muether meaning in Chinese

米特尔

Very recently , schiller and muether at tubingen university suggested a new decomposition approach of the dbhf g matrix , and used to calculate the nucleon self - energy . they , sepa rate the g matrix into a bare nucleon - nucleon interaction v and correction term a g . the projection method is only applied to the correlation term a g , which is parameterized by four pseudo - mesons . then the nucleon self - energy in the dbhf can be calculated with the g matrix in the relativistic hartree - fock approximation
裸相互作用部分，即单玻色子交换势v对核子dirac自能结构的贡献可以通过相对论hartree - fock方法得到，只把关联部分用投影方法处理，并参数化为四种具有无穷大质量赝介子的交换，耦合常数与质量的比值是常数，从而关联部分g对核子自能的贡献也可以通过相对论hartree - fock方法求得。
There are several ways to obtain the dbhf self - energy from the g matrix used before , such as a simple method , where the dirac structure of the nucleon self - energy is obtained from the momentum dependence of the single - particle energy , and a projection method . all of them have their drawbacks
通常的从动量依赖的单粒子能量中提取自能的办法和投影方法都具有一定的局限性，最近，由schiller和muether发展了提取核子自能dirac结构的新方法，即把g矩阵分解为裸相互作用部分v和关联效应部分g 。
