问:用M-2、东德悬丝磁力仪工作时,到底要读几次数?我主张读两次就可以。但听别人说,读四次取平均读数准一些,也有道理。因此虽然我反对读四次数,但仍照四次读数。请问到底应读几次数好?编者按:这个问题很有意义,我们的意见是:请大家讨论,不必要由少数人来回答。 Q: When using the M-2, East Germany suspended wire magnetometer to work, in the end to read a few times? I advocate reading twice. However, listening to others, it is also reasonable to read the average reading four times. Therefore, although I object to reading the fourth number, I still read the fourth reading. In the end should read a few times better? Editor’s Note: This question makes sense, our opinion is: Please discuss, do not need to be answered by a few people.
