时间方向性

复杂性科学的兴起，指出时间具有方向性，是不可逆的。

But the complexity science points out that time has direction , and it is irreversible .

论时间的方向性

About the direction of time

从P波和S波提取的震源时间函数的方向性效应都清楚地表明：走向为199°的节面为断层面，地震是从东北向西南方向的单侧破裂。

The results are as follows : The directivity of source time functions retrieved from P-and S-waves indicate that the nodal plane striking 199 ° is the fault plane , and that the earthquake ruptured unilaterally from the northeast to the southwest .

通过把空间和空间中的物体映射到时间范畴，时间就获得了方向性、不可逆性、持续性和可测量性等特征。

Through the mapping of objects in the domain of space onto time , time acquires the features of directionality , irreversibility , continuity and measurement .

根据概念隐喻理论，可将时间概念隐喻分为三大类，即本体时间隐喻、结构性时间隐喻和方向性时间隐喻。

Time conceptual metaphors , according to conceptual metaphor theory , can be categorized into three groups : " ontological metaphors of time ", " structural metaphors of time " and " orientational metaphors of time " .
