Abstract: A method and system of two-point correction based on temperature substitution, includes: a black body related to the lens temperature is arranged outside a lens, a first black body arranged in front of the lens of an infrared thermal camera, so as to collect a gray value of the first black body; a temperature of the first black body being equal to the lens temperature; a second black body arranged in front of the lens of the infrared thermal camera, so as to collect a gray value of the second black body; a temperature of the second black body being higher than the lens temperature. Two correction parameters obtained by black body calculation related to temperature are strongly applicable, which eliminates the problem of image quality deterioration caused by temperature changes and greatly eliminates the pot lid phenomenon due to non-uniformity, thereby accurately calculating the corrected gray value.

Abstract: A network emulation system supporting a flexible and efficient dynamic experiment emulates a network based on container, veth-pair, traffic control (TC), and other technologies and sets a network state management model based on a key-value pair, thereby constructing a network emulation system supporting a flexible and efficient dynamic experiment. The system flexibly realizes the dynamic performance of a plurality of dimensions, namely, dynamic node start/stop, dynamic node attribute configuration, dynamic link start/stop, and dynamic link attribute configuration. Based on the network state management model, the network emulation system provides a concise and unified dynamic application programming interface (API) for an upper layer. Researchers can call the API in their network innovation programs at any time after an emulation network is deployed to achieve efficient, batch-processing, and programmable dynamic management. The network emulation system greatly facilitates the experimental work of the researchers in a dynamic scenario of the network.

Abstract: A method of reducing or rejecting common mode interference and a circuit for electromagnetic induction logging with improved common mode interference reduction or rejection are disclosed, which are useful in the field of electromagnetic induction logging technology. Accurate formation signals are calculated based on phases and amplitudes of common mode signals, which do not change with the coil access mode, and phases of differential signals, which are reversed with amplitudes unaltered when the coil is connected reversely. This provides a mechanism to effectively eliminate the influence of common mode interference even when the common mode interference is greater in amplitude than the signals from a geological formation.
