Recent article Revisiting the 2PN Pericenter Precession in View of Possible Future Measurements published by Iorio (Universe 6(4):53, 2020. https://doi.org/10.3390/universe6040053) argues that calculations of the secular 2PN precession of the orbital pericenter of a binary system accomplished by Damour and Schäfer (Nuovo Cim B Ser 101B(2):127–176, 1988. https://doi.org/10.1007/BF02828697) and Kopeikin and Potapov (Astron Rep 38(1):104–114, 1994) with different mathematical techniques are inconsistent, differ from each other and do not agree with the result obtained by L. Iorio. The purpose of this communication is to demonstrate that the article by Iorio (2020) is erroneous, suffers from misconceptions and cannot be trusted.

Iorio（Universe 6（4）：53，2020. https://doi.org/10.3390/universe6040053）发表的最近一篇文章，《关于可能的未来测量方法重新审视2PN中心点进动》的论点是，轨道的长期2PN进动的计算由Damour和Schäfer（Nuovo Cim B Ser 101B（2）：127–176，1988.https：//doi.org/10.1007/BF02828697）以及Kopeikin和Potapov（Astron Rep 38（1）:)完成的二元系统的中心（第104-114页，1994年），使用不同的数学方法是不一致的，彼此不同，并且与L. Iorio的结果不一致。此次交流的目的是证明Iorio（2020）的文章是错误的，遭受误解并且不能被信任。
