actual measuring rod position的用法和样例：
- He measured the north side; it was five hundred cubits by the measuring rod.
- He measured the south side; it was five hundred cubits by the measuring rod.
- The process of high-precision measuring rod is described in this paper and seeks application of Carbon/epoxy composite in this new field.
- The analysis shows that the indicator owns more advantages over the coils-coding rod position indicator, so it can meet the demands of the rod position indicating in NHR.
