我们构造了六维异质运动方程的新的显式紧凑超对称有效解，该解具有非零场强、非平坦瞬子和常数膨胀。我们提出了六维紧致尼尔流形上的平衡埃尔米特结构，满足具有非零通量、非平坦瞬子和常数膨胀的异质超对称方程，该方程服从三型比安奇恒等式，曲率项取自列维-奇维塔、(+)-连接或陈连接。其中，我们关于紧尼尔流形M3上的(+)-连接的所有解都满足杂态运动方程。
We construct new explicit compact supersymmetric valid solutions with non-zero field strength, non-flat instanton and constant dilaton to the heterotic equations of motion in dimension six. We present balanced Hermitian structures on compact nilmanifolds in dimension six satisfying the heterotic supersymmetry equations with non-zero flux, non-flat instanton and constant dilaton which obey the three-form Bianchi identity with curvature term taken with respect to either the Levi-Civita, the (+)-connection or the Chern connection. Among them, all our solutions with respect to the (+)-connection on the compact nilmanifoldM3satisfy the heterotic equations of motion.
