有些很微妙的因素也能影响到全球的气候变化,譬如说海水的粘滞性。我们都知道,液体有粘滞性,比如当一个物体在水中下沉时,除了水的浮力,还会受到一定的阻力。这个阻力就来自水的粘滞性。液体的粘滞性一般随温度升高而降低。换句话说,同样一个物体,在热水中比在冷水中,下沉时所受的阻力要小一些,所以会沉得更快。我们知道,在海水中,漂浮着许多浮游生物。它们吸收溶解在水中的二氧化碳,然后通过光合作用 Some very delicate factors can also affect global climate change, such as the viscosity of seawater. We all know that liquids have viscous properties, such as when an object sinks in the water, in addition to the buoyancy of the water, it receives some resistance. This resistance comes from the viscosity of water. The viscosity of a liquid generally decreases with increasing temperature. In other words, the same object sinks faster when it sinks in hot water than in cold water. We know that there are many plankton floating in the sea. They absorb carbon dioxide dissolved in water and then pass photosynthesis
