太阳空间探测在太阳物理前沿科学问题研究和空间天气预报应用研究方面具有重要的意义.人类在60余年的太阳空间探测活动中,取得了一系列重要成果,但仍存在诸多根本性重大问题有待解决.太阳立体探测可以克服单视角观测的局限,获取全方位、多要素的物理数据,促进解决太阳物理中的重大科学问题.本文介绍了太阳内部结构和磁场起源、太阳活动机理研究、太阳活动的全日球空间天气效应和空间天气预报模式研究4个科学目标,太阳立体探测任务空间布局、系统组成和探测器总体设计,以及太阳立体探测任务的有效载荷配置和主要技术指标.

Fast radio bursts(FRBs) are highly dispersed millisecond-duration radio bursts,[1,2]of which the physical origin is still not fully understood. FRB 20201124A is one of the most actively repeating FRBs. In this paper, we present the collection of 1863.burst dynamic spectra of FRB 20201124A measured with the Five-hundred-meter Aperture Spherical radio Telescope(FAST). The current collection, taken from the observation during the FRB active phase from April to June 2021, is the largest burst sample detected for any FRB so far. The standard PSRFITs format is adopted, including dynamic spectra of the burst, and the time information of the dynamic spectra, in addition, mask files help readers to identify the pulse positions are also provided. The dataset is available in Science Data Bank, with the link https://***/10.57760/sciencedb.j00113.00076.

The observation of short gamma ray bursts(SGRBs)in the TeV energy range plays an important role in understanding the radiation mechanism and probing potential new physics,such as Lorentz invariance violation(liV).However,no SGRBs have been observed in this energy range owing to the short duration of SGRBs and the weakness of current *** experiments with new technology are required to detect the very high energy(VHE)emission of *** this study,we simulate the VHE γ-ray emissions from SGRBs and calculate the annu-al detection rate with the High Altitude Detection of Astronomical Radiation(HADAR)***,a set of pseudo-SGRB samples is generated and checked using the observations of the Fermi-GBM,Fermi-LAT,and Swift-BAT *** annual detection rate is calculated from these SGRB samples based on the performance of the HADAR *** a result,the HADAR experiment can detect 0.5 SGRBs per year if the spectral break-off of γ-rays caused by the internal absorption and Klein-Nishina(KN)effect is larger than 100 *** a GRB090510-like GRB in HADAR's view,it should be possible to detect approximately 2000 photons considering the internal absorption and KN *** a time delay assumption due to liV effects,a simulated light curve of GRB090510 has evident energy *** hope that the HADAR experiment can perform SGRB observa-tions and test our calculations in the future.
