根据GR稳定场的Kerr度规,由引力场质点重力加速度的逆变分量推导Kerr场质点的重力加速度逆变分量的球坐标精确表示式.结果表明,Kerr场中质点的重力加速度不仅与场源的质量、单位质量的角动量及质点在场中的位置有关,而且与质点的速度有关,这正是GR效应在Kerr场中质点运动的反映.%According to the Kerr metric of the GR stability field,the accurate expressions for the gravitational acceleration of a test particle in the Kerr field are derived and the expressions in special cases are discussed. The results show that Kerr field particle acceleration due to gravity is related to the quality of the field source > the angular momentum of unit mass and particle position, and the speed of the particle, which reflects the GR effect on particle motion in the Kerr field.
