摘　　要：在Vaidya时空中,用滞后爱丁顿坐标形式,采用乌龟坐标变换,通过讨论哈密顿—亚可比方程,研究此黑洞非热辐射特征.结果表明,用滞后的爱丁顿坐标研究Vaidya黑洞的非热辐射与用超前爱丁顿坐标研究Vaidya黑洞的非热辐射得出的结论完全一致.In Vaidya spacetime, the quantum nonthermal radiation of black hole was studied through studying HamiltonJacobi equation by using Lagging Eddington coordinate and tortoise coordinate transformation, which shows the study of the Lagging Eddington coordinate and that of the leading Eddington coordinate have the same result.
