The downward curve will go differently in different individual and outside environment. The scientist in The French Larisa Skin Microecology Research Center have worked out a theory which can effetely delay skin aging and recover skin health: help the skin microecology to get into a balanced state by a certain skill from outside, meantime supply new energy to skin, so to slow down the skin aging, and the unhealthy condition of skin also will be improved.

这条下行曲线会因为个体的不同或是外界环境的不同而呈现不同的趋势，法国瑞莎皮肤微生态研究中心的科学家们得出了一个有效延缓肌肤衰老和恢复肌肤健康的理论：从外界设法采取一定手段使皮肤微生态达到平衡，同时为肌肤补充新能量，肌肤的老化速度就会减缓，肌肤的不健康状况就会改善。

The results show that the interplanar crystal spacing and lattice index of Al-rich α phase reduce gradually with increasing pressure. When the pressure reaches from common pressure to 5 GPa , Al-rich α phase lies on the (200) and (220) crystal faces, the interplanar crystal spacing are reduced by 1.07% and 1.15%. From common pressure to 3 GPa , the microstructure of ZA27 alloy changes from thick dendrites to fine dendrites, and finally to granular. According to the effect of solute diffusion coefficient under super high pressure and the calculation of Scherrer formula, it can be seen that the crystal organization is fine within the bounds of certain pressure. This conclusion is consistent with the experiment results.

结果表明：随着压力的增加，晶面间距和晶格常数都逐渐减小，当压力达到5 GPa时，富铝α相在(200)与(220)晶面处，晶面间距较常压力时的分别减小1.07%和1.15%；在常压至3 GPa范围内，晶粒由粗大的树枝晶→细小的树枝晶→粒状、椭球状枝晶转变的趋势，通过压力对合金凝固溶质扩散系数的影响结合Scherrer公式计算分析其组织变化原因，得出在一定的压力范围内，随着压力的增大，晶粒尺寸逐渐变小，这一结论与实验结果相符。
