坐标最佳的正方形核素图

Square chart of nuclides with coordinates be the bast

分析了各种核素图中的偶Z =6 0 - 82上界边界线的特征 .说明了在变量Z -N图 ,Z -H图 ,S -H图 ,K -H图与 (S -K) -H图中 ,此偶Z边界线依序由左下向右上递变 ,平竖折线与从右下向左上的边界线 .发现正方形图处于中间位置 ,显示出此图中核素分布规律最优 .对于整个核素区在各种核素图中的范围也是如此 .

It analyzes upper limiting feature of even Z=60-82 in different charts of nuclides.It has illustrated that the break line of upper limiting Z=60-82 in the chart of nucleus with proton number Z and neutron number N,parameters Z and H(=N-Z),two new parameters S(=2Z-N) and H,and parameters K(=S-H) and H,in proper order,it shows that the break line trends from the left lower to the right upper,the line alternates with horizontal and vertical,and the line trends from the right lower to the left upper.Here it finds that the square chart of nuclides places the middle among these charts.It shows that nuclei distribution is concentrated,so are scope of whole region of nuclides in the different charts of nuclides.
