A Confined Two-peaked Solar Flare Observed by EAST and SDO     

Liang Zhang  Ruisheng Zheng  Zhike Xue  Changhui Rao  Qing Lin  Zhimao Du  Jiawen Yao  Libo Zhong  Yao Chen 《天文和天体物理学研究(英文版)》2024,(4):73-85

The solar flare is one of the most violent explosions, and can disturb the near-Earth space weather. Except for commonly single-peaked solar flares in soft X-ray, some special flares show intriguing a two-peak feature that is deserved much more attentions. Here, we reported a confined two-peaked solar flare and analyzed the associated eruptions using high-quality observations from Educational Adaptive-optics Solar Telescope and Solar Dynamics Observatory. Before the flare, a magnetic flux rope(M...  相似文献   

Formation and evolution of the South China Sea since the Late Mesozoic: A review     

Xue-jie Li  Zhe Wang  Yong-jian Yao  Hong-fang Gao  Song Zhu  Zi-ying Xu 《China Geology》2023,6(1):154-167

The existing genetic models of the South China Sea(SCS) include an extrusion model of the Indochina Peninsula, a back-arc extension model, and a subduction and dragging model of the Proto-South China Sea(PSCS). However, none of these models has been universally accepted because they do not fully match a large number of geological phenomena and facts. By examining the regional tectonics and integrating them with measured data for the SCS, in this study, a back-arc spreading-sinistral shear model ...  相似文献   

Quality influencing factors of dispersion curves from short period dense arrays based on a convolutional neural network across the north section of the Xiaojiang fault area          下载免费PDF全文

Si Chen  Rui Gao  Zhanwu Lu  Yao Liang  Wei Cai  Lifu Cao  Zilong Chen  Guangwen Wang 《地震科学（英文版）》2023,36(3):200-211

The number of dispersion curves increases significantly when the scale of a short-period dense array increases. Owing to a substantial increase in data volume, it is important to quickly evaluate dispersion curve quality as well as select the available dispersion curve. Accordingly, this study quantitatively evaluated dispersion curve quality by training a convolutional neural network model for ambient noise tomography using a short-period dense array. The model can select high-quality dispersio...  相似文献   

PyMsOfa: A Python Package for the Standards of Fundamental Astronomy(SOFA) Service     

Jianghui Ji  Dongjie Tan  Chunhui Bao  Xiumin Huang  Shoucun Hu  Yao Dong  Su Wang 《天文和天体物理学研究(英文版)》2023,(12):186-191

The Standards of Fundamental Astronomy(SOFA) is a service provided by the International Astronomical Union that offers algorithms and software for astronomical calculations, which was released in two versions for FORTRAN77 and ANSI C, respectively. In this work, we implement the Python package PyMsOfa for SOFA service by three ways:(1) a Python wrapper package based on a foreign function library for Python(ctypes),(2) a Python wrapper package with the foreign function interface for Python callin...  相似文献   

Collaborative Simulation of Mechanical Structure and Control Systems of Leighton Chajnantor Telescope     

Yi-Wei Yao  Wei-Rui Chen  Zheng Wang 《天文和天体物理学研究(英文版)》2023,(4):135-149

Leighton Chajnantor Telescope(LCT) will be moved from the summit of Maunakea, Hawaii to Chajnantor Plateau, Chile and be refurbished there. Strong wind disturbance at the new site will bring great challenges to the servo control of LCT. It is necessary and important to develop a simulation platform that behaves as close as possible to the real telescope for testing the performance of the designed servo controller. In this paper, a collaborative simulation platform of LCT based on Adams and Matla...  相似文献   

CLIMATIC CHARACTERISTICS OF ATMOSPHERIC NET RADIATION OVER CHINA_*     

Weng Duming  Gao Qingxian  Yao Zhiguo 《Acta Meteorologica Sinica》1997,11(2):246-254

In terms of ERBE and ISCCP data.and measured/calculated surface net radiation,computation is performed of the climatic characteristics of ANR(atmospheric net radiation) across China alongside with the discussion and relations to other two kinds of radiation and contributing factors.Evidence suggests a high linear correlation of ANR with atmosphere-absorbed shortwave radiation.whereby can be established a general expression for ANR,which decreases more sharply as a function of altitude and increases slightly with latitude in summer,and changes uniformly in winter.Eventually,a comparison is made of the findings presented in this paper and literatures regarding the ANR pattern and magnitudes,indicating their great difference.  相似文献

Transport patterns of micro nutrient elements from the continental shelf of the East China Sea to the Kuroshio area     

Lu Saiying  Yao Qiao''er  Chen Zhen 《海洋学报(英文版)》1992,11(2):219-230

On the basis of the in situ data of DO2, pH, SiO2. PO4-P, NO3-N and NO2-N collected in the north of the East China Sea during 1987-1988, the following points are mainly expounded.1.The inorgonic nutrients are obviously affected by continent runoff in the north of the East China Sea. Their distributions are characteristic of its distribution of terrigenous materials.2.There are three transport paths of nutrients from the shelf to the Kuroshio area. The first is mixing-diffusing-advec-tion and upwelling process, the process of biology and biochemistry belongs to the second, and the sinking process is the last one.3.The swing of the Kuroshio axis affectes both the range of the migration of substances through mixing-diffusing-advec-tion process and the upwelling degree of the subsurface Kuroshio water to the shelf.4.Most part of the substances sink as macroparticles to the deep layer before reaching the Kuroshio area.  相似文献
