摘要	The variations of the orbital periods of two Algol-type eclipsing binaries, T LMi and RW Mon, are presented through a detailed analysis of (O-C) diagrams. It is found that, apart from a secular decrease, several sudden jumps have occurred in the orbital periods of both binary systems: The period decrease rate was derived to be -1.12 x 10(-8) d/cycle and -1.456 x 10(-9) d/cycle for T LMi and RW Mon, respectively. Such a large rate is impossibly explained by angular momentum loss and mass loss due to magnetic stellar winds. The sudden jumps in the orbital periods of both stars might be caused by a rapid mass exchange between the circumstellar matter and binaries. At last, the evolutionary trend of the two Algol-type systems, whose periods decreased continuously, is discussed. Their evolutionary outcome might be W UMa stars.
