A Study on The Factors Influencing the Facial Apparent Age of Chinese Cosmetic Consumers

To investigate the apparent age of Chinese cosmetic consumers and its influencing factors.The subjects’skin conditions in all dimensions were collected using professional instruments and clinical expert assessment,subjects’lifestyles,skin care and makeup habits were obtained through questionnaire.The apparent age of the subjects was obtained based on the visual perception of photos judged by observers and then averaged.The association between apparent age and skin characteristics,the association between the difference between apparent age and actual age and the subjects'lifestyle and its difference among cities were investigated.The results showed that apparent age had a high correlation with skin tone and severity of skin problems.The model of multiple regression analysis obtained a high resolution(R2=0.704).The use of skin care products may help to delay the apparent aging of the skin.The results of the study have some guiding significance for the development of anti-aging products and the evaluation of anti-aging efficacy and is informative for lifestyle choices to maintain youthfulness.

疏水缔合型丙烯酰胺共聚物P(AA-AM-TP)的制备及溶液性质

疏水缔合型聚合物(HAPAM)具有优异的增黏能力,因此被认为是一种潜在的用于条件苛刻油田的驱油剂。本文以丙烯酰胺、丙烯酸、三苯基-1-戊烯为原料使用胶束共聚法成功制备出一种新型聚合物。研究了聚合物浓度、盐度、温度对溶液黏度的影响。结果表明,当浓度超过1500mg/L时,黏度大幅增高;三元共聚物具有一定的抗温耐盐性质。并使用红外光谱表征了聚合物的结构。
