The paper discusses the relation of the bubble pressure and the filtering ratio of filtering medium ( filter). 本文论述了冒泡压力和过滤介质(芯)过滤比这两个不同定义概念的关系。
Rational Bubble in Efficient Stock Markets and the Information Filter of Stock Value 有效证券市场的理性泡沫与股票内在价值的信息滤波
Studies on Bubble Pore Size and Diameter Distribution of Rigid Porous Filter Media ( Part ⅱ) 硬质多孔过滤介质鼓泡孔径及孔径分布的测定研究(Ⅱ)
Removing effects of bubble pulses of explosive charge by shaping filter 用成形滤波器消除水下脉冲声源气泡效应的研究
According to the theory of traditional bubble system, this paper design a new type of water level remote measure system aiming at the present situation of water level automation measurement, adopting travel wave filter technique and quartz crystal pressure sensor with high accuracy and stability. 针对水位测量自动化发展现状,依据传统的气泡系统理论,采用高准确度、高稳定的石英晶体压力传感器,利用运动波滤波技术,设计了一种新型的水位监测系统。
Make use of the band-pass filter characteristics of HHT, effective filter for bubble flow, slug flow, churn flow and annular flow were achieved. The results show that after filter, signal can keep good local character and nonlinear element. 2. 该滤波方法利用HHT的带通滤波特性,实现对泡状流、弹状流、塞状流、混状流差压信号有效滤波,滤波后可以很好的保留两相流差压信号的非线性特征。
