“…In addition, the details of island interaction before and during a (minor) disruption are still not very clear. In the future, this interaction would be studied by using 2D electron cyclotron emission imaging (ECEI) and auxiliary heating, such as electron cyclotron resonance heating (ECRH) [33]. The ECEI could help to observe the evolution and interaction of magnetic islands and contribute to the understanding of disruption phenomena like KSTAR [18].…”

Behavior of multiple modes before and during minor disruption with the external resonant magnetic perturbations (RMPs) has been studied on J-TEXT tokamak. The main component of RMPs is m/n = 2/1, where m and n are the numbers of the poloidal and toroidal mode, respectively. During the mode locking caused by RMPs, it is found that before a minor or major disruption (if there is no minor disruption), strong oscillations in both electron temperature and density occur if the edge safety factor qa > 3. The analysis shows that the oscillations are caused by the m/n = 3/1 mode. In addition, using the ECE, Mirnov coils and 2D electron cyclotron emission imaging (ECEI) diagnostic systems, it is found that a thermal collapse occurs on the inner side of the 2/1 magnetic island during the minor disruption, and before the collapse, a 3/2 island increases, after the collapse, the 3/2 island may disappear. Moreover, the study also shows that these 3/1, 2/1 and 3/2 modes play roles in the thermal collapse of disruptions.

With the continuous improvement of international influence, the foreign economic and cultural exchange activities of Chinese cities are increasing day by day. Based on the micro learning experience, this paper studies the text reconstruction of city publicity translation from a cross-cultural perspective. Taking the publicity translation of Nanchang as an example, this paper makes a text reconstruction translation of Brief Introduction of Nanchang City. First of all, the attitude of domestic netizens towards city publicity was investigated. 41.5% of netizens thought that city publicity was very necessary, and most netizens could realize the purpose and role of city publicity. After the release of Nanchang foreign publicity video, 26.2% of the foreign audiences who watched the video said they fully understood the content of the video, and Nanchang's topic popularity on the Internet increased significantly. This shows that the cross-cultural text reconstruction of urban publicity translation based on micro learning experience can effectively improve the effect of publicity and expand the influence of the city.

With the development of GNSS and the application of multimode signals, efficient GNSS receiver research has become very important. However, threat signals in the received signal are inevitable, which will represent important threats to navigation applications and will lead to leakage and fault detection for the receiver. Therefore, the searches with threat prediction in GNSS signals have been regarded as the important problem for GNSS receivers. In view of the limitations and nonadaptability of the current search technologies as well as on the basis of the proportionality peak judgment mechanism, a dynamic search mechanism with threat prediction (DSM-TP) is proposed in this paper, in which we define a series of preset coefficients and a threat index to optimize the decision mechanism. The simulation results demonstrate that the DSM-TP method can predict the threat situation and can adapt to lower SNR environments compared to the traditional method. In addition, the DSM-TP method can avoid the impact of threats, and the detection capability of the new method is better than the detection capability of the traditional method.
