demivolt

demivolt 的音标是["di:mɪvɔlt]，基本翻译是电位差或电压差。速记技巧可以考虑将音标中的元音音素进行简化处理，如可以将/i/和/əu/简化记作“一”和“沃”，这样可以将demivolt简记为“地一沃夫特”。这样的速记方法可以帮助记忆单词的发音和拼写。

Demivolt，意为“半电压”，其英文词源为“demi”和“volt”，分别表示“半”和“伏特”，是一种电力单位。

变化形式：复数形式为demivolts，过去式为decreased volt，现在分词为demivolting。

相关单词：

voltmeter：伏特计，用来测量电压的仪器。

electrometer：电动计，一种测量电势差的仪器，与伏特计相反，用于测量负电压。

half-voltage：半电压，指的是电路中一半的电压。

mid-voltage：中电压，指的是电路中中间部分的电压。

subvolt：毫伏，电压单位，等于千分之一伏特。

supervolt：超伏特，电压单位，大于1伏特。

double-volt：双伏特，一种特殊的电压单位，用于描述交流电的频率。

voltampere：伏安，一种功率单位，等于一个电压单位和电流单位的乘积。

volt-ampere-hour：伏安时，一种能量单位，等于一个功率单位和时间的乘积。

以上单词都与demivolt有着密切的联系，并且可以用来描述不同电压和功率的相关概念。

英文小作文：

Voltage is a crucial factor in the operation of electrical equipment, and maintaining a stable voltage source is essential for ensuring proper function. From batteries to power grids, voltage plays a vital role in our daily lives. However, voltage can also be a source of concern when it drops or fluctuates, which can lead to equipment malfunction or reduced efficiency. To address this issue, we turn to the concept of demivoltage, which refers to the partial or intermediate voltage level between full voltage and zero voltage. In practical terms, demivoltage refers to the state of a device or system that is operating at a reduced voltage but still functional and efficient enough to meet our needs. For example, a battery that has partially discharged but still has enough power to operate an electronic device falls under the category of demivoltage. Understanding demivoltage and how it affects our daily lives can help us better maintain and use electrical equipment, ensuring that it operates at its optimal performance level.
