According to the difference in the compositions of various atomic nuclei, more than 2250 kinds of atomic nuclei have been discovered. Several millions of nuclear characteristic parameters have been obtained from experiments. By comprehensively investigating the characteristics of nuclides and the compositions of atomic nuclei, can we get a systematic understanding of various atomic nuclei? The new chart--- "valley-like" chart of nuclides is the answer to this question and it's the basis for further study as well.
