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%.

We have calculated the mass spectra for the (D)(*)sD(*) molecular states and sc(qc) tetraquark states with JP =0+,1+,2+.The masses of the axial-vector (D)sD*,(D)*sD molecular states and 1[se]⊕0[(qc)],0[sc]⊕ 1[(qc)]tetra-quark states are predicted to be ap
The BLMSSM is an extension of the minimal supersymmetric standard model (MSSM).Its local gauge group is S U(3)C × S U(2)L × U(1)y × U(1)B × U(1)L.Supposing the lightest scalar neutrino is a dark matter candid-ate,we study the relic density and the spin in
The magnetic moment (aγ) and weak magnetic moment (aw) of charged leptons and quarks are sensit-ive to quantum effects of new physics heavy resonances.In effective field theory,aγ and aw are induced by two in-dependent operators.Therefore,one has to measu
One method of probing new physics beyond the Standard Model is to check the correlation among high-er-dimensional operators in the effective field theory.We examine the strong correlation between the processes pp--→ tHq and pp-→ tq,which both depend on th

We study the decay of the SM Higgs boson to a massive charm quark pair at the next-to-next-to-leading order QCD and next-to-leading order electroweak.At the second order of QCD coupling,we consider the exact cal-culation of flavour-singlet contributions w
A rovibrational model,including anharmonic,centrifugal,and Coriolis corrections,is used to calculate π,K,N,and ∑ orbital and radial resonances.The four orbital excitations of the π meson correspond to the b(1235),π2(1670),b3(2030),and π4(2250)resonances.I
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
