AbstractA method of 'multi-cloud model' (MCM) is proposed in this paper in order to research asymmetric profiles of spectral line formed by solar discrete active objects aligned along the line-of-sight direction. Based on the MCM method, under the conditions of certain assumptions and approximations, the line-of-sight velocity V and three other physical parameter approximation values, (i.e. Doppler width Delta lambda(D), source function S and optical depth at line center tau(O)) within different 'clouds' may be derived simultaneously by fitting both profiles theoretical and observational. An application example of the method with m = 3 shows that MCM method is suitable to measure the velocity fields of multi-object at the same time from their non-Gaussian profiles of complex. The V and Delta lambda(D) derived from the method are reliable, S and tau(O) are approximation. An influence of the variations of initial values in the parameter on the solution is given as well.
