| 1 | 电学层析成像中软场效应的度量与应用显示文摘'软场效应'的存在导致电学层析(ET)成像技术重建图像分辨率低,为了度量'软场效应'并降低其影响,提出了一个基于灵敏度系数的'软场效应'度量指标,据此实施ET测量数据的重构。实验结果表明:软场效应指标能够有效地反映'软场效应'对ET成像空间分辨率的影响,重构的数据能够提高已有ET算法的空间分辨率。 | 杨家辉 岳士弘 于晓 | 2017 | 传感器与微系统2017，36，7： | 1 |
| 2 | Particle size influence on effective permittivity of particle-gas mixture with particle clusters显示文摘The influence of particle size on the effective permittivity of a particle-gas mixture in the presence of particle clusters was studied using numerical analysis involving the three-dimensional finite element method.The effective permittivity of the mixture was obtained by calculating the electrostatic energy generated in the computation domain.Numerical results show that for fixed volume fraction of particles in the mixture,the effective permittivity of the mixture increases with decreasing particle size.Static experiments were carried out by using a differential capacitance sensor with parallel plates.The variation of the effective permittivity with particle size is shown by experimental data to agree with the numerical results.The methodology described and the results obtained in this paper may be used to help modify the measurement of particles volume fraction in the presence of particle clusters when a capacitance sensor is used. | Lijun Xu Chang Liu Zhang Cao Xiaomin Li | 2013 | Particuology2013，11，2： | 1 |
| 3 | Distribution characteristics of holdups in a multi-stage bubble column using electrical resistance tomography显示文摘Based on the principle of chemical reaction engineering,the addition of perforated plates can improve the performance of conventional bubble column and decrease the backmixing behaviors.The distribution characteristics of gas holdup in a multi-stage bubble column embedded with five types of sieve plates and three types of tongue plates were studied using electrical resistance tomography(ERT).The effects of superficial gas velocity and the geometric design of perforated plates on the gas holdup and its radial distribution above and below the plates of the bubble column were discussed.Experimental results show ERT is suitable as an online monitoring tool to provide useful information on the hydrodynamic parameters of multi-stage bubble columns.With increasing superficial gas velocity,local gas holdup increases,and gas holdup below the plate increases with decrease of free area(%FA),hole diameters or angle of tongue plates.ERT technique facilitates noninvasive and nonintrusive visualization of cross-sectional distribution of gas holdup in a bubble column. | Haibo Jin Yicheng Lian Yujian Qin Suohe Yang Guangxiang He | 2013 | Particuology2013，11，2： | 1 |
| 4 | 油气润滑ECT系统灵敏度矩阵的秩亏问题及其影响因素显示文摘建立了油气润滑ECT系统图像重建的数学模型和仿真模型,定义了秩亏数和相对秩亏率,分析了油气润滑ECT系统灵敏度矩阵产生的秩亏问题及其影响因素,结果表明:在忽略软场效应的条件下,灵敏度矩阵的秩亏随极板数的增加而减小,随油膜厚度的增加而增大;在计入软场效应的条件下,灵敏度矩阵的秩亏仍然随极板数的增加而减小,随油膜厚度的增加而增大,但系统灵敏度矩阵的秩亏将减小,油气润滑ECT系统图像重建时产生秩亏的根本原因是检测数据的不足。 | 李照威 孙启国 | 2021 | 内蒙古科技与经济2021，，8： | 0 |
