用法要点

句型搭配

phlogiston 通常作为名词使用,在句子中作主语或宾语,常用于描述历史科学理论或化学概念。

• The theory of phlogiston was widely accepted.
• Scientists debated the existence of phlogiston.

介词用法

phlogiston 常与介词 of 连用,表示所属关系,如 'theory of phlogiston';也可与 in 连用,表示存在位置,如 'phlogiston in combustible materials'。

• The concept of phlogiston is outdated.
• Phlogiston was thought to be present in all flammable substances.

语域说明

phlogiston 主要用于学术、历史或科学语境,属于正式词汇,日常对话中较少使用,常见于化学史或科学哲学讨论。

• In historical chemistry, phlogiston was a key concept.
• Modern textbooks mention phlogiston as an obsolete theory.

基础例句

在科学课上,我们学到燃素是关于火的一个旧观念。

People used to think that phlogiston made things burn.

人们过去认为燃素让物体燃烧。

The teacher explained why phlogiston is no longer believed in.

老师解释了为什么人们不再相信燃素。

I read a book that mentioned phlogiston in the history of chemistry.

我读了一本书,里面提到了化学史上的燃素。

高级例句

The phlogiston theory was disproven by Lavoisier's experiments on combustion in the late 18th century.

燃素理论在18世纪末被拉瓦锡的燃烧实验所证伪。

In academic discussions, phlogiston serves as an example of how scientific paradigms can shift over time.

在学术讨论中,燃素是科学范式随时间变迁的一个例证。

The rejection of phlogiston marked a pivotal moment in the development of modern chemistry.

燃素被否定标志着现代化学发展的一个关键转折点。

Researchers often cite phlogiston when analyzing historical scientific errors in peer-reviewed journals.

研究者在同行评审期刊中分析历史科学错误时,常引用燃素作为案例。

常见错误

❌ 错误:Phlogiston is a real chemical element.
✓ 正确:Phlogiston is a historical concept, not a real substance.

错误在于将燃素当作真实存在的化学元素,实际上它是已被证伪的假想物质,正确用法应强调其历史性和理论性。

❌ 错误:We use phlogiston in modern fire experiments.
✓ 正确:Phlogiston is not used in modern science; it's an obsolete theory.

错误在于认为燃素在现代科学中仍有应用,正确用法应指出它已被现代化学理论取代,属于过时概念。

近义词辨析

caloric

caloric 是历史上另一种假想的热质理论中的物质,被认为传递热量,而 phlogiston 特指与燃烧相关的假想物质;两者都是过时的科学概念,但应用领域不同。

Phlogiston was associated with combustion, whereas caloric was thought to explain heat transfer in the 18th century.

aether

aether(或 ether)是历史上假想的充满空间的介质,用于解释光或引力等现象,而 phlogiston 专门针对燃烧过程;两者都是废弃的科学假说,但 phlogiston 更局限于化学领域。

Phlogiston was specific to chemical reactions like burning, while aether was a broader concept in physics for wave propagation.
