1、The forging processes of the both kinds of billets were simulated by contrast with FEM and the distributions of their velocity, strain and fibre flown line were gotten.───有限元方法,对圆柱形和锥台形两种坯料的成形过程进行对比模拟,进一步得到了它们在成形过程中速度场、应变场和金属纤维流线的分布规律。
2、Portal velocity and portal flow with phase contrast (PC) were measured.───相位对比法(PC)测门静脉血流速度、每分钟流量。
3、Contrast, spatial frequency, presentation time, moving velocity and phase reversal frequency of each grating are controlled independently.───每组光栅的对比度、空间频率、显示时间,移动速度和反相频率能单独控制。
