Though ultra precision lathe developed by HIT have higher manufacturing accuracy, it has no ability to compensate for errors. If on the foundation of old CNC system, a valid error compensation system were added, the manufacturing accuracy of the lathe would be improved largely, at the same time theory and methods used in this paper can be applied to other machine too1s, So the study in this paper have both the significant theoretical meanings and the practical value.

哈工大研制的超精密车床虽然具有相当高的加工精度，但是其数控系统本身不具有误差补偿功能，如果在原数控系统的基础上，增加误差补偿控制系统，该车床的加工精度将有大幅度提高，同时文中所用理论和方法也适用于其它机床，因此本文的研究具有重要的理论意义和应用价值。

The finite difference time-domain method is stable and easy to be used, but due to the fact that it approximates the space derivatives in Maxwells curlequations by central difference, FDTD usually requires more than 20 grids perwavelength to achieve acceptable accuracy. As a contrast, pseudospectraltime-domain method approximates the space derivatives by pseudospectralmethod, which guarantees the accuracy, theoretically requiting only 2 grids perwavelength.

传统的电磁场数值算法——时域有限差分法稳定而易于实现，但由于FDTD采用中心差分近似Maxwell旋度方程的微分，每个波长上需要取的网格数通常较多，而时域伪谱法采用伪谱法求微分，理论上每个波长只需要取两个网格便可以达到较高的精度。

However, because the measuring process is influenced by many factors, it is difficult to improve the accuracy of dynamic measurement. It is the focus of the measurers and the designers all through the ages. Thus, the research on dynamic error and accuracy theory is always heavily concerned.

由于动态测量的影响因素较多，如何提高其测量精度，一直是工程测量与仪器设计人员关注的重点，因而，对动态误差与精度理论的研究也历来受到人们的重视。

Laser-based metrology and grating-based metrology are two main ultra-precision tools of dimension measurement. However, very few research work has been done on grating-based nanometrology compared with laser-based nanometrology till now because many people, including some grating researchers and specialists, hold the idea that the accuracy of grating-based measurement is lower than the laser's and can only reach micrometre or sub-micrometre level. They consider that it is unfeasible to get nanometer-scale accuracy using grating-based sensors.

激光技术和光栅技术是毫米级以上量程的精密几何量测量的两种最主要手段，目前，用激光进行纳米测量的研究已经很多，但光栅纳米测量技术的研究却很少；很多人，包括很多光栅研究者和测量专家，都认为，光栅测量的精度不如激光，其精度还只是停留在微米量级上，用光栅来进行更高精度的测量以至纳米测量是难以实现的。

In order to verify the accuracy of the modeling built by ANSYS and the precision of the analytical results, the modelings of both rotor and motor are experimented at same time.
