英文摘要：

Taking two membrane oscillators in the optical cavity as an example, This paper in- troduces the basic principle and numerical method of the calculations for the coupling relations between the membrane oscillators and the electromagnetic field in optical cavity. Making use of this method, we can work out the coupling relations between the membrane oscillators and the electromagnetic field at any position in the cavity.
