普通地使用“焦耳”能在各门科学的研讨中增强一致性并减少混乱。北美洲对于SI推行的阻力正在逐渐减弱,所规定的一系列单位正被人们所接受。但关于SI的许多优点还不是广泛地为大家所理解。这里介绍焦耳作为覆盖物理、化学甚至生物教学中一个“中坚”单位的例子。尽管能量是渗入所有科学的一个概念,但不同学科的教师在介绍它时,不仅形式有区别而且使用的单位也不一样。生物化学家用千 Ordinary use of “joules” can increase consistency and reduce confusion in the study of various sciences. North America’s resistance to SI implementation is gradually weakening, and a series of units are being accepted by people. But many of the advantages of SI are not widely understood. Here Joule is described as an example of a “backbone” unit in physics, chemistry and even biology teaching. Although energy is a concept that infiltrates all sciences, when teachers of different disciplines introduce it, they not only have different forms but also use different units.
