Question

请英语高手来帮忙翻译一下,谢谢

1 。The average value for d2 taken from a number of meas- urements shall not be greater than the value specified for d2 plus the interference allowance. For seals having grooved outside surfaces, additional interference al- lowances are to be agreed upon
2. The tolerance on d2 (¡.e. d2max- d2min) is to be deter-
mined by taking three or more measurements equally spaced around the circumference.
这是din3760油封标准中的一段技术要求，感谢大师们帮忙了

Answer 1

1. 由多次测量得到的d2的平均值不得大于d2的规范值加干扰容限。对于外表面带有凹槽的密封条，需要定一个额外的干扰容限。
2. d2的公差（即d2的最大值-d2的最小值）可通过取得圆周上间隔相同处的三个或更多测量值来确定。
