The development direction of contemporary philosophical thought and theory are the practical application. In the future, practical application is the existing form of philosophy, its research and link level will directly affect the status and role of philosophy in the information age. In the first half of this article, as to the objective trend of philosophy theory's development, from the problems of philosophy's practical application, analyzes and discusses the main issues that need to be solved in the area of philosophy's practical application, thinking and summarizes practical coping strategies . Theoretical Physics is an extremely important branch of science. With the increasing requirements of physical measurement precision and calculation accuracy, we must consider the impact of time on the physical quantities. In the latter half of this article, by the method of the theoretical analysis, introduces the basic concepts that dimension (including time, space and other dimensions) impact on the calculation of physical measurements and mathematical calculations, derived formulas of the impact. Through theoretical analysis, prove the relative accuracy of these formulas; completely meet the urgent requirement of modern physical theory calculations.
