| 1 | Space Astronomy in China: 2002-2004显示文摘More and more proposals, or potential projects have been proposed in recent two years. We try to briefly outline these new proposals, although most of them are in fact only in their conception studies. The progress of previously mentioned projects, like Space Solar Telescope (SST), the Hard X-ray Modulation Telescope (HXMT), as well as newly initiated LUnar Resource Explorer (LUREX), will be introduced elsewhere. | GAN Weiqun XUE Suijian | 2004 | 空间科学学报2004，24，z1： | 10 |
| 2 | Space Astronomy in China During 2004 - 2006显示文摘For the past two years, some real progress has been made in Chinese Space Astronomy, though we have not launched any missions exclusively belonging to the scope of Astronomy. In order to program the next five years' national plan (2006-2010), the Chinese Space Agency organized a series of authorized evaluations for the future missions. Among more than ten astronomical mission proposals, several were selected to give the green light to continue for their Phase A studies. We try to briefly outline these proposals. | GAN Weiqun | 2006 | 空间科学学报2006，26，z1： | 8 |

| 11 | SMESE: A French-China Joint Solar Mission显示文摘SMESE (SMall Explorer For the study of Solar Eruptions) is a Franco-Chinese Microsatellite mission. The scientific objectives of SMESE are the study of coronal mass ejections and flares. Its payload consists of three instrument packages: LYOT, DESIR and HEBS. LYOT is com-posed of a Ly-α (121.6 nm) coronagraph, a Ly-α disk imager and a far UV disk imager. DESIR is an infrared telescope working at 35μm and 150μm. HEBS is a high energy burst spectrometer working in X-rays and γ-rays covering the 10keV to 600 MeV range. SMESE will be launched around 2011, providing a unique opportunity of detecting and understanding eruptions at the maximum activity phase of the solar cycle in a wide range of energies. | CHANG Jin GAN Weiqun | 2006 | 空间科学学报2006，26，z1： | 2 |
| 12 | On the error analyses of polarization measurements of the white-light coronagraph aboard ASO-S显示文摘The Advanced Space-based Solar Observatory(ASO-S) mission aims to explore the two most spectacular eruptions on the Sun: solar flares and coronal mass ejections(CMEs), and their magnetism.For the study of CMEs, the payload Lyman-alpha Solar Telescope(LST) has been proposed. It includes a traditional white-light coronagraph and a Lyman-alpha coronagraph which opens a new window to CME observations. Polarization measurements taken by white-light coronagraphs are crucial for deriving fundamental physical parameters of CMEs. To make such measurements, there are two options for a Stokes polarimeter which have been applied by existing white-light coronagraphs for space missions. One uses a single or triple linear polarizer, the other involves both a half-wave plate and a linear polarizer. We find that the former option is subject to less uncertainty in the derived Stokes vector propagating from detector noise.The latter option involves two plates which are prone to internal reflections and may have a reduced transmission factor. Therefore, the former option is adopted as our Stokes polarimeter scheme for LST. Based on the parameters of the intended linear polarizer(s) colorPol provided by CODIXX and the half-wave plate 2-APW-L2-012 C by Altechna, it is further shown that the imperfect maximum transmittance of the polarizer significantly increases the variance amplification of Stokes vector by at least about 50% when compared with the ideal case. The relative errors of Stokes vector caused by the imperfection of colorPol polarizer and the uncertainty due to the polarizer assembly in the telescope are estimated to be about 5%. Among the considered parameters, we find that the dominant error comes from the uncertainty in the maximum transmittance of the polarizer. | Li Feng Hui Li Bernd Inhester Bo Chen Bei-Li Ying Lei Lu Weiqun Gan | 2019 | Research in Astronomy and Astrophysics2019，19，4： | 2 |
| 13 | Space Solar Physics in China显示文摘The activities of Chinese space solar physics in 2018–2020 are going on smoothly.Besides the missions of ASO-S and CHASE which are in the engineering phases,there are quite a number of projects which are in the pre-study stage(conception study)or have finished the pre-study stage,constituting a rich pond for the selection of next solar mission(s).This paper describes in brief the status of all these related projects. | GAN Weiqun | 2020 | 空间科学学报2020，40，5： | 1 |

| 15 | A good example of high-energy radiation delay event显示文摘THE delay of high-energy radiation of solar flares can be divided into two types: one is the energy-dependent delay in the hard X-ray regime, the other is the delay between the hard X-rays and instantaneous γ-ray line (GRL) emissions. Both types have different physical meanings. The former reflects the difference in acceleration or transportation of energetic electrons with various energies, while the latter reflects such a difference between the energetic electrons | GAN Weiqun and Rieger Erich1 Purple Mountain Observatory, Nanjing 210008, China 2.
