摘要：

We present a derivation of an exact, low-density equation of motion for the generating operator G((q) over bar)) = exp (i t) 1j >< i L For the case of foreign gas pressure broadening, the equation for G(ij)(t) may be used to obtain an exact rate equation for the line amplitude operator. Under certain well-defined approximations, this rate equation reduces to the form of an equation proposed by Gordon. The origin of the linear density term is considered. We discuss the implications of the use of only completed collisions to describe the spectrum.
