- A unit of frequency equal to one cycle per second. 赫兹频率的单位,等于每秒一周
- The number of cycles per second is the frequency. 而频率则是指每秒可完成的周期数。
- Most British power stations generate A. C.(alternating current) with a frequency of 50 cycle per second,written 50 c/s far short. 大多数英国发电站都生产每秒兜周的交流电,简写为50cs。
- Most British power stations generate A. C.(alternating current) with a frequency of 50 cycle per second, written 50 c/s far short. 大多数英国发电站都生产每秒兜周的交流电,简写为50cs。
- In the US most household current is AC at 60 cycles per second. 在美国,大部分家用电器使用赫兹的交流电。
- Frequency is measured in hertz, or cycles per second. 频率用赫兹即每秒钟的周数来计算。
- The frequency is the number of waves that reach the shore each second, measured in hertz (Hz). 1 Hz is equal to 1 wave per second, or 1 cycle per second. 频率则是指每一秒波到达这个岸的数目,以赫兹(Hz)量测。1Hz等于每秒1个波,或每秒1个循环。
- This radio signal has a frequency of 800000 cycles per second. 这个无线电讯号的频率是每秒八百千周。
- Having a pitch corresponding to a relatively small number of sound-wave cycles per second. 低音的与一相对少量的每秒钟音波周期相对应的低音的
- They typically center on a range of 1. 5 to 4 cycles per second. 频率集中在每秒1.;5周至每秒4周之间。
- The frequency of modulation was 40 cycles per second. 调制频率是每秒钟40个周期。
- Analogue bandwidth is measured in Hertz (Hz), cycles per second. 类比式频宽以赫兹测量每秒的传送周期.
- It is usually expressed as (Hz) Hertz or CPS (cycles per second). 一个完整周期为360度,相角就是用度数来表示两个波的距离。
- Cycle determines the unit of frequency, such as cycles per second, Hertz, Hz, or cycles/second. 周期 确定单位的频率,如赫兹,赫兹的频率,或周期/秒。
- Electricity in El Salvador is 115 Volts, alternating at 60 cycles per second. 萨尔瓦多电流的电压是115伏特、60赫兹。
- The hertz (Hz), a unit of frequency in cycles per second, is named for him. 频率单位hertz(Hz,等于每秒周数)即是以他的名字命名。
- An internal clock in the CPU sets the speed of the machine cycle,which is measured in MHz-megahertz,er millions of cycles per second. 主机内部的时钟设定了机器周期的速度,这是以兆赫,或者几百万个周期/秒来计算的。
- In fact, many cortical cells are known to fire at rates between10 and40 cycles per second without external provocation. 事实上,许多皮质神经元在没有外来刺激的情况下,每秒的放电频率是10~0次。
- For low-frequency currents(up to about 15, 000 cycles per second)an iron core, called a magnetic circuit; is placed. 对于低频率电流(约15,000周/秒以内),置有一个叫作磁路的铁心。
