DESPRIPTION】 This product adopts natural activated Collagen Peptide as its ingredient, and combines the SAYF(skin activate and youthful factor) and micro spinning technology of elastic fiber to make the eye pact perfectly fit around the eye contour, It can quickly supplement skin moisture and provide quick penetration of nutrient substance to the stratum basale under the guide of the nutrient substance penetrating absorption principle, as well as promote the vitality of skin cells, 95% of which will efficiently absorb and reserve moisture and balance PH value to make the skin elastic and soft, and significantly improve low collagen synthesis which is related to aging. It can also efficiently prevent and reduce eyes' skin wrinkles and cutis laxa to restore the eyes' skin moist and elastic, and implement the nutrition lost because of the fluctuations in temperatures to promote the natural moisture ability of the skin around the eyes to make those skin instantly moisturized, smooth, refresh and outstanding radiant. The wrinkles and fine lines will be reduced at the same time, and the black circles will be no longer apparent.

Weibull distribution function is used to characterize phenomenologically the debonded probability of the interface, which is decided by the tensile stress of the particle. A partially debonded isotropic spherical elastic particle is replaced by an equivalent, perfectly bonded spherical particle, which possesses yet unknown transversely isotropic elastic moduli. The fictitious particles can be determined in such a way that their tensile and shear stresses will only vanish in the debonded direction.

认为颗粒增强金属基复合材料的界面脱黏受控于颗粒所受的拉应力，引入Weibull分布函数描述颗粒脱黏概率，且受单向拉伸载荷作用时，仅在沿受力方向的上下两侧发生部分界面脱黏，从而将部分脱黏的各向同性颗粒由一完好的横观各向同性颗粒来等效，建立了部分脱黏模型。
