独立测试结果间的一致程度称为重复性。这个是正确的吗

经过多次测量所得到的值的一致性是不可能的,只是其中的误差很小,或者你的测量标准物质根本无法检测出来.对于这个问题需要精度等级更高的测量物质去检测,对每次的测量误差进行记录,然后再去＝取其中的均方差.这种测量一般用于精度等级要求高仪器,称为重复性误差测量

哪些英语短句/聊天套路适合尬聊，游客能重复给任何外国人听？

这是在问搭讪的套路么？
最佳答案是：对不起，我可能迷路了，能告诉我卫生间在哪里么？Excuse me, I think I’m kinda lost in here. Could you tell me where is the restroom?

接下来就可以开始尬聊：

如果别人接招了，可以继续交流，OK，哪就可以用以下句式。
