结构误差 meaning in English
structural error
Examples
- Only the main transmitted light from the glued layer or the first - order transmitted light also , is considered at most in the existing study outcome about light intensity transmission . on occasion , some experimental results about light transmission are given as a performance index . and nearly no one considers the contribution of the higher - order transmitted lights and the effects of the inaccuracy in glue technology on light distribution
人们对它的研究，往往只考虑棱镜胶合层的两切割斜面上的主透射光束，至多同时考虑次级透射光束对出射光强的影响，或直接将光束光强透射比的实验值的平均结果作为棱镜的一个性能指标给出，很少考虑棱镜胶合层间光束的多次反射对输出光强的影响以及结构误差和使用调整误差对棱镜光强分布的影响。 - The error compensation software for cam precision grinding has been developed , and results show that the cam grinding accuracy can be ensured and the productive can be improved . ( 1 ) by using the method of movement error analysis of mbs , the geometric error model of sk - 21 nc machine tool has been established , and the calculation equation for precision processing of nc machine tool has been derived , which lays a good foundation of programming the error compensation software
基于该磨床目前的状态和已有的研究成果,本课题展开了以下主要研究工作: ( 1 )以多体系统运动学理论为基础,建立精确的sk - 21数控凸轮磨床运动模型,全面考虑各项结构误差和运动误差对加工精度的影响,推导出精密加工约束条件方程,揭示机床实精密加工的实质。
