双语版 TED-Ed 演讲精选 Henry's law states that the amount of a gas that dissolves in a liquid is proportional to its partial pressure. 亨利定律说,气体在液体中的溶解度是与它的分压成比例的。 Veritasium真理元素 To function normally, humans need an oxygen partial pressure of at least 16 kilopascals. 为了正常运作,人类需要至少16千帕的氧分压。 Crash Course 综合篇 You see how that last formula looks a lot like the one for partial pressures? 您看到最后一个公式看起来很像分压公式吗? 呼吸系统 Each gas diffuses down its own partial pressure gradient - that is, from a high to low partial pressure. 每种气体都会沿着它自己的分压梯度扩散——也就是说,从高分压扩散到低分压。 Crash Course 综合篇 With correct rounding, that will give you a partial pressure of 21 kilopascals for oxygen. 通过正确的舍入, 这将为您提供 21 千帕的氧气分压。 Crash Course 综合篇 What is the partial pressure of O2 in air at a total atmospheric pressure of 97.8 kPa? 在总大气压为 97. 8 kPa 的情况下, 空气中 O2 的分压是多少? 呼吸系统 The partial pressure gradient of each gas equilibrates as blood flows through the pulmonary capillaries. 当血液流过肺毛细血管时,每种气体的分压梯度趋于平衡。 Crash Course 综合篇 It’s not just the pressure outside of the solvent, it’s the partial pressure of the solute. 这不仅仅是溶剂外部的压力, 而是溶质的分压。 Crash Course 解剖生理学篇 They burn through it quickly, lowering the oxygen partial pressure around them to about 40 millimeters. 它们迅速燃烧,将周围的氧分压降低到大约 40 毫米。 Crash Course 综合篇 Quick review: partial pressure is the portion of pressure caused by the gas we’re interested in. 快速回顾:分压是由我们感兴趣的气体引起的压力部分。 Crash Course 综合篇 Because the normal partial pressure of CO2 in the atmosphere isn’t enough to keep it from escaping. 因为大气中二氧化碳的正常分压不足以阻止它逸出。 Crash Course 解剖生理学篇 So, partial pressure gives us a way of understanding how much oxygen there is, based on the pressure that it's creating. 所以,基于它产生的压力,分压给我们一种了解有多少氧气的方法。 Crash Course 解剖生理学篇 BUT! Partial pressures are only part of what's prodding your hemoglobin to give up the goods. 但是!分压只是促使血红蛋白放弃商品的一部分。 Osmosis-呼吸 This is because the mucus plugs in the airways block air flow, right, which causes the partial pressure of CO2 to increase in the lungs. 这是因为黏液阻塞了气道导致气流无法通过,对吧,这导致了肺里的二氧化碳分压增高。 呼吸系统 As equilibrium is always achieved across the respiratory membrane, the partial pressure will increase in the blood as well. 当平衡总是通过呼吸膜实现时,血液中的分压也会增加。 Crash Course 解剖生理学篇 Well, a lot of it has to do with a principle of chemistry known as partial pressure. 这在很大程度上与一种叫做分压的化学原理有关。 Veritasium真理元素 Meaning the partial pressure of oxygen was only 16 kilopascals, the minimum required for people on the plane to feel normal. 这意味着氧气分压只有16千帕,这是飞机上的人感觉正常所需的最低值。 呼吸系统 What is responsible for this drop in partial pressure? 分压下降的原因是什么? 呼吸系统 The partial pressure of oxygen is 100 mmHg in alveolar air compared to only 40 mmHg in the blood entering the lungs. 肺泡空气中的氧分压为100 mmHg,而进入肺部的血液中只有40 mmHg。 呼吸系统 The partial pressure of carbon dioxide is 40 mmHg in the alveolar air and 45 mmHg in the blood entering the lungs. 肺泡空气中的二氧化碳分压为40 mmHg,进入肺部的血液中的二氧化碳分压为45 mmHg。 |
