It is proved that the two-dimensional non-hydrostatic Boussinesq equations on the x ? z plane with the kinetic viscous term and the thermal dissipative term are unstable equations in the C 2 function class.2. If we replace the influence of the kinetic viscous term by Rayleigh friction and the thermal dissipative term by Newton cooling, the new generalized equations are stable equations in the C 1 function class. The construction of the solution space and the discriminating method for well-posedness of the problem of determining solution are given.

根据这一算法,发现在时滞的第一个临界值处通过Hopf分支产生的周期解在中心流形上是轨道渐近稳定的,而在其它临界值处通过Hopf分支产生的周期解在中心流形上是不稳定的。

In the process of analytical solution, the divergent item can be give up according to the physical meaning of the solution. But there is no chance to give up the divergent item in the step-by-step integration method. This is why the numerical solution is unstable.

在比较了含有此发散项的该通解的数值结果与平均常加速度法的计算结果后,发现它们是一致的,从而找到了逐步积分法不稳定的原因,即逐步积分法不能避开方程解集中的不稳定子集(从而导致了一种发散性的不稳定)。

The results show that although both Ni substitution and Mg vacancies are effective in desorbing hydrogen at lower temperatures, the substitution of Ni at the Mg site is energetically more favorable than the formation of Mg vacancies. The Ni atoms of NiF2 can replace some Mg atoms of MgH2 systems, the reaction of NiF2+3MgH2=MgF2+Mg2NiH4 during mill process is accelerated, thus, MgH2 with the higher stability can be changed into Mg2NiH4. Because of a ternary hydride Mg2NiH4 with lower stability forming, the dehydrogenating properties on Ni doped MgH2 systems are improved.

结果表明:Ni替代Mg和创造Mg空位对MgH2体系解氢而言,均发挥有益作用,而形成Mg空位所需能量(6.51 eV)高于Ni替代Mg所需能量(2.12 eV),表明低温下Ni替代Mg对MgH2体系解氢而言更有利,至此NiF2中的Ni替代MgH2中的Mg,有利于加速化学反应NiF2+3MgH2=MgF2+Mg2NiH4向右进行,使结构稳定的MgH2发生转变,生成结构不稳定的Mg2NiH4,这样体系解氢过程不是通过MgH2,而是转变为通过Mg2NiH4进行,因此,Ni掺杂提高了MgH2体系的解氢性能。
