研究了辛图模的两个子成分[公式：见文])，其中ν，n为正整数。第一个子成分被证明是一个3-Deza图，除了平凡的情况ν=1，当它是强正则的。当ν大于或等于2时，第二个子成分显示为严格的Deza图。确定了这些图的参数。并给出了这两个子成分的色数和满自同构群。
The two subconstituents of symplectic graphs modulo [Formula: see text] ), where ν,n are positive integers, are studied. The first subconstituent is shown to be a 3-Deza graph except the trivial case ν=1, when it is strongly regular. And when ν⩾2, the second subconstituent is shown to be a strictly Deza graph. The parameters of these graphs are determined. Moreover, the chromatic number and the full automorphism group of these two subconstituents are given.
