OCl characteristics obtained by star counts are analyzed. Dynamical parameters of observed clusters are compared with the results of numerical experiments on modeling of nonstationary, nonisolated OCl. Possible causes and character of evolution for star clusters are considered. The external gravitational field of the Galaxy or effects of small age of the clusters may cause visible nonstationarity in the regular field for 27-31 percent of the observed clusters. The presence of massive clouds of dust and gas in the clusters' neighborhood increases this fraction to 90-100 percent.
