Professor Venzo de Sabbata is a famous Italian physicist in the world. He is engaged with a series of creating research works about the general relativity theory applying to astrophysics, and achievies glorious successes. The author pays attention to his works in this field, especially his paper titled "Is it dark matter necessary to explain galaxy rotation curves?"In order to coincide with the astrophysical observations, Milgrom adopted a new foundamental acceleration a 0 to modify the Newtonian Dynamics (MOND).Meanwhile Sabbata explored another approach wisely by introducing the innate related torsion with intrinsic spin of the particle into the general relativity theory, and showed penetratively that without use of dark metter for explanation,the foundamental accelerations a max and a min will be derived from the quantum effect yielded by the torsion. They are the nice results which can be derived from an accurate solution of the related equations in the Einstein Cartan general relativity theory.
