The authors investigated the singular limits of stiff relaxation and dominant diffusion for general 2×2nonlinear systems of balance laws, that is,τ=o,ε→ 0, the relaxation time τtends to zero faster than the diffusion parameter ε. If there exists a priori L∞ bound that is uniformly with respect to ε for the solutionsof a system, then the solution sequence converges to the corresponding equilibrium solution of the system.

研究一般扩散占优的2×2双曲平衡律系统奇异松弛极限，用补偿紧性方法，在松弛时间τ比扩散系数ε趋于零快时，即τ=o，ε→ 0时，得到其解的整体存在性一般框架：如果上述系统的解存在对ε一致的先验L∞估计，则其解序列收敛于上述系统的对应平衡状态解。

In this thesis thecurrent situation and future of the aged has been analyzed mainly, seven characters werediscussed as followed: trend of aging phenomenon, high growing speed of this phenomenon,big absolute unit of population, un-equilibrium distribution in the whole country, low healthylevel, exceeding economic development. The influence on economy, society, family,psychology and so on had been discussed also. It pointed out the importance of stabilizing thebirth level, performing new trinity mode of providing for the aged by themselves, by thesociety and by their children, taking actions to delay the aging speed correspondingly andfulfilling elementary service for their health.

We have found that a likewise capital market with stocks and loans being the major means to save for the future and gain capital accruement has the inner vulnerability—that is, if the former market equilibrium has been disturbed, the market has the inclination to fall down or go up continuously.

发现：一个没有套期保值机制的以股票和信贷为资产增值和储蓄手段的资本市场具有内在的"脆弱性"（一旦原有市场均衡被打破，市场有持续下跌和持续上涨的倾向）。

The problems of the heat transfer equation of cloud drop growth were analyzed from chemical potential and principle of phase equilibrium of multi-component system. It was pointed out that Clapeyron equation was the result gained under the condition of rigid phase equilibrium. It only shows the linear relation between steam press and temperature at saturation state, and does not show that there is any thermodynamic process which can meet this equation.

基于多元体系化学势和相平衡原理，分析了云滴长大热传导方程存在的问题，指出克拉伯龙方程是严格相平衡条件下推导出的结果，仅表示饱和状态下蒸汽压与温度之间的线性关系，并不表示存在满足克拉伯龙方程的热力学过程。
