I can tell you indeed it is, because this type of spectrum, just like what you've seen in books, and just like what you've seen in amino acids, it doesn't really matter how you change the environment, it's very robust; it's going to reflect the environment.
是的 因为这种分布，就如刚刚的书 和氨基酸一样 不管你怎么改变环境，特征十分明显 会反映环境
