The structure of the channel wave functions of 6Li is studied *** is found that the widths of the low-lying resonances can be in general explained by using shell model wave ***,the width of the 3^(+) state is narrower than that anticipated by the shell modelf thus there is a room for the existence of other physical pictures to describe the very light nuclei.

Based on an analysis of the inherent nodal structures of wave functions of 4-boson systems,we found that the internal energy of the 4_(1)^(+) state should be lower because its structure can be optimized without suffering a strong constraint arising from symmetry(while other 1≤L≤3 states suffer from this kind of constraints).Furthermore,two superior structures favorable in binding are found to be allowed to be possessed by 4^(+) *** findings would lead to the appearance of two adjacent 4^(+) states,as a common feature,in the low-lying spectra of 4 boson systems.

A 60-boson system confined on a sphere has been qualitatively studied based on symmetry considerations. The low-lying spectrum is dominated by the ground rotation band based on the fullerene structure. In this band all the L=1 to L=5 states are found to be prohibited by symmetry. Therefore, there is a large gap lying between the ground state and the first excited state. The magnitude of this gap, which is associated with the critical temperature of Bose-Einstein condensation, has been evaluated. It is found that, the smaller the radius of the sphere of confinement, the higher the critical temperature.

The wavefunctions are decomposed into components. The inherent nodal structure and the stability of these components are investigated. It is assumed that the low-lying states would be dominated by the components without inherent nodal surfaces. Based on this assumption, the composition of the wave functions of the low-lying states of 5He has been suggested and the qualitative feature of the spectrum has been explained.

殉牲是北方牧业人群典型的葬俗特征,殉牲的种类、数量与各地区生态环境和经济生产方式有着密不可分的关系。本文以新店子墓地殉牲动物为研究对象,通过分析殉牲动物的畜群构成特点、年龄和性别结构,结合民族学和现今畜牧业生产方式,认为新店子人群对动物资源的利用具有多样性,主要以获取肉食资源为主,并最大限度地获取乳奶和皮毛资源。针对牧业人群动物资源利用的研究对探究游牧经济生产模式和人地关系具有重要意义。

In this article,we apply blow-up analysis to study pointwise a priori estimates for some p-Laplacian equations based on Liouville type *** newly developed analysis techniques,we first extend the classical results of interior gradient estimates for the harmonic function to that for the p-harmonic function,i.e.,the solution ofΔpu=0,x∈Ω.We then obtain singularity and decay estimates of the sign-changing solution of Lane-Emden-Fowler type p-Laplacian equation-Δp^(u)=|u|^(λ-1)u,x∈Ω,which are then extended to the equation with general right hand term f(x,u)with certain asymptotic *** addition,point wise estimates for higher order derivatives of the solution to Lane-Emden type p-Laplacian equation,in a case of p=2,are also discussed.

基于拉哇水电站溢洪洞采用挑流消能,对陡窄河谷下游边坡冲刷问题进行了试验研究。通过可视定床模型,对边坡水力学参数进行分析,并与边坡动床试验进行了对比。试验成果表明:扭曲挑坎的水流流态、岸边流速以及脉动压力等指标均优于斜切挑坎,岸边最大压力点高程与基岩抗冲流速等值线最低点高程相近;采用散粒体模拟陡峻边坡,边坡冲刷形态与定床岸边流速规律呈现较好的相关性,能较好地反映陡峻基岩边坡受水流冲刷作用的破坏范围。研究成果对类似工程的岸坡支护分区划分、防护深度确定和支护结构型式的设计具有一定的借鉴意义。
