gigahertz(GHz)是频率单位,表示每秒十亿次周期,常用于描述计算机处理器、无线电波等的运行速度。

用法要点

句型搭配

gigahertz通常作为名词使用,在句子中作主语或宾语,常与数字连用表示具体频率值,如“3.5 GHz”。

• The processor runs at 2.4 gigahertz.
• This radio operates in the 5 gigahertz band.

介词用法

gigahertz常与介词“at”连用表示运行频率,如“at 3.0 GHz”;与“in”连用表示频率范围,如“in the 2.4 gigahertz range”。

• The CPU operates at 3.5 gigahertz.
• Wi-Fi signals transmit in the 5 gigahertz spectrum.

语域说明

gigahertz是技术术语,主要用于计算机、电子工程、通信等专业领域,在口语中常简写为“GHz”,日常对话中较少使用。

• This router supports dual-band: 2.4 GHz and 5 GHz.
• The new smartphone has a 3.0 GHz processor.

基础例句

My laptop's processor runs at 2.5 gigahertz, which is fast enough for everyday tasks.

我的笔记本电脑处理器运行在2.5千兆赫,这速度足够处理日常任务了。

This Wi-Fi router uses the 5 gigahertz band for less interference and faster connections.

这款Wi-Fi路由器使用5千兆赫频段,干扰更少,连接速度更快。

I heard the new gaming console has a CPU clocked at 3.8 gigahertz for smooth gameplay.

我听说新款游戏机的CPU主频达到3.8千兆赫,能保证游戏运行流畅。

高级例句

The research paper discusses semiconductor designs operating at terahertz frequencies, significantly beyond current gigahertz standards.

这篇研究论文讨论了运行在太赫兹频率的半导体设计,远超当前的千兆赫标准。

In telecommunications, the 28 gigahertz band is allocated for 5G networks to enable high-speed data transmission.

在电信领域,28千兆赫频段被分配给5G网络,以实现高速数据传输。

The processor's architecture allows it to dynamically adjust its clock speed from 1.0 to 4.0 gigahertz based on workload demands.

该处理器的架构使其能根据工作负载需求,动态调整时钟速度,从1.0到4.0千兆赫不等。

常见错误

❌ 错误:The computer has a speed of 3.5 gigahertzs.
✓ 正确:The computer has a speed of 3.5 gigahertz.

错误:gigahertz是单复数同形的名词,不应加“s”。正确用法直接使用“gigahertz”,如“3.5 gigahertz”。

❌ 错误:This device works on 2.4 gigahertz.
✓ 正确:This device operates at 2.4 gigahertz.

错误:在描述频率时,通常用“operate at”或“run at”,而不是“work on”。正确搭配是“at gigahertz”表示运行频率。

近义词辨析

megahertz

megahertz(MHz)是百万赫兹,频率低于gigahertz(GHz,十亿赫兹);1 GHz = 1000 MHz。gigahertz用于更高频率场景,如现代处理器,而megahertz常见于旧设备或低频应用。

Old computers often had processors in the hundreds of megahertz, while new ones exceed 3 gigahertz.

hertz

hertz(Hz)是基本频率单位,表示每秒一次周期;gigahertz是十亿赫兹。hertz用于通用或低频测量,gigahertz专指高频,如无线电波或CPU速度,更具体和专业。

Human hearing ranges from 20 hertz to 20,000 hertz, but Wi-Fi uses frequencies in the gigahertz range.
