The dynamics of accretion disk is considered taking into account the Lense–Thirring precession in the presence of cosmological constant \(\varLambda \) of Schwarzschild–de Sitter metric. The nodal and apsidal frequencies are obtained, and the role of \(\varLambda \) is revealed in their properties, including the consequences for the Bardeen–Petterson effect.

关于$ \ varLambda $$Λ在吸积磁盘上的作用

在存在Schwarzschild-de Sitter度量的宇宙学常数\（\ varLambda \）的情况下，考虑了Lense-Thirring进动的情况，考虑了吸积盘的动力学。获得了节点频率和两点频率，并且\（\ varLambda \）的作用在它们的属性中得到了揭示，包括对Bardeen–Petterson效应的影响。
