用法要点

句型搭配

systole 通常作为名词使用,描述心脏收缩的生理过程,常见于医学或生物学语境中,常与表示时间、测量或功能的词搭配。

• during systole
• the duration of systole
• systole and diastole

介词用法

systole 常与介词 "during" 连用,表示在收缩期间发生的事件;也可与 "of" 搭配,说明收缩的属性或测量。

• blood pressure rises during systole
• the force of systole
• measurements of systole

语域说明

systole 是专业医学术语,主要用于医学、生理学、健康科学等正式或学术场景,日常对话中较少使用,普通交流时可用 "heart contraction" 替代。

• in medical textbooks
• clinical reports on systole
• research about cardiac systole

基础例句

The doctor explained that systole is when the heart contracts to pump blood.

医生解释说,心脏收缩期是心脏收缩以泵出血液的时候。

During exercise, my systole feels stronger and faster.

运动时,我感觉心脏收缩更加强烈和快速。

She learned in biology class that systole is part of the heartbeat cycle.

她在生物课上学到,心脏收缩期是心跳周期的一部分。

If systole is too short, it might affect blood flow.

如果心脏收缩期太短,可能会影响血液流动。

高级例句

The research paper analyzes how hypertension impacts ventricular systole duration in elderly patients.

这篇研究论文分析了高血压如何影响老年患者的心室收缩期持续时间。

In clinical trials, we monitor systole to assess cardiac function after medication.

在临床试验中,我们监测心脏收缩期以评估药物治疗后的心脏功能。

The medical device measures systole pressure accurately for diagnostic purposes.

这种医疗设备能精确测量收缩期血压,用于诊断目的。

常见错误

❌ 错误:The systole is pumping blood.
✓ 正确:Systole is the phase when the heart pumps blood.

错误用法将 systole 误用作动词或主动过程。systole 是名词,指心脏收缩的时期或状态,应描述为阶段或事件,而非动作本身。

❌ 错误:I feel systole in my chest.
✓ 正确:I feel my heart contracting during systole.

错误用法直接说“感觉到 systole”,这不够自然。systole 是专业术语,日常表达中应使用更通用的词汇如“心脏收缩”来描述感觉,以符合母语习惯。

近义词辨析

contraction

contraction 是更通用的词,指任何肌肉或器官的收缩,包括心脏;systole 特指心脏收缩期,更具专业性,常用于医学语境。

Muscle contraction can be voluntary, but cardiac systole is involuntary and rhythmic.

heartbeat

heartbeat 指完整的心跳周期,包括收缩和舒张;systole 仅指收缩部分,是 heartbeat 的一个阶段,更具体。

A normal heartbeat consists of systole and diastole, with systole being the active pumping phase.
