Application of ultrasonic wave in condensate critical flowing saturation testing 超声波在凝析油临界流动饱和度测试中的应用
At the end of this paper, the conclusion is, the saturation of testing instruments or the limitation of the equipment have no effect upon detection of weak periodical signals by the method of the cycle-weighted-correlation. 并给出结论:当用循环加权自相关提取淹没在强平稳随机噪声中的周期性信号时,不受机械装置的限幅或测试仪器饱和特性的影响。
The results show that it is possible to evaluate the attenuation characteristics of landslide soil with semi-quantification method, and the parameter values are not less than low values of saturation testing usually. 研究结果表明:工程年限内在综合考虑影响滑带土因素的基础上,对滑带土参数的衰减特性可进行半定量评价,其值一般不会低于饱和直剪试验低值。
