超声频率一致性分析及其在缺陷分类中的应用 - The third chapter in the paper presents a method that we can select suitable ultrasonic frequence in the analysis of the ultrasonic attenuation
在论文第四章对超声波在液压缸中衰减的分析中提出了选择合适超声频率的一种方法。 - The ultrasonic dynamic contact of bolt - clamped transducer and rigid plane are modeled using hertzian contact theory , and the analyzing results reveal that the nodal plane of the bolt - clamped transducer is levitated in normal direction by the ultrasonic dynamic contact action , and the real area of contact of bolt - clamped transducer and rigid plane decreases in the same time
首先利用赫兹接触理论建立了夹心式换能器和刚性平面的超声动态接触模型。通过对模型进行分析、求解表明,在纵向超声频率动态接触作用下,换能器节面位置产生了上浮,换能器端面与刚性平面的动态真实接触面积比静态时减少了。 - Changes of the longitudinal and transversal wave velocities in different directions and the rock velocity anisotropy as a function of confining pressure have been studied under laboratory ultrasonic frequency for shale and sandstone with marked foliation , which had been saturated by the fluids with different viscosity kerosene and vacuum pump oil and salinity distilled water , 50000
利用不同黏度煤油和真空泵油不同矿化度蒸馏水50mg l和150mg l的nacl溶液的流体对页岩和具有明显层理的砂岩进行饱和，在实验室超声频率下研究样品不同方向纵横波速度以及各向异性参数 - The factors include ultrasonic wave frequence , condition temperature , ultrasonic converter instrinisic system error , hareware extended time , electricity noise and sonic noise in the spot , city power defmcient pressure and exceeded pressure , city power peak and pour . we adopt the following compensation schemes of error in the system . about ultrasonic wave frequence ' s effect to measurement precision , we can choose appropriate frequence according to the measured distance
在空气和液压缸中影响测距精度的主要因素包括：超声波的频率、环境温度、超声换能器本身的系统误差(即探头固定误差) 、硬件时间延迟、工作现场的电噪声和声噪声、市电的过压、介压噪声以及市电的尖峰和浪涌噪声，在本系统中采取了以下几种误差的补偿方案： ?对于超声波的频率对测量精度的影响，只能根据测距的距离选择合适的超声频率。
