the pulsation of sth
The pulsation of the electrical signal indicates a fault.
电信号的脉动表示存在故障。
搏动；脉动；脉搏
一次搏动；一次跳动；一次振动；脉冲；瞬时脉冲；周期性波动；交替增减；节律性胀缩；心脏、动脉等在活体内的规律跳动；脉搏
The rhythmic beating or throbbing of the heart, arteries, or other body parts; the pulse.
心脏、动脉等在活体内的规律跳动；脉搏
The regular throbbing of the heart, an artery etc. in a living body; the pulse.
(电子学)正常电状态中的尖锐瞬变波(或一系列此类瞬变)
(electronics) a sharp transient wave in the normal electrical state (or a series of such transients)
任何有节奏的跳动、搏动等
Any rhythmic beating, throbbing etc.
周期性出现的现象,交替增加和减少某种数量
a periodically recurring phenomenon that alternately increases and decreases some quantity
裸露的游动孢子和变形体的节律性大小变化
The rhythmic increase and decrease of size in naked zoospores and plasmodia.
动脉随心跳的节律性收缩和扩张
the rhythmic contraction and expansion of the arteries with each beat of the heart
单次跳动、搏动或振动
A single beat, throb or vibration.
The engineer detected a faint pulsation in the circuit's voltage.
工程师检测到电路电压中微弱的脉动。
用法提示：此处pulsation作为名词，指电路电压中的短暂波动（电子学中的脉动）。
AI contextual example

AI contextual example
The pulsation of the electrical signal indicates a fault.
电信号的脉动表示存在故障。
We observed a pulsation in the voltage waveform.
我们观察到电压波形中有一个脉动。
Pulsations occur at regular intervals in the circuit.
电路中周期性出现脉动。
The sensor can detect pulsations in the magnetic field.

最直接的近义词，可与pulsation互换，指单个瞬变波。
强调瞬时冲击，常用于电路理论，与pulsation稍有区别。
更泛指短暂现象，不特指波形，替换时需注意上下文。
指尖锐峰值，比pulsation更具体，常用于噪声描述。
强调幅度增大，可能持续稍长，与pulsation的瞬变特性略有差异。

易错句子The machine pulsations every second.
正确表达The machine pulsates every second.
将名词“pulsation”误用作动词，应使用动词形式“pulsate”。

易错句子I felt a strong pulsation in my wrist.
正确表达I felt a strong pulse in my wrist.
“pulsation”通常指一连串的脉动或震动，而单个脉搏跳动应用“pulse”。
pulse (名词) 指单一的短暂波动或脉冲，而 pulsation (名词) 指一系列或持续的脉动现象。
puls + -ate
pulsat(e) + -ing
pulsat- + -ile
