The three-fluid model equations for the solar wind are solved simultaneously in a self-consistent manner. The model consists of the individual continuity, momentum, and energy equations for electrons, protons, and alpha-particles without considering the alpha-particle as a minor species. The importance and the meaning of the 'critical points' are discussed along with the proper manner of choosing them. A possible explanation for the observed streaming velocities of the alpha-particles being larger than the proton streaming velocities is given. A weak correlation was found between the ratios of the alpha-to-proton velocities and their temperatures near 1 AU. A definite anticorrelation between the relative alpha-particle abundance and the particle flux was found to be in agreement with observation and in contradiction to previous theoretical models.
