Aiming at improving the survey efficiency of the Wide Field Survey Telescope, we have developed a basic scheduling strategy that takes into account the telescope characteristics, observing conditions, and weather conditions at the Lenghu site. The sky area is divided into rectangular regions, referred to as “tiles,” with a size of2°. 577 × 2°. 634 slightly smaller than the focal area of the mosaic CCDs. These tiles are continuously filled in annulars parallel to the equator. The brightness of the sky background, which varies with the moon phase and distance from the moon, plays a significant role in determining the accessible survey fields. Approximately 50connected tiles are grouped into one block for observation. To optimize the survey schedule, we perform simulations by taking into account the length of exposures, data readout, telescope slewing, and all relevant observing conditions. We utilize the Greedy Algorithm for scheduling optimization. Additionally, we propose a dedicated dithering pattern to cover the gaps between CCDs and the four corners of the mosaic CCD array, which are located outside of the 3° field of view. This dithering pattern helps to achieve relatively uniform exposure maps for the final survey outputs.

“新歌剧”问题贯穿了自清末戏曲改良到延安文艺民族形式探索的现代中国戏剧史,20世纪30年代,民众戏剧热潮更赋予其表现民众之声的核心诉求。然而,追求民众性、现代性、民族性相统一的新歌剧理想要面对诸多观念桎梏和实践难题,“咏叹”与“戏”因此成为一组被不断问题化的关键词。从早期的中西、新旧分途,到王泊生拼贴混搭的理论表述和剧本创作受到广泛抨击,再到“咏叹调民族化”与“板腔体咏叹化”实践的深化,“板腔体咏叹调”逐渐在延安文艺中形成。“咏叹”与“戏”从对立走向辩证综合的历程,以一个新视角打开了现代文艺大众化与民族化/中国化探索的历史纵深。
