乡村全面增速发展的背景下,要求乡村教师进一步提升身份认同,将高尚的职业情怀和扎实的专业能力投入到乡村教育中去,以高质量的乡村教育助推乡村振兴。荣誉制度是激励乡村教师不断实现个人价值、职业价值和社会价值的有效手段,其直接产生了作为媒介的荣誉感,荣誉感与身份认同相互联结并发生作用。身份认同中的三个内涵对荣誉制度的建设产生助力,自我认同要求荣誉制度引导教师明确教书育人的职业价值所在,群体认同需要荣誉评选具备程序正义,社会认同则要求荣誉制度应致力于提升教育质量以服务乡村振兴的宏观目标。但当前乡村教师荣誉制度仍存有称号设置不合理、评选程序失当和誉后管理缺位等问题,应当立足于身份认同提升理论,通过设计科学的荣誉称号体系、完善荣誉评选过程的各项标准和加强获誉乡村教师后续培养等方式建构乡村教师荣誉制度,为乡村振兴持续注入充沛活力。

量子力学创立伊始,狄拉克就关注到了一般表示的问题,其后量子力学的发展又引入了福克态、相干态等表示。好的表示应能提供正交归一的完备基,同时又能给出问题的严格解析解或者允许方便地得到近似解,但这常常是做不到的。我们意识到此前得到的相干态正交化方法恰恰满足表示理论的一般性要求,且因为包含自由参数为构造归一化的完备正交基实际上提供了无限的选择,这样甚至在解决问题的过程中都可以灵活地选择不同的表示,从而带来计算量的大幅减小。通过对不同耦合强度下的近共振态Rabi模型最初10个能级的计算,并同关联的JC模型的结果相比较,验证了相干态正交化方法的有效性。
