本文证明了子群都是有限逼近的正则半群是有限逼近的，并且证明了每个主因子的幂等集合是有限的。作为一个推论，得到了某类正则半群有限逼近的充分必要条件。
In this note it is proved that a regular semigroup whose subgroups are all finitely approximable is finitely approximable and that the set of idempotents of each principal factor is finite. As a corollary necessary and sufficient conditions are found for certain classes of regular semigroups to be finitely approximable.
