摘　　要：Landau在他的《场论》中导出了纯引力场的能量-动量表示tik,但没有给出表示tik的具体推导.沿袭Landau推求纯引力场能量-动量表示的思路,从Einstein场方程出发,根据等效原理具体而严格地推导了纯引力场的能量-动量赝张量表示,其结果能很好地与Landau所给出的tik表示一致.In his book The Classical Theory of Fields, Landau gave the expression of energy-momentum pseudotensor of the gravitational field （t^ik） ; however, he failed to present the concrete deductive process of t^ik. In accordance with Landau＇s thinking, on the basis of the principle of equivalence, from the gravitational field equation, we have rigorously reconsidered the concrete deductive process of the expression of energy-momentum pseudotensor of the pure gravitational field and the result is in good agreement with t^ik given by Landau.
