我们研究了杂合弦的轨道紧化的环面上的规范背景场的存在的后果。指出这种Wilson线为我们提供了一种控制旋光和非旋光扇区中手征物质态的数目以及对称群破缺的机制。从Z轨道开始，我们可以用三个夸克族和轻子族以及不同的规范群，如E6、SU（3）3、SU（6）× U（1）或SU（5）× [SU（2）× U（1）]2，构造各种四维弦模型。
We study the consequences of the presence of gauge background fields on the torus underlying orbifold compactification of the heterotic string. It is pointed out that such Wilson lines provide us with a mechanism for controlling the number of chiral matter states both from twisted and untwisted sectors, as well as breaking the symmetry group. Starting from the Z orbifold, we can construct a variety of four-dimensional string models with three families of quarks and leptons and different gauge groups such as E6, SU (3)3, SU (6) × U (1) or SU (5) × [SU (2) × U (1)]2.
