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。
I twist my neck, trying to catch her expression, but I can see only half of it: flutter of eye, curve of lip, and slice of cheek.
我扭转脖子，想看看她的表情，可也只能看到一半儿：眼睛的煽动、嘴唇的弧度，面颊的一片儿。
Methods the 5 cases with enhanced CT images were measured at each slice, then the Hu of aim position was obtained and the Hu time curve was got. At last, the valid enhanced period would be found.
方法对5例肝门动态扫描ct增强图像有关靶部位的CT值逐层测量，从而得到相应的“CT值时间曲线”，最终找出有效增强周期。
