| 通过对圆分度测试时取点数的具体分析研究,说明了测试点数与误差的关系,即测点数太少会漏测粗大误差,从而不能正确地反映仪器的误差,达不到较好的工艺要求。 |
| 英文摘要: |
| In this paper, the relationship between the nmber of test-points and the error is presented by analyzing and researching in the effect of the number of test-points takcn duri g testing Cir-cle dividing. Taking fewer testpoints sometime induces the missing of large error. Therefo, the device's error can't be correctly rcflected and better technological repuiremcnt can' t be met. |
