从外观看,人在大体上都是左右对称的,显然,这种外观对称应该是美感的一个必要条件,但是,人的这种对称美,却没做到表里如一,因为人的内脏就不是左右对称的。例如心脏、肝脏等分布在体内的一侧,而肺尽管同时分布在两边,但仍然左右不对称,只有肾、卵巢等少数器官大体上才是左右对 From the outside, people are generally symmetric about each other. Obviously, this symmetry of appearance should be a necessary condition for beauty. However, this symmetry of beauty is not exactly the same, because human internal organs are not Symmetrical. For example, the heart and liver are distributed on one side of the body. Although the lungs are distributed on both sides at the same time, they are still asymmetrical. Only a few organs such as the kidney and ovary are generally left and right.
