您要查找的是不是:
- It is usually expressed as (Hz) Hertz or CPS (cycles per second). 一個完整周期為360度,相角就是用度數來表示兩個波的距離。
- The number of cycles per second is the frequency. 而頻率則是指每秒可完成的周期數。
- In the US most household current is AC at 60 cycles per second. 在美國,大部分家用電器使用赫茲的交流電。
- A unit of frequency equal to one cycle per second. 赫茲頻率的單位,等於每秒一周
- Frequency is measured in hertz, or cycles per second. 頻率用赫茲即每秒鐘的周數來計算。
- This radio signal has a frequency of 800000 cycles per second. 這個無線電訊號的頻率是每秒八百千周。
- Having a pitch corresponding to a relatively small number of sound-wave cycles per second. 低音的與一相對少量的每秒鐘音波周期相對應的低音的
- They typically center on a range of 1. 5 to 4 cycles per second. 頻率集中在每秒1.;5周至每秒4周之間。
- The frequency of modulation was 40 cycles per second. 調製頻率是每秒鐘40個周期。
- Analogue bandwidth is measured in Hertz (Hz), cycles per second. 類比式頻寬以赫茲測量每秒的傳送周期.
- Electricity in El Salvador is 115 Volts, alternating at 60 cycles per second. 薩爾瓦多電流的電壓是115伏特、60赫茲。
- The hertz (Hz), a unit of frequency in cycles per second, is named for him. 頻率單位hertz(Hz,等於每秒周數)即是以他的名字命名。
- In fact, many cortical cells are known to fire at rates between10 and40 cycles per second without external provocation. 事實上,許多皮質神經元在沒有外來刺激的情況下,每秒的放電頻率是10~0次。
- For low-frequency currents(up to about 15, 000 cycles per second)an iron core, called a magnetic circuit; is placed. 對於低頻率電流(約15,000周/秒以內),置有一個叫作磁路的鐵心。
- Electricity in Czech Republic is 230 Volts, alternating at 50 cycles per second. 捷克共和國電流的電壓是230伏特、50赫茲。
- Electricity in Papua New Guinea is 240 Volts, alternating at 50 cycles per second. 巴布亞紐幾內亞電流的電壓是240伏特、50赫茲。
- Although Tesla developed several two-wire motors, these so-called split-phase designs ran best on currents of 50 cycles per second or less. 雖然特士拉研發出好幾種雙線式馬達,但這些所謂的分相式設計最好是以50赫茲或更低頻率的電流推動。
- LIGO and the other ground-based detectors are sensitive to frequencies from a few tens of Hertz (cycles per second) to a few thousand Hertz. LIGO和其它的地基探測器對從幾十赫茲(每秒的周期數)到幾千赫茲的頻率都是敏感的。
- Humans in the prime of life can hear noises up to about 20,000 cycles per second. 人在壯年的時候可以聽到最高20000周秒赫的噪音。
- The speed of a computer is usually expressed in cycles per second. Typical machines operate at 100 to 200 megahertz or 100 million to 200 million cycles per second. 計算機的速度通常用每秒(執行)的(時鐘)周期來表示。典型的機器運轉在100到200兆赫或者說每秒100到200兆周期。
