Two Li-rich candidates, TYC 1338–1410–1 and TYC 2825–596–1, were observed by the new high-resolution echelle spectrograph, LAMOST/HRS. Based on their high-resolution and high-signal-to-noise ratio (SNR) spectra, we derived stellar parameters and abundances of 14 important elements for the two candidates. The stellar parameters and lithium abundances indicate that they are Li-rich K-type giants, and having A(Li)_NLTE of 1.77 and 2.91 dex, respectively. Our analysis suggests that TYC 1338–1410–1 is probably a red giant branch (RGB) star at the bump stage, while TYC 2825–596–1 is most likely to be a core helium-burning red clump (RC) star. The line profiles of both spectra indicate that the two Li-rich giants are slow rotators and do not show infrared (IR) excess. We conclude that engulfment is not the lithium enrichment mechanism for either star. The enriched lithium of TYC 1338–1410–1 could be created via the Cameron-Fowler mechanism, while the lithium excess in TYC 2825–596–1 could be associated with either non-canonical mixing processes or He-flash.

新的高分辨率中阶梯光栅光谱仪 LAMOST/HRS 观察到两个富含锂的候选物，TYC 1338-1410-1 和 TYC 2825-596-1。基于它们的高分辨率和高信噪比 (SNR) 光谱，我们为这两个候选者推导出了 14 种重要元素的恒星参数和丰度。恒星参数和锂丰度表明它们是富锂 K 型巨星，具有 A(Li) _NLTE分别为 1.77 和 2.91 dex。我们的分析表明，TYC 1338-1410-1 可能是一颗处于凸点阶段的红巨星分支（RGB）星，而 TYC 2825-596-1 最有可能是一颗核心氦燃烧红团（RC）星。两个光谱的线轮廓表明，这两个富锂巨星是慢速旋转体，并且没有显示出红外 (IR) 过量。我们得出结论，吞噬不是两颗恒星的锂富集机制。TYC 1338-1410-1 的富锂可以通过 Cameron-Fowler 机制产生，而 TYC 2825-596-1 中的锂过量可能与非规范混合过程或氦闪有关。
