Research on Forward Problem of Tuber Electrical Resistance Tomography System

摘要：

　　Electrical resistance tomography (ERT) has the advantages of low cost, non-invasion, no radiation and visualization, and it is a hot research topic in the industrial process tomography (PT).The ERT technology applied to the agriculture is a new research field, which can be used in the crop growth status monitoring, new varieties nurturing and fine cultivation of plants.In the paper, the working model of ERT under the condition of soil environment is studied; the sensitive field model is established and simulated by using COMSOL software.The affects brought by different excitation/measurement with different soil conductivity are studied in detail.The research can provide the significant guidance for the further study of backward problem in tuber ERT system.
