The concept of projective matix over an unital C*-algebra was introduced and its property discussed.A sufficient and necessary condition to determine a 2-order matrix over a unital C*-algebra was proved.On this base,the projective completions problem for two partial matrices was studied,and sufficient and necessary conditions for two partial matrices having projective completions were obtained.
