- pulse propagation time 脉冲传播时间
- Summing up time harmonic propagated waves of all frequency gives the pulse propagation along the line. 加总所有频率成份弦波之时域传播即得时域脉波之传播。
- Nondestructive pressure measurement based on surface wave usually requests accurate measurement of propagation time of surface wave in the medium. 基于表面波的压力无损测量方法要求精确地测量表面波在介质中的传播时间。
- For long-baseline asynchronous positioning systems based on measure of time-delay, range ambiguities appear when pulse's propagating time is longer than its repetition period. 对于基于时延测量的长基线异步定位系统,当信号传播时延大于脉冲重复周期时,就会出现距离模糊。

- Increasing the driving field intensity, the medium"s dispersion changes from normal to anomalous, which leads to the switching from subluminal to superluminal light pulse propagation. 通过增加驱动场的强度,光学介质的色散性质由正常色散向反常色散转换,导致光的传播速度由慢光速到超光速的转换。
- Electromagnetic pulse propagation 电磁脉冲传播
- Applies default root permissions to the OS partition and propagates them to unprotected children. Propagation time depends on the number of unprotected children. 将默认根权限应用于OS磁盘分区并传播到未受保护的子分区。传播时间由未受保护的子分区数决定。

- high-level to low-level propagation time 高电平到低电平传输时间
- phase propagation time difference 相位传播时间差
- When such a powerful laser pulse propagates through the plasma, it becomes both shorter and narrower, creating a large electron bubble that traps electrons from the plasma. 当如此强大的雷射脉冲传递到电浆的时候,脉冲会变得更短更窄,创造出一个很大的电子泡泡,而可以从电浆中抓住电子。
- Fruit juices ferment if they are kept a long time. 果汁若是放置很久,就会发酵。
- Time is sometimes called the fourth dimension. 时间有时被称为第四度空间。
