摘　　要：本文综述了物理学中对时间的认识,时间在不同的时空观下展现出不同的性质,在牛顿时空观中时间具有同时性和时间间隔不变性,而在相对论中时间是相对的,空间也是相对的,但时空作为一个整体是绝对的,即时空被其中的物质的能量动量张量所弯曲。然而随着量子力学的建立和完善,量子隧穿时间的认识却出现了分歧,本文着重介绍了弯曲时空中量子隧穿过程中的时间,表明相对论中的量子隧穿是一个瞬时过程的同时性。In this paper, the understanding of the time in Physics are reviewed, it＇s that the time shows different properties under the different concept of space-time. In Newton＇s time-space view, the property of the time is simultaneity and time interval invariance. In the theory of relativity view, the time and space arc relative, but the time-space is absolute, even if it＇s curved by the energy-momentum tensor of matter in the time-space. However, with the establishment and perfection of the quantum mechanics, people have different views about the quantum barrier penetration time. In this work, the quantum barrier penetration time in a curved space time is discussed. It shows that the quantum tunneling in the theory of relativity should be an instantaneous process.
