The field equation of gravitomagnetic matter is suggested and a static spherically symmetric solution of this equation is offered. With foreseeable improvements in detecting and measuring technology, it is possible for us to investigate quantum mechanics in weak-gravitational fields. The potential implications of these gravitational effects (or phenomena) to some problems are briefly discussed.6 pages, LatexGeneral Relativity and Quantum Cosmologytext
