sampling structure造句

Study of rf direct bandpass sampling structure of software radio amp; amp; its use
射频直接带通采样软件无线电结构分析及其应用
Although reducer can avoid step sense and oscillation partly , the strap transmission will influence orientation precision ( it is key norm to the small metallographic sample cutting machine ) , so plan to use step motor to drive the screw directly , the step motor at low velocity , which is not drived by the subdividing drive system , will have obvious oscillation and noise that would influence the cutting function , the usage life and sample structure
由于步进电机是通过皮带轮减速来驱动丝杠，进而带动砂轮片前进和后退，虽然减速能部分消除步进感和振动，但皮带传动会影响定位精度，定位精度对精密切割机十分关键的技术指标。采用步进电机直接驱动丝杠，未经细分驱动的步进电机在低速运行时，有明显的步进感、振动和噪声，从而对切割的性能、砂轮片的使用寿命、试样的组织结构产生较大的影响。
