摘要	It is found that the mass loss rate derived from S-25/S-12 is generally greater;than that from the OH flux. This suggests an increasing loss rate with time. It is found that the gas-to-dust ratio decreases during the evolution Of OH/IR stars. An empirical relation between the gas-to-dust ratio and the dust mass loss rate is derived, leading to a formula for calculating the total mass loss rate directly from the IRAS 60 mum flux. OH/IR stars with silicate emission have a larger range of mass loss ratio, from 10(-7) to 10(-5) M-circle dot/yr; those with silicate absorption, a smaller range between 10(-5) and 10(-4) M-circle dot/yr. So a large increase in the mass loss rate takes place during the emission phase.
