工科物理虚拟仿真实验教学平台的建设实践

本文介绍了山东科技大学工科物理虚拟仿真实验教学中心建设历程。虚拟方正实验教学中心以山东省实验教学示范中心为依托,以创建国家级虚拟仿真实验教学中心为契机,通过围绕大学物理虚拟仿真平台的建设,从普通物理实验、近代物理实验和专业物理实验等几个方面展开系列工作,并提出虚实结合,有实有虚,实缺虚补的方针,对本校虚拟仿真实验教学方面建设所存在的问题及取得的成绩做了详细的叙述。     

低温工况下结霜对翅片管蒸发器性能影响的实验研究

翅片管蒸发器的结霜将增加空气压降 ,增大传热热阻 ,从而直接影响到蒸发器的效率及空气侧平均换热系数。文中就低温工况下结霜对蒸发器性能的影响进行了测试研究 ,为翅片管蒸发器的设计应用提供了重要依据     

Hamiltonian System of New Nonlinear Lattice Equations

A 3-dimensional Lie algebra sμ（3） is obtained with the help of the known Lie algebra. Based on the sμ（3）, a new discrete 3 × 3 matrix spectral problem with three potentials is constructed. In virtue of discrete zero curvature equations, a new matrix Lax representation for the hierarchy of the discrete lattice soliton equations is acquired. It is shown that the hierarchy possesses a Hamiltonian operator and a hereditary recursion operator, which implies that there exist infinitely many common commuting symmetries and infinitely many common commuting conserved functionals.
