wide amplitude range
解釋
大幅值范圍-
In voice transmission, to compress the signal amplitude into a narrow range be cause the amplifiers are linear over wide ranges
在話音通信中,因放大器的線性范圍有限,把信號幅度壓縮到一個較小范圍的處理。 -
The output voltage parameters such as amplitude, frequency and duty ratio can be variable in a wide range with programmable digital adjustment

Its growth temperature range is from 6 to 40 and optimum temperature range is about 24. when the temperature is reduces to 22 immediately ( from 35 to 13 ), it can still grow. after it is frozen at - 18, it still can restore to life, which is a feature that other spirulina do not have. compared with the introduced spirulias platensis, it shows low temperature characteristic and wide temperature ecological amplitude
其生長的溫度范圍是6 - 40 ;最適溫度為24左右;在溫度驟降幅度達22時(從35降到13 )依然能夠生長;該藻在- 18冰凍之後依然可以復生;其對低溫的適應特性是引進的鈍頂螺旋藻和極大螺旋藻所不具備的。 -
Digital sound broadcasting is a general term covering a wide range of systems and technologies, including eureka 147 and isdb - t, which are designed to replace frequency modulation broadcasting, digital radio mondiale, a possible successor to amplitude modulation, as well as iboc, which is intended to complement the existing am and fm services
數碼聲音廣播?是一個統稱,技術上是分為不同的系統和制式,有取代fm廣播的eureka 147和isdb - t ,也有針對am廣播的drm ,和可以與am fm並存的iboc等系統,它們都有一個共通點,是現時的收音機並不適用。 -

Underwater acoustic data acquisition equipment is necessary for underwater acoustic experimentation. since the situation underwater is very complicated, we must adopt the data acquisition equipment which is adaptive to the abominable field underwater. all of these make us to make the data acquisition equipment to has a wide dynamic range and have the utility to acquire the signals which have large amplitude range
水聲數據採集裝置對於水聲試驗來說是不可缺少的,由於水底的自然環境極其復雜,這就要求我們所採用的數據採集器能夠適應水下惡劣的自然環境,因此所採用的數據採集器應具有較大的動態范圍,所採集信號的幅度范圍要盡可能的寬。
