Since GMt and therefore dMdt increases at t I and Vt decreases with time ASS1 increases over a small time interval if如何理解这句话

This sentence means that if the function G[M(t)] increases with time and the function V(t) decreases with time, then the variable ASS1 will also increase over a short period of time. This suggests that there is a relationship between the rate of change of M and the rate of change of V, which affects the value of ASS1.
