Systematic calculations of low-lying energy levels,B(E2) transitions,and g factors of even-even telluri-um isotopes with mass numbers from 128 to 140 are performed via the nucleon-pair approximation (NPA) of the shell model with phenomenological multipole-multipole interactions.An optimal agreement is obtained between the calculated results and experimental data.The yrast band structures of nuclei below and above the N =82 shell clos-ure are compared and discussed.In particular,the evolutionary differences of B(E2;2+1+ → 0+1) values and g(2+1)factors,with respect to the symmetry of N =82,are attributed to the dominant contribution differences in neutron and proton excitations,respectively.

叶轮机中存在着复杂的湍流流动结构,如何准确地模拟湍流流动一直是工程界关注的核心问题.由于湍流在大部分区域都处于强非均衡态,根据均衡能量传输假设建立起来的RANS湍流模型和大涡模拟亚格子模型都不再适用.非均衡湍流的一个经典的模型流动是尾流,但通常意义上的尾流往往是无数不同尺度相互作用的结果,难以进行简化分析.本文构造了一个极度简化的双尺度尾流模型进行了直接数值模拟(DNS),结果显示在转捩前期就存在反向的非均衡能量传输.分别采用各种传统的RANS湍流模型和大涡模拟亚格子模型进行了数值模拟,发现各种模型都无法

McAllister三体模型的关联性限制了其拓展应用,本文在搜集文献中14类系列型烃类混合物黏度实验数据的基础上,拟合得到了其模型参数.分析发现,McAllister三体模型的两个待定参数(v12与v21)与等效沸点(Tbij)及实验温度(T)间存在一定的规律,由此获得了模型参数的定量推算关系,进而建立了一种具有预测同系列烃类混合物黏度的通用化McAllister三体模型.将新模型的计算结果与实验值进行比较表明,对于所有二元体系的总体平均相对偏差为0.79％,最大相对偏差为7.22％.
