我们研究了五维平坦时空中静止旋转的封闭Nambu-Goto弦。定常弦被定义为与类时基灵向量相切的世界单。静止弦的Nambu-Goto运动方程在Killing矢量产生的等距群作用量的轨道空间上被简化为测地线方程。我们取一个时间平移矢量和空间旋转矢量的线性组合作为Killing矢量，明确地构造了五维平坦时空中静止旋转闭弦的通解.我们展示了它们的各种构型和性质。
We investigate stationary rotating closed Nambu-Goto strings in five-dimensional flat spacetime. The stationary string is defined as a world sheet that is tangent to a timelike Killing vector. The Nambu-Goto equation of motion for the stationary string is reduced to the geodesic equation on the orbit space of the isometry group action generated by the Killing vector. We take a linear combination of a time-translation vector and space-rotation vectors as the Killing vector, and explicitly construct general solutions of stationary rotating closed strings in five-dimensional flat spacetime. We show a variety of their configurations and properties.
