The NASA Kepler mission obtained long-term high-quality photometric observations for a large number of stars in its original field of view from 2009 to 2013. To provide reliable stellar parameters in a homogeneous way, the LAMOST telescope began to carry out low-resolution spectroscopic observations for as many stars as possible in the Kepler field in 2012. By June 2018, 238 386 low-resolution spectra with SNR _g ≥ 6 had been collected for 155 623 stars in the Kepler field, enabling the determination of atmospheric parameters and radial velocities, as well as spectral classification of the target stars. This information has been used by astronomers to carry out research in various fields, including stellar pulsations and asteroseismology, exoplanets, stellar magnetic activity and flares, peculiar stars and the Milky Way, binary stars, etc. We summarize the research progress in these fields where the usage of data from the LAMOST-Kepler (LK) project has played a role. In addition, time-domain medium-resolution spectroscopic observations have been carried out for about 12 000 stars in four central plates of the Kepler field since 2018. The currently available results show that the LAMOST-Kepler medium resolution (LK-MRS) observations provide qualified data suitable for research in additional science projects including binaries, high-amplitude pulsating stars, etc. As LAMOST is continuing to collect both low- and medium-resolution spectra of stars in the Kepler field, we expect more data to be released continuously and new scientific results to appear based on the LK project data.

NASA开普勒任务在 2009 年至 2013 年期间，在其原始视野中获得了大量恒星的长期高质量光度观测。为了以均匀的方式提供可靠的恒星参数，LAMOST 望远镜开始进行低分辨率2012 年在开普勒场中对尽可能多的恒星进行光谱观测。截至 2018 年 6 月，已在开普勒中为 155 623 颗恒星收集了238 386 个信噪比_g ≥ 6的低分辨率光谱 场，能够确定大气参数和径向速度，以及目标恒星的光谱分类。这些信息已被天文学家用于各个领域的研究，包括恒星脉动和星震学、系外行星、恒星磁活动和耀斑、奇特恒星和银河系、双星等。我们总结了这些领域的研究进展，其中来自 LAMOST- Kepler (LK) 项目的数据的使用发挥了作用。此外，自 2018 年以来，已经对开普勒场的四个中心板块的约 12000 颗恒星进行了时域中分辨率光谱观测。目前可获得的结果表明，LAMOST-开普勒中分辨率 (LK-MRS) 观测提供了适用于其他科学项目研究的合格数据，包括双星、高振幅脉动恒星等。随着 LAMOST 继续在开普勒场中收集低分辨率和中分辨率恒星光谱，我们预计在力劲项目数据的基础上，还会有更多的数据不断发布，新的科学成果会出现。
