【 摘 要 】

Structure of Bi_{100−���?}Ga_�? molten alloys containing 38.5, 50, 70 and 91.5 at.% Ga has been studied by means of X-ray diffraction method and compared with viscosity measurements data. Significant changes in the structure factor profile were observed in vicinity of the concentration 70 at.% Ga. The dynamic viscosity coefficient was calculated by use of a statistical atomic distribution model and a Born�?�Green kinetic theory. The concentration dependence of viscosity is in agreement with change of structure parameters obtained from diffraction data.
