In the present paper, we have investigated the role of the cosmic string on spin current and Hall electric field. Due to the background cosmic string, the modified electric field of the system generates renormalized spin-orbit coupling, which induces a modified non-Abelian gauge field. The def...
水性漆施工时需要注意以下几个重要的事项: 施工环境:避免在阳光直射和强风下施工,最低环境温度应为5以上 。同时,控制喷涂室、流平室的温度在15-30,湿度在30-75%,温湿度高低都会影响漆膜的表面效果、喷涂性、漆膜的干燥性 。 基面处理:施工前需要清理基面,保证无灰尘、无油渍等 。使用适当的清洁剂...
