Effect of Magnetic Field and Equilibrium Flow on Rayleigh-Taylor Instability

We investigate the effect of a finite equilibrium flow and magnetic field on the Rayleigh-Taylor instability. It is found that the equilibrium flow only makes a frequency shift of perturbation and the growth rate of the Rayleigh-Taylor instability remains unchanged. However, the magnetic field can change the growth rate and, in particular,a very strong magnetic field suppresses the growth rate.     

非平衡定态相图新概念及其应用——激活低压金刚石气相生长热力学

在激活的低压条件下，金刚石气相稳定生长的同时石墨会被腐蚀．这是近二三十年来国际上的一个热力学难题，甚至被认为是“热力学的悖论”．用非平衡热力学耦合理论可以给予很好的解释，并推导出非平衡定态相图的全新概念．在新型相图中金刚石在低压下是稳定相，而石墨被激活成为亚稳相．理论计算与文献报道的大量实验数据定量化地相符

Ab initio calculations of accurate dissociation energy and analytic potential energy function for the second excited state B1∏ of 7LiH

The reasonable dissociation limit of the second excited singlet state B¹∏ of ⁷LiH molecule is obtained. The accurate dissociation energy and equilibrium geometry of the B¹\Pi state are calculated using a symmetry-adapted-cluster configuration--interaction method in full active space. The whole potential energy curve for the B¹∏ state is obtained over the internuclear distance ranging from about 0.10nm to 0.54nm, and has a least-square fit to the analytic Murrell--Sorbie function form. The vertical excitation energy is calculated from the ground state to the B¹∏ state and compared with previous theoretical results. The equilibrium internuclear distance obtained by geometry optimization is found to be quite different from that obtained by single-point energy scanning under the same calculation condition. Based on the analytic potential energy function, the harmonic frequency value of the B¹∏ state is estimated. A comparison of the theoretical calculations of dissociation energies, equilibrium interatomic distances and the analytic potential energy function with those obtained by previous theoretical results clearly shows that the present work is more comprehensive and in better agreement with experiments than previous theories, thus it is an improvement on previous theories.     

刚性回转体平衡配重方法

机械运转时,除了惯性主轴通过质心,且作等角速转动的回转构件外,所有其它构件都产生惯性力.惯性力在机械各运动副中引起动压力,进而增加运动副的磨损,影响构件的强度,降低效率.此外,周期性的惯性力还造成机械本身的工作精度及可靠性的降低,使零件疲劳破坏并产生噪声.因此,研究机械平衡,消除附加动应力,可以很好地提高产品质量,改善工作环境.
