【判断题】区间 上连续函数 一定有原函数.
A.
正确
B.
错误
【简答题】双面水准尺 一般长三米正反两面都有尺寸标记,正面黑白相间,称为黑面尺或主尺,尺底为零点;反面红白相间称为红面尺或副尺,尺底为某一数值如 4.687 米或 4.787 米。所以同一视线高在尺两面的读数总差一个常数,这样就可以避免 ( ) 和纪录产生错误。
【简答题】常用的普通水准仪是双面直尺,尺长()m、黑面底部的起始数为(),红面底部的起始数分别为()及()。
【简答题】三、四等水准测量使用的双面尺的一面为黑色分划,另一面为红色分划,同一把尺的红黑面分划相差一个常数,其中A尺的红黑面分划常数为 ,B尺的红黑面分划常数为 。
