说明：  纯SU（2）guge理论。我们提供生成配置、计算可观测值和固定量规的例程。我们的重点是团队的核心。SU（2）矩阵通过其与向量（a1，a2，a3，a4）的同构来描述，并且我们实现了处理该参数化所需的代数函数。
(Pure SU(2) guge theory. We provide routines to generate configurations, compute observables and fix gauges. Our focus are on the center of the group. The SU(2) matrices are descrebed by its isomorphism with the vector (a1,a2,a3,a4), and we implement the need algebraic functions to deal with this parametrization.)
