千(百)分表不能单独使用,一般都装在表架上进行测量。如表架质量低劣,紧固不良或表架构件刚性不足将带来很大的测量误差。本文试图通过理论计算及实验方法来探讨这一误差并指出在实际测量工作中控制这一误差的途径。以期通过这一讨论,对表架刚性不足而带来的测量误差引起足够的重视。 One thousand (one hundred) sub-tables can not be used alone, are generally installed in the table rack for measurement. Such as the poor quality of the table frame, poor fastening or table frame member stiffness will bring great measurement error. This paper attempts to explore this error theoretically and experimentally and point out the way to control this error in the actual measurement. In order to pass this discussion, enough attention has been paid to the measurement error brought by the rigidity of the watch shelf.
