The results show that the self-consistent BL method can improve theoretically the approximation of molecular field with reliable results provided, also available to the study on the magnetic properties of diluted alloys. 结果表明,自洽Bethe格点方法改进了分子场理论近似,所得结果比较可靠,它适用于研究实际稀磁合金的磁学性质。
The paper applies approximating throry of functional analysis to the space of random function, it spreads linear regression modle to geeral non-linear situation and obtain a strong consistent estimate for regression ( best approximation) coefficient and regression ( best approximation) error. 将泛函分析的逼近论方法运用于随机函数空间,而在此观点下,给出线性回归模型理论的非线性推广,且得到其回归(最佳逼近)系数与回归(最佳逼近)误差的强相合估计。
Consistent Approximation Spaces Based on Dominance Relations Application of dominance rough set in seismology 基于优势关系下的协调近似空间以优势关系为基础的粗糙集在地震数据挖掘中的应用
According to the principle of energy consistent approximation, fundamental equations and boundary conditions for sandwich plates faced with laminated composites are developed by applying the principle of minimum potential energy. 根据能量误差一致原则,应用最小位能原理建立了复合材料面层夹层板的基本方程和边界条件。
It is very interesting to find that the calculations of conformation of chains show that their dimensions in two phase equilibrium state is independent of temperature. This is consistent with the Flory-Huggins approximation but not with K. 有趣的是链构象的计算表明,在两相平衡状态,链的平均尺寸与温度无关,此结果与Flory-Huggins近似相一致,但却与K。

Starting from the Rayleigh diffraction integral and using analytic signal complex representation, the propagation equation of ultrashort pulses in free space has been derived in the near-field beyond the paraxial approximation, which is consistent with the paraxial results in previous literatures if the paraxial approximation is made. 从瑞利衍射积分公式出发,利用复解析信号法推导出了等衍射长度超短脉冲高斯光束在自由空间近场非近轴传输方程,在近轴近似条件下与文献已有的近轴结果一致。
A fully consistent treatment of RRPA with the RMF approximation, i.e. no sea approximation, has to include not only the positive particle-hole excitation, but also the pairs formed from the Dirac states and Fermi states. 与相对论平均场的无海近似自洽,相对论无规位相近似不仅要包含正能态的粒子-空穴激发,还必须考虑Fermi海核子态和Dirac海核子态激发的贡献。
Comparing the covalent electron density of MC with NiAl at different crystal planes, it is found that the electron density along the interface ( 110)_ ( NiAl)// ( 100)_ ( MC) is basically consistent in first-class approximation; 通过对NiAl和MC的不同晶面的共价电子密度的分析发现:(110)NiAl和(100)MC在一级近似范围内基本上保持连续;
