为了利用伽马射线暴(GRB)的天体物理潜力，中国和法国的天体物理学家参与了SVOM任务(天基多波段天文可变物体监视器)。由于空间和地面观测之间的协同作用，空间和空间飞行器飞行任务在伽玛暴研究方面取得了重大进展，它实施了空间和地面仪器。这次飞行任务的科学目标特别强调了两类伽玛暴：位于z$和gt的非常远的伽玛暴；5美元的伽玛暴，它们构成了特殊的宇宙探测器；以及附近微弱/柔软的伽玛暴，它可以探测前体的性质和爆炸中起作用的物理现象。这些目标对任务的设计产生了重大影响：机载硬X射线成像仪的灵敏度低至4keV，并在线计算图像和速率触发，地面上的后续望远镜在近红外中具有灵敏度。在下一个十年开始时，SVOM将成为极短时间尺度上伽玛射线暴位置和光谱参数的主要提供者。SVOM仪器将与一系列强大的天文设备同时运行。这种罕见的工具性连接，再加上与GRB研究相关的科学主题的相关性，值得为SVOM带来显著的科学回报。此外，SVOM仪器主要是为伽玛暴研究设计的，它构成了一个独特的多波长天文台，具有快速回转能力，将在与伽玛暴相关的特定目标之外为整个天文学找到多种应用。这份报告列出了将从使用SVOM进行的观测中受益的科学主题，无论它们是特定的GRB主题，还是更笼统地说，可以利用SVOM的多波长功能的所有问题。

To take advantage of the astrophysical potential of Gamma-Ray Bursts (GRBs), Chinese and French astrophysicists have engaged the SVOM mission (Space-based multi-band astronomical Variable Objects Monitor). Major advances in GRB studies resulting from the synergy between space and ground observations, the SVOM mission implements space and ground instrumentation. The scientific objectives of the mission put a special emphasis on two categories of GRBs: very distant GRBs at z$>$5 which constitute exceptional cosmological probes, and faint/soft nearby GRBs which allow probing the nature of the progenitors and the physics at work in the explosion. These goals have a major impact on the design of the mission: the on-board hard X-ray imager is sensitive down to 4 keV and computes on line image and rate triggers, and the follow-up telescopes on the ground are sensitive in the NIR. At the beginning of the next decade, SVOM will be the main provider of GRB positions and spectral parameters on very short time scale. The SVOM instruments will operate simultaneously with a wide range of powerful astronomical devices. This rare instrumental conjunction, combined with the relevance of the scientific topics connected with GRB studies, warrants a remarkable scientific return for SVOM. In addition, the SVOM instrumentation, primarily designed for GRB studies, composes a unique multi-wavelength observatory with rapid slew capability that will find multiple applications for the whole astronomy community beyond the specific objectives linked to GRBs. This report lists the scientific themes that will benefit from observations made with SVOM, whether they are specific GRB topics, or more generally all the issues that can take advantage of the multi-wavelength capabilities of SVOM.
