1.Units: megahertz (MHz) AM (amplitude modulation), 200 and up are for military use, but are staffed by the same civil controllers.
单位：兆赫，调幅，200以上为军用，亦为民航管制员执勤。
2.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.
计算机的速度通常用每秒（执行）的（时钟）周期来表示。典型的机器运转在100到200兆赫或者说每秒100到200兆周期。
3.A personal computer with a 100-megahertz clock then executes 100 million stages per second.
一台时钟频率为100兆赫的个人电脑每秒能执行一亿次运算。
4.One 1995 microprocessor uses this deeper pipeline to achieve a 300-megahertz clock rate.
一台1995年生产的微处理器用这种更先进的流水线操作可达到300兆赫的时钟频率。
5.The speed of SDRAM, therefore, is not measured in the familiar old nanoseconds but in megahertz, like processors.
故而，SDRAM的速度不再用大家熟悉的纳秒来度量，而像处理器那样用兆赫（MHz）来度量。
6.When determining the speed of a computer, the number of megahertz branded onto the chip tells only one part of the story.
在确定一台计算机的速度时，标在芯片上的兆赫数只告诉了事情的一个方面。
7.In actual fact, a suitably modified amateur radio transmitter operating in either the 420 to 450 megahertz band or the 1.3 gigahertz band, with a highly directional antenna, is capable of transmitting voice to skull signals at less cost than the price of an automobile.
事实上,一个适当限制在420到450兆赫波段或1.3千兆赫波段的带有高度定向天线的业余无线电广播发射机,能够把声音信号传给头骨并且所花的费用比一辆汽车的价格还要少。
8.Hence, a 250- megahertz, four-way superscalar microprocessor can execute a billion instructions per second.
因此一台250兆赫、四线超标量体系结构的微处理器能在一秒钟内执行十亿条命令。
9.The bandwidth(megahertz) and spectrum position of the signal arising from television scanning.
电视扫描信号所占的频谱位置和带宽（以兆赫计）。
10.High-speed analog-to-digital conversion chips can thus exploit hundreds of megahertz of RF spectrum simultaneously.
高速类比数位转换晶片因此能同时运用数亿赫兹的RF频谱。
