正确说法

• 患者的呼吸微弱而不规律，需要立即插管辅助通气。(The patient's breathing is faint and irregular — immediate intubation for assisted ventilation is required.)
• 即使信号再微弱，只要还有一格，卫星电话也能勉强接通。(Even with the faintest signal — just one bar — a satellite phone can still just about connect.)

错误说法

• 将微弱用于形容能力不足，如'他的能力微弱' — for human capability, use 薄弱 (weak/lacking) or 欠缺 (insufficient); 微弱 is for physical signals, sounds, vital signs, and forces

起源与历史

Compound of 微 (minute, faint) + 弱 (weak, feeble). Together they intensify the sense of barely-there fragility — something so faint it is on the verge of vanishing.
