摘要翻译：
利用集体变量(CV)方法，重新考虑了多元非均质流体统计场理论的基本关系式。相应的CV作用依赖于两组标量场--与$\alpha$粒子的局域密度涨落有关的场$\rho{\alpha}$和与$\rho{\alpha}$共轭的场$\omega_{\alpha}$。给出了CV场相关的显式表达式及其与密度相关函数的关系。建立了微扰理论，并详细考虑了该理论的平均场能级(MF)。

英文摘要：
Using the collective variables (CV) method the basic relations of statistical field theory of a multicomponent non-homogeneous fluids are reconsidered. The corresponding CV action depends on two sets of scalar fields - fields $\rho_{\alpha}$ connected to the local density fluctuations of the $\alpha$th species of particles and fields $\omega_{\alpha}$ conjugated to $\rho_{\alpha}$. The explicit expressions for the CV field correlations and their relation to the density correlation functions are found. The perturbation theory is formulated and a mean field level (MF) of the theory is considered in detail.
