Pulse, throb, and pulsate mean to beat rhythmically, but differ. Pulse is neutral, like a steady rhythm in blood or machinery. Throb suggests painful beating, like a hurt head. Pulsate describes rhythmic glowing, like light or music. Not compared: pulse's 'heartbeat' and throb's 'pain' senses.

这三个词都表示有节奏地、强烈地跳动或搏动，但语气和常见搭配不同：pulse 中性客观，常用于医学或技术场景；throb 强调因疼痛或强烈情绪而产生的跳动感，带有不适或紧张的意味；pulsate 常描述灯光、声音或氛围有节奏地起伏、闪动，较少用于身体感觉。这里不比较 pulse 作名词表示“脉搏”的用法，也不比较 throb 作名词表示“阵痛、悸动”的用法。
