查询词典 accuracy

The Additional Guide Star (with star flag 5) is come into use for improving the accuracy and speed of star identification. After the cases analysis of unsuccessful star identification, giving the guide star which always cause false star identification a given star flag(such as 6), which denote that the star is a Redundant Guide Star and can't take part in the star identification processing. Through the introduction of Redundant Guide Star, the accuracy of star identification is improving. The distribution of Additional Guide Stars spread all over the whole sky, even the star sparse area.

在选取导航星的过程中，位置精度阈值的引入，使得高精度的恒星作为导航星，为高精度的卫星姿态反演奠定了基础；辅助导航星的引入，与单一使用Tycho-2星表相比引入了大量的亮星(189颗辅助导航星遍及全天球，其中亮于3等星的恒星占34.4%)，且弥补了部分天区恒星稀疏无法满足星图识别条件的不足，这将十分有利于提高星图识别速度和识别率；冗余导航星的剔除，为进一步提高星图识别率提供了可能。

Illegal information delivery vio-lates the lawin the aspects of truth,accuracy,justice,time and legal responsibility,and the subject of responsibility should be those have influence over the information delivery in the aspects of truth,accuracy,justice,time and legal responsibility,who will not take th...

而这些责任主体并不必然最终承担责任，须考虑主观因素。按照证券市场上信息披露主体的多元性以及对信息披露所尽义务的不同，对责任主体应分别采取无过错责任原则和过错推定原则来确定其最终是否承担责任。

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. After the comparisons of the numeric analysis results, experimental values are the foundation to consider the physical meanings and to suitably modify the modeling in order to decrease the differences between both results, to obtain the correct modeling type, to increase the analysis accuracy, and to provide designers a reliable basis.
