The warping associated with the closed timelike curve could cause our slice to twist back on itself, making it impossible to divide all of space-time into distinct moments.
与封闭的时间型曲线相关的这种扭曲会导致我们的切分转回原处，不可能把所有的时空分成各自不同的时刻。
This phenomenon, predicted by Einstein's theory of general relativity, causes light to curve as it flies through space-time that has been dented by the gravity of large bodies of mass.
这一现象是指光线在时空中传播的过程中由于大质量物质的引力而发生弯曲，这也是爱因斯坦的广义相对论所预言的。
Because light travels in a straight line through the contours of space-time, a light beam will curve where space-time curves, this curving was first measured in 1919.
因为光沿时空走直线，所以光线在时空弯曲的地方会弯曲。这现象在1919年首次被观测到。
Time history curve and space curve of the dynamical strain and bond stress of insert rebar with different anchorage length and loading conditions were gained.
给出了爆炸荷载作用下锚筋动应变及动粘结应力的时程分布曲线和空间分布曲线，研究了锚长、加载速率和加载方式等各种因素的影响。
A time optimal control method switched by time is put forward in the paper based on the concept of subspace of the initial state space. It doesn't need switching curve or switching surface.
基于初始状态空间下的子空间概念，提出一种按时间进行切换的最速控制方法，不需要求取开关线或开关面。
