许多生活的机体都是以改变其体内的水分含量和分配来摆脱由热或冷所引起的死亡。如大家所知道的,有些植物、单细胞机体与昆虫,能由丧失水分并增加渗透压,或者单增加渗透压的办法,来增强它们对冷的耐受性。由于这些反应是能够降低体液的冰点的,而冷冻所造成的死亡则是首先由于细胞内结成了冰块,以致原生质的完整性遭到破坏所致,因此这些反应对生命存在的意义来说乃是十分明显的。某些植物也是由预先丧失水分来加强其对热的抵抗的。虽然其机制还没有了解清楚,但是就这些低等生物来说,热或冷所致的死亡是可以简单地归之于全部原生质的不可逆的破坏。这种概念不能引用于高等动物,如恒温 Many living organisms change their body’s moisture content and distribution to get rid of the heat or cold caused by death. As you are aware, some plants, unicellular organisms and insects, can increase their tolerance to cold by losing water and increasing osmotic pressure, or by simply increasing the osmotic pressure. Since these reactions reduce the freezing point of bodily fluids, death from freezing is caused primarily by the formation of ice cubes inside the cells that cause the destruction of the integrity of the protoplasts. Therefore, in the sense of existence It is quite obvious. Some plants also enhance their resistance to heat by pre-losing water. Although the mechanism is not well understood, for these lower organisms, the death caused by heat or cold can simply be attributed to the irreversible destruction of all the protoplasm. This concept can not be cited in higher animals, such as thermostats
