摘要：
Structure of Bi(100-x)Ga(x)molten alloys containing 38 center dot 5, 50, 70 and 91 center dot 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.
