We find that our postulation on weak CP Phase gives strict constraints on angle gamma in unitarity triangle DB and the element Vtd in Cabibbo-Kobayashi-Maskawa (CKM) matrix. The predicted Vtd is about 0.0086 and gamma about 75.3^o with the very narrow window respectively. These two parameters can be used to test our postulation precisely in near future.5 pages, Latex fileHigh Energy Physics - Phenomenologytext
