您要查找的是不是：
- pulse falling edge 脉冲下降边沿
- Otherwise, wide pulse and slow falling edge can cause the errors of surface recombination velocities and bulk lifetime extracted from the photoconductive decay curve. 否则脉冲光过长的脉宽和下降沿将对光电导衰减曲线中进一步分离出的表面复合速度和少子体寿命结果造成误差。
- If the host pulls clock low before the first high-to-low clock transition, or after the falling edge of the last clock pulse, the keyboard/mouse does not need to retransmit any data. 如果在第一个高->低时钟跳变时，（或者在最后一个时钟脉冲的下降沿之后）主机将时钟拉低，键盘/鼠标不必重新传输任何数据。
- If the host pulls clock low before the first high-to-low clock transition, or after the falling edge of the last clock pulse, the keyboard/ mouse does not need to retransmit any data. 如果在第一个高->时钟跳变时，（者在最后一个时钟脉冲的下降沿之后）机将时钟拉低，键盘/标不必重新传输任何数据。
- If the host pulls clock low before the first high-to-low clock transition, or after the falling edge of the a last clock pulse, the keyboard/mouse does not need to retransmit any data. 如果在第一个高->低时钟跳变时，（或者在最后一个时钟脉冲的下降沿之后）主机将时钟拉低，键盘/鼠标不必重新传输任何数据。
- We use a simple pulsewidth-recovering circuit des ign to avoid the range limitation caused by the difference propagation speeds of the rising edge and the falling edge of the circulation pulse. 使用一种简单的电路让循环脉冲每一周均回复其脉宽，使可转换的时间长度不会如以往装置因脉冲之前沿与后沿前进速度不同而受到限制。
- In case that the camshaft signal measured by the first falling edge after dentation is low, then the following TDC would be of the first cylinder. 若缺齿后第一个下降沿检测到凸轮信号为低，则接下来的TDC是一缸TDC。
- The superiority of the method is the pectinate filter characteristic, that is, the power ratio of the two output arms changes fast with the Bragg wavelength while in the rising or falling edge of the output spectrum. 该方法主要是基于 MZ 干涉仪的梳状滤波特性,即在输出光谱的上升或下降沿两输出臂的功率比值随波长变化很快,通过调整干涉仪臂长差,得到具有陡峭边沿的滤波器。
- Since DDR memory in the clock rising edge and falling edge of the transmission of data can, therefore, at the same clock frequency and data-bit width memory bandwidth cases are twice as common SDRAM. DDR显存因为能在时钟的上升沿和下降沿都能传送数据，因此，在相同的时钟频率和数据位宽度的情况下显存带宽是普通SDRAM的两倍。
- A falling board struck him edge on. 一块木板掉落时，侧边打在他身上。
- An unwanted false electronic pulse. 一种不希望有的假电子脉冲。
- He has a knack of falling out with everyone. 他有个怪癖，总是和每个人吵架。
- She was hit by a piece of falling masonry. 她被建筑物上落下的一块石头砸着了。
- He knew the pulse of the nation. 他了解国民的心态。
- The doctor took my temperature and my pulse. 医生量了量我的体温和脉搏。
- The first is DDR (Double Data Rate) signaling, which transfers data on both the rising and falling edges of the clock signal, doubling the data transmission rate, a technique commonly used in DRAMs. 第一项是的DDR （双倍数据速率）信令，数据传输上都上升和下降边缘的时钟信号，增加一倍，数据传输速率，技术，普遍使用的DRAM的。
- The excitement quickened my pulse. 激动使我的心跳加快。
- The captain upbraid his men for falling asleep. 上尉因他的部下睡着了而斥责他们。
- The machine is operated by an electronic pulse. 这台机器由电子脉冲信号操纵。
- Laid-off workers fall into penury. 下岗职工陷入贫困。
