狗靠鼻子过日子。那狗的鼻子到底有多厉害呢!来看一组数据:和人类相比,狗的嗅觉细胞总数是人类的40~100倍,狗的嗅觉灵敏度是人类的100~100万倍。所以,狗的鼻子比人类的鼻子灵得多。不光和人类相比是这样,狗的鼻子在所有动物中也是最灵的。这具体表现在以下两点:1.对气味的敏感程度高。狗对气味的感知能力可达到分子水平。比如在500千克水中溶入1小匙食盐,或者在500千克水中加入1汤匙醋酸,它也能嗅出。
Dogs live by the nose. Look at a group of data: compared with humans, the total number of dog’s olfactory cells is 40 to 100 times human, the sense of smell of dogs is 100 to 1 million times human. Therefore, the nose of a dog is much greater than the human nose. This is not the case with humans alone; the dog’s nose is also the most spiritual of all animals. This is specifically manifested in the following two points: 1. Sensitivity to the smell high. Dog’s perception of smell can reach the molecular level. For example, dissolve 1 teaspoon of salt in 500 kilos of water or 1 teaspoon of acetic acid in 500 kilos of water. It also sniffs out.
