An approximate imaging algorithm based on integral equations for three-dimensional anomalous conductivities on the transmitter-receiver profile was developed in consideration of the limited information from the cross-hole electromagnetic measurements so far available.
考虑到井间电磁测量信息量的局限性,基于积分方程在发射接收剖面对三维电导率异常体进行近似成像。
Based on the simplified mechanical model of beam-to-column T-connections of steel frame, a nonlinear mathematic model was proposed to predict the M-θ r? relations by use of the known sizes of the connections.
根据钢框架梁柱剖分T型钢连接节点的简化力学模型,提出一种用已知节点尺寸来预测其Mθr关系的非线性数学模型,模型中的主要参数是节点初始转动刚度和极限承载力。
