It can be controlled dynamically by a classical external field threading the SQUID within the charge qubit. Utilizing the controllable quantum entanglement, we can demonstrate the dynamic process of the quantum storage of information carried by charge qubit. On the other hand, based on this engineered quantum entanglement, we can also demonstrate a progressive decoherence of charge cubit with quantum jump due to the coupling with the cavity field in quasi-classical state.展开更多

In this paper, according to the test results of the residual stress obtained in the production process, combined with some data, the process is divided into stages and situations, the change of residual stress and its cause in the whole process of rolling are analyzed. The surface state of roller is different. According to my own experience, some suggestions are put forward for the treatment of stress surface to be measured. By analysis, the factors of producing residual stress in roller production can be summarized as: irregular elastic-plastic deformation, irregular temperature change and irregular phase transition. In many cases, the formation of residual stress is the result of the combined action of many factors. By analyzing which kind of stress occupies the dominant position, we can control the residual stress to be harmful for the benefit of improving product quality.展开更多

Under this premise, the difficulty of the geological exploration of the hydraulic ring is further increased. The purpose of exploration is to understand the geology and water quality of an area. In order to undertake the important task of exploration and give consideration to environmental protection, it is necessary to continuously optimize the exploration technology and perfect the exploration system. Therefore, this document first clarifies the basic content of water environment geological exploration, then analyzes the relationship between exploration environment and exploration, and puts forward suggestions for optimizing and improving water environment geological exploration, which will provide more help for promoting the development of ecological civilization and improving the quality of water environment geological exploration in our country.展开更多
