大家都知道,当盐在水中的量超过了饱和度,就不会继续被溶解,而以结晶状态存在着。盐的饱和度还受温度等因素的影响。温度越高溶解的量就越大。如果把盐水迅速冷却到摄氏零度,盐水就会变浑,最后生成结晶。人体新陈代谢所产生的大量废物必须溶解在血液中,通过一定的途径排出体外。据研究,小儿按公斤体重计算所产生的废料大大超过成人。 As we all know, when the amount of salt in the water exceeds the saturation, it will not continue to be dissolved, but exists in a crystalline state. Salt saturation is also affected by temperature and other factors. The higher the temperature the greater the amount of dissolved. If the salt water is rapidly cooled to zero degrees Celsius, the brine will become muddy and eventually crystallize. A large amount of waste generated by human metabolism must be dissolved in the blood, excreted through a certain way. According to research, children’s waste generated by kilogram body weight greatly exceeds that of adults.
