We consider the(2+1)-dimensional nonlinear Schr?dinger equation with power-law nonlinearity under the parity-time-symmetry potential by using the Crank-Nicolson alternating direction implicit difference scheme,which can also be used to solve general boundary problems under the premise of ensuring accuracy.We use linear Fourier analysis to verify the unconditional stability of the scheme.To demonstrate the effectiveness of the scheme,we compare the numerical results with the exact soliton solutions.Moreover,by using the scheme,we test the stability of the solitons under the small environmental disturbances.

Using an extended version of quantum hadrodynamics,I propose a new microscopic equation of state (EoS) that is able to correctly reproduce the main properties of symmetric nuclear matter at the saturation density,as well as produce massive neutron stars a
研究了气动力-安培力-受迫激励联合作用下载流新月形覆冰导线的振动特征,在传统只考虑安培力的载流导线振动方程中引入了气动力和受迫激励项,使得模型更加符合实际工程.首先建立了载流新月形覆冰输电导线模型,接着推导了载流覆冰导线模型的振动方程,利用Galerkin方法将该振动方程转变为有限维度的常微分方程,采用多尺度法进行摄动求解,求得幅-频响应函数,并对比分析主共振情况下考虑气动力与不考虑气动力时载流、间距、风速、张力、激励幅值对振动幅值的影响.研究结果表明:考虑气动力的振动幅值较未考虑气动力时小.各线路参数对
自密实混凝土的Ⅱ型断裂韧度是个很重要的材料参数,而对其Ⅱ型断裂的研究,有助于我们建立复杂裂缝扩展准则并且探索构件断裂失效.为了解自密实混凝土Ⅱ型断裂破坏过程并确定其Ⅱ型断裂韧度,本文制备了7组21个不同缝高比以及不同切口方式的试件,利用半对称加载方式对自密实混凝土做了Ⅱ型断裂实验,并利用ABAQUS有限元建模,模拟计算了各个试件的Ⅱ型断裂韧度.实验结果表明,自密实混凝土比普通混凝土粒径小,断裂脆性大,多是沿韧带剪切破坏,自由端剪切崩落.实验与模拟计算的Ⅱ型断裂韧度一致,其大小为1.95 MPa.√m.由于
本文基于四根刚臂梁结合12个外接一维单元建立了钢筋混凝土框架节点单元,单元具有5个节点15个自由度,称之为“BCJ-5N”单元.每个节点具有3个自由度,与普通梁单元一致,从而确保本单元适合于同普通一维梁柱单元一起进行钢筋混凝土结构平面非线性分析.单元考虑了梁受力钢筋在框架节点内的黏结滑移作用,并通过钢筋混凝土梁正截面强度设计建立了梁端弯矩与截面转角关系的骨架曲线,结合Lowes加载卸载模型,组成了完整的静力、动力分析的框架节点单元,并将其移植到ABAQUS通用分析平台上,通过对两跨三层钢筋混凝土框架结构的
We theoretically investigate the vortex patterns in photoelectron momentum distributions of He+driven by counter-rotating elliptically polarized,time delayed attosecond laser pulses by numerically solving the two-dimensional time-dependent Schr(o)dinger e
Nuclear deformations are fundamentally important in nuclear physics.We recently developed a multidimensionally constrained relativistic Hartree-Bogoliubov (MDCRHB) model,in which all multipole deformations respecting the V4 symmetry can be considered self
The Bohr Hamiltonian with axially deformed shape confined in a quasi-exactly solvable decatic β-part potential is studied.It is shown that the decatic model can well reproduce the X(5) model results as far as the energy ratios in the ground and beta band
光滑粒子流体动力学(SPH)是一种拉格朗日型无网格粒子法,粒子均布程度是影响SPH分析精度和稳定性的重要因素.本文基于射线法提出了一种在异形多边形区域内均布SPH粒子的方法,先在多边形的最小外包矩形范围内均布粒子,再通过射线法和辅助筛选条件保留区域内的粒子;通过生成粒子的Voronoi多边形计算其变异系数值(Cv),作为SPH粒子均布质量的评价标准,其值越小,粒子均布质量越高.为验证该方法提高分析精度的有效性,基于爆轰侵彻的经典实验,建立由经典三角形和四边形均布粒子法构建的模型甲、模型乙和本文模型丙,用L
The infinite derivative theory of gravity is a generalization of Einstein gravity with many interesting properties,but the black hole solutions in this theory are still not fully understood.In the paper,we concentrate on studying the charged black holes i
基于广州北站综合交通枢纽一期广清城际铁路广州北站站房工程,对在既有广铁九号线旁进行基坑开挖的影响进行研究.根据工程与地铁的位置关系、周边环境、地质条件以及施工工序等,利用三维有限元软件建模,对照基坑墙顶水平位移、地表沉降等工程监测数据分析与评估广清城际广州北站站房工程施工对周围环境产生的各种影响.研究发现,墙顶水平位移相对较大的点位往往位于基坑围护的中部,较小的点位往往位于基坑围护的角点部位,基坑的时序开挖会引起周围土体位移场和应力场的叠加增大,因此基坑开挖时的后开挖区域往往是基坑的最大影响区,地表沉降与
