimental observations and measurements on Alloy In718 specimen showthat the calculated trace direction by the new equation are consistent with the experimental verywell. |
