每秒脉冲(PPS)指的是在一秒钟内的脉冲或脉冲拨号次数。
Pulses per second (PPS) refers to the number of pulses per second and the number of dial pulses per second.
脉冲星是已经死亡的小型中子星，直径只有20公里(12.4英里)左右，每秒旋转数百次，同时还会向外发出无线电光束。
Pulsars are tiny, dead neutron stars that are only around 20 kilometers (12.4 miles) in diameter and spin hundreds of times a second, emitting beam of radiation.
“我们在每根线缆的两端每秒加一个电脉冲”Petrenko说，“所有的冰就都脱落了。”
"We apply [an] electric pulse to either end of the cable for about one second," Petrenko says, "and all ice attached to it falls down."
小灵通使用TDMA(分时多址)/(时分复用)作为其接入无线网络的方法，且声讯编码以自适应差分脉冲编码调制方式调制，速率为每秒32千比特。
PHS uses TDMA/TDD for its radio channel access method, and 32 kbit/s ADPCM for its voice codec.
在森林探测过程中，载有激光雷达的飞机将每秒产生7万个脉冲的激光束向森林树冠进行扫掠。
During a forest survey, an aircraft-borne lidar sweeps a beam that fires about 70,000 pulses a second over the canopy.
在低频率(譬如每秒十次)时，所感觉到的是脉冲而非振动。
At low frequencies, such as 10 per SEC., pulsation is sensed rather than vibration.
例如，快速以太网链路送来的持续的长脉冲串可能冲垮每秒10万包处理能力的服务器。
A sustained burst from a Fast Ethernet link, for example, can blast a server with 100,000 packets per second.
千万年以来，地球的Schumann共振(Schumann Resonance)或脉冲(心跳)为每秒7.83周，军事上一直将其作为极其可靠的参考来使用。
For thousands of years the Schumann Resonance or pulse (heartbeat) of Earth has been 7.83 cycles per second, the military have used this as a very reliable reference.
同一个光纤环形激光器输出的由光纤光栅布喇格波长决定的两个不同波长的光脉冲可以每秒十万次的速度切换。
Output optical pulses from the laser can switch between two wavelengths determined by the Bragg wavelengths of two fiber gratings in the ring at the rate of 105 per second.
