After analyzing the figures of frequency spectra,and comparing them with the results measured with the way of eliminating elements,The main noise source was precisely determined,which was the pair of gears meshing abnormally in the transmission system of the nachine. So the approach of reducing the noise of he machnine was found.     用FE—3000型磁带机对磨粉机噪声作实时记录,在7T08处理仪上对所记录之噪声进行频谱分析,并用消元法作对比,准确地找到了该机的主要噪声源是其传动系中的一对非正常啮合的齿轮,从而为该机的降噪处理指明了方向。 短句来源 查询“tape recorder”译词为用户自定义的双语例句     我想查看译文中含有：的双语例句 为了更好的帮助您理解掌握查询词或其译词在地道英语中的实际用法，我们为您准备了出自英文原文的大量英语例句，供您参考。   tape recorder Microtremor observations at 59 stations in the Akita plain in Japan were carried out during November 23 through November 28, 1969 using magnetic tape recorder. 例句来源       An experimental situation is then treated; system-component models are developed for the digitizer, tape recorder, filter, transducer and mechanical structure. 例句来源       The application of a digital computer and analog tape recorder for the complete task of data acquisition and reduction is discussed. 例句来源       The Interkosmos5 VLF experiment consisted of a spectrum analyser with twelve narrow-band channels and broadband measurements between0.07 and20 kHz using an analogue telemetry with a tape recorder on board. 例句来源       Data capacity of a channel containing a tape recorder 例句来源       更多                    This paper describes the noise testing results of Type 6F—1820 flour milling machine.The noise signals of the machine were recorded with the FE—3000 tape recorder,and analyzed for frequency spectralqs urpose by means of 7T08 signal Processor.After analyzing the figures of frequency spectra,and comparing them with the results measured with the way of eliminating elements,The main noise source was precisely determined,which was the pair of gears meshing abnormally in the transmission system of the...             本文介绍对南阳产6F—1820型磨粉机噪声的测试结果。用FE—3000型磁带机对磨粉机噪声作实时记录,在7T08处理仪上对所记录之噪声进行频谱分析,并用消元法作对比,准确地找到了该机的主要噪声源是其传动系中的一对非正常啮合的齿轮,从而为该机的降噪处理指明了方向。 文摘来源          The friction behaviour between the felt and damping plate (its material is polyformaldehyde) in the video tape recorder is discussed. There are kinds of techniques for measuring the friction torque and the friction coefficient. This paper suggests a very simple and effective tribo-testing device which can dynamically measure the friction torque and the friction coefficient between the felt and the damping plate. Through many experiments the curve of the friction torque varying with the specific ...             本文讨论了磁带录象机中毛毡与阻尼盘(材料为聚甲醛)间的摩擦特性,提出了一种极其简便、有效的动态测量毛毡与阻尼盘间的摩擦力矩和摩擦系数的测试装置,并在此装置上进行了大量的试验,得出摩擦力矩随比压的变化曲线和摩擦系数随比压增加而下降的结论,导出了摩擦系数随比压变化的经验公式。 文摘来源          This study investigates different characteristics of the fluctuating pressure induced by a conventional propeller (without skew) and ahigh skewed propeller in two specified flow field (symmetrical and unsymmetrical) and the effect of the skew on the reduction of the fluctuating pressure. The sensor and the data processing system for the measurement of fluctuating pressure are introduced. This so called Multi-Function System based on the design idea of "quick" sampling and storing data and "slow" transmittin...             本研究通过普通螺旋桨(无侧斜)和大侧斜螺旋桨在空泡水洞两个特定流场(对称非均匀流场和不对称非均匀流场)中诱导的脉动压力试验测量,探讨其不同的脉动压力特性和侧针的减振效果;介绍了为测量脉动压力而建立的传感器和数据采集处理系统。这一根据高速采集储存数据、慢速传送微机处理思想建立起来的Molti-Function系统,有别于通常采用的由高速处理机和磁带记录机组成的脉动压力数据采集处理系统,具有数据采样速度快,无信号失真等优点。本研究发现,大侧斜桨具有降低螺旋桨空化诱导的脉动压力幅值作用,但这一作用的大小与空化数和流场特徵有关;无论是普通桨还是大側斜桨,在不均匀流场中诱导的脉动压力均具如下特徵,即与一阶叶频谐调分量相比,在较大空化数情况,二阶以上叶频谐调分量明显丰富,而在较小空化数情况,则明显变小。本研究认为,在应用简化网格模拟得到的不均匀流场中进行螺旋桨脉动压力测量的比较试验,可克服模拟流场差异带来的测量结果误差,有助于提高实验室的脉动压力测试技术水平。 文摘来源   << 更多相关文摘         相关查询: digital tape recorder stereo tape recorder bandspread tape recorder perforated tape recorder data tape recorder a tape recorder video recorder tape magnetic tape recorder seismograph tape recorder cassette tape recorder video tape recorder digital cassette tape recorder  对查询结果不满意
