 benchmark
 Study of the Applications of the Benchmark System to the Stamping Dies for the Auto Body 车身冲模基准体系的应用研究 短句来源 During the measurement of blade by coordinate measuring machine, the benchmark of design and measuring is not the same, so it is necessary to transfer the measuring model to the CAD model for comparison. 在三坐标测量机的测量中,由于叶片的测量基准与设计基准不一致,测量坐标系统与设计坐标系统之间必须经过转换,即叶片的测量模型和CAD模型的基准必须一致,才能够比较测量数据,因此叶片的定位校准必不可少。 短句来源 A Instrument for Measuring Symmetry of Keyway in the Hole Based on Benchmark Changing 基于基准互换的孔内键槽对称度检测量具 短句来源 Study of Employing Air Film's Character of Averaging Flatness Error to Improve the Precision of Measuring Benchmark 利用气浮均化技术提高测量基准精度的研究 短句来源 The benchmark contains the error. 因此,在形位误差测量中,基准件的精度高低直接影响着测量的结果。 短句来源 更多

(2) According to the actual developing experience, five modeling principles of CNC machine tools part based on Pro/E----whole modeling principle, the same reference base principle, symmetry modeling principle, bepainting principle and confining the size of file principle are summarized. (2) 根据实际开发经验总结了基于Pro/E的数控机床部件的五个建模原则——整体建模原则、相同参考基准原则、对称建模原则、着色原则、限定文件大小原则，提高了Java 3D中导入模型的建模效率。 短句来源 To measure a cam, we must unify the designing and measuring base of a cam lift, and then use the“minimum condition”method to confirm the center line of a cam. 凸轮测量必须解决设计基准与测量基准的统一问题,否则凸轮设计基准相对于测量安装基准的偏心和凸轮轴的弯曲都进入了测量结果,从而引入较大的测量误差。 短句来源 When a cam is measured, if the designing and measuring base of cam lift having not been unified, the offset of designing and fixing base would be added to the measuring result, a bigger system error would be brought to the cam lift. 凸轮升程测量的关键点是确定凸轮中心线。 常用的确定凸轮中心线的方法如“敏感点”法、“最高点”法和“敏感段”法等方法都不能实现测量基准与设计基准的统一,而且不能满足最小条件要求,会给凸轮升程测量带来较大的系统误差。 短句来源 更多

 reference
 The authors extend and improve some known results, and show that there are some errors in reference on inequalities for sequence rearrangement by examples. The blank reference experiment shows that hydrothermal crystallization treatment favors the formation of hexagonal tungsten trioxide, and the tungsten trioxide powder sample prepared by this method has a high degree of crystallinity. This paper provides a reference on calculating the binding-site number in proteins for ligands and studying their interactions by fluorescence spectroscopic methods. The proposed algorithm can easily identify which sector the reference space vector falls in and conduct simple operations to find the duty cycle of each vector. The similar parts in MANET routing protocol are used in the satellite network for reference. 更多
 datum
 We use this approach together with the new datum in order to investigate its implications for the baryon spectrum. The Vallesian lower boundary and "Hipparion-datum" are estimated as ranging in age from 11.2 to 10.7 Ma in Central to Western Europe and Western Asia. The geometrical accuracy of a machined feature on a workpiece during machining processes is mainly affected by the kinematic chain errors of multi-axis CNC machines and robots, locating precision of fixtures, and datum errors on the workpiece. A mapping model between the displacements of workpieces and the datum errors, and adjustments of fixtures is established. The life-test datum with an accumulative count about 1011 is obtained; the structure and composition of active surface of fatigued CEM are analyzed by using AES. 更多
 benchmark
 The numerical simulations on several benchmark problems show that the scheme is very efficient. The test by some benchmark problems shows that the proposed algorithm achieves relatively higher performance. Experimental results for MCNC benchmark circuits are given. All this is supported by the experimental study on benchmark circuits. The experimental results with the adaptive control on the "Helicopter" benchmark were described. 更多
 base
 Geometric construction of the global base of the quantum modified algebra of However the compatibility of the canonical base of the modified algebra and of the geometric base given by intersection cohomology sheaves on the affine flag variety was never proved. We prove that these determinantal semi-invariants span the space of all semi-invariants for any quiver and any infinite base field. For $\gamma\in\mathbb{R}$ let $C(\gamma)$ be the set of all $f\in{\mathcal S}^\prime$ for which$\sum_{n=0}^{\infty}\,|(f,h_n)|\,(n+1)^{\gamma}>amp;lt;\infty$, where $(h_n)_{n=0,1,\dots}$ is the orthonormal base of Hermite functions. A gene regulatory mechanism has been proposed in which steroid hormones and certain other drugs bind to nuclear receptor proteins followed by transfer to DNA where they are inserted between base pairs. 更多
