黄河下游流域与文化的界定,是黄河文化研究中的一个重大问题。论者将黄淮海平原的广阔区域都作为黄河下游流域的传统看法是不恰当的。淮河作为一条大河,自有其独立的流域范围,“夺淮入海”时期,黄河夺占淮河支流和主河道,主要系人为因素改道和维持所致,且多为河道游移、水系混乱的“地上河”,并未形成自己的“集水区”;在文化上,淮河文化是长江文化的亚文化,在春秋战国时期是长江楚文化的重要组成部分。故无论从流域还是文化上看,淮河流域都不能作为黄河下游流域看待。泰沂山西延伏脉以北的华北平原,是黄河天然形成的入海之地;在秦汉以前,是中华文明起源、三代文明奠基的重要区域之一,是春秋战国时代的文化重心,是实现秦汉“大一统”的经学繁荣基地和思想库。该地区在中华文明起源、形成及中华民族共同体奠基的重要历史时期作出了突出贡献,是奠定黄河文化为中华民族“根”与“魂”的核心区之一。华北平原及其文化就是黄河下游的流域与文化。

为探究苦参碱能极大增强黄芩苷在水中的溶解度的原因,采用量子计算对二者反应过程及共存状态进行分析,并使用单晶衍射和红外图谱验证计算结果.本研究表明,黄芩苷和苦参碱并非简单的以非共价作用相结合,二者存在质子转移现象,反应生成黄芩苷阴离子和苦参碱阳离子,以静电作用为主导形成共无定型物,导致水溶性极大增加.

Total atomic scattering factors for the 1s^23s ^2S stages for the lithium isoelectronic sequence from Z = 3 - 10 are calculated by using the full core plus correlation wave function. The influence of electron correlation on total atomic scattering factors is considered sufficiently in our calculation. For the 1s^2 3s ^2S states of the lithium isoelectronic sequence, the general functional behaviour of total atomic scattering factors is analyzed together for each state of the isoelectronic sequence.

This paper describes an approach for predicting the diameter of a jet-grout column using the support vector regression(SVR)technique,which is regarded as a novel learning machine based upon recent advances in statistical theory,in which the combined effects of the construction(construction methods and jetting parameters)and soil properties(soil type and shearing resistance)are *** different kernel functions,namely,a linear kernel function,polynomial kernel function,radial basis kernel function,and sigmoid kernel function,are integrated into the SVR technique.A large amount of field measured data on the diameter of jet-grout column are retrieved from the published literature for training and testing *** results indicate that the SVR technique with a radial basis kernel function provides predictions closest to the measured results,whereas the prepared design charts enable the ability to significantly widen the application of the proposed approach to the areas of ground improvement and environmental protection.

We find that in a supersymmetric quantum mechanics （SUSY QM） system, in addition to supersymmetric algebra, an associated SU（2） algebra can be obtained by using semiunitary （SUT） operator and projection operator, and the relevant constants of motion can be constructed. Two typical quantum systems are investigated as examples to demonstrate the above finding. The first example is the quantum system of a nonrelativistic charged particle moving in x-y plane and coupled to a magnetic field along z-axis. The second example is provided with the Dirac particle in a magnetic field. Similarly there exists an SUτ（2） SUσ（2） symmetry in the context of the relativistic Pauli Hamilt onian squared. We show that there exists also an SU（2） symmetry associated with the supersvmmetrv of the Dirac particle.
