In this article, the application of the Quantitative Descriptive Analysis method in the evaluation of the sensory assessment items are studied. With the SPSS reliability analysis, it was found that the Quantitative Descriptive Analysis method is not suitable for some sensory assessment items.展开更多

With the emergence and blowout growth of OTO mode, it is obvious to all of us that there will be more challenges and opportunities in next several decades, especially for the development of cosmetic companies in China. As a matter of fact,many foreign companies have learned to improve the enterprise technology innovation ability by combining all innovation resources from all sides in the global scope.Interdisciplinary integration is becoming closer and closer, and with emerging technologies and cross-industry applications continue to emerge, the world is entering a new era full of subversive ideas with rapid development of intensive innovation and electronic information.展开更多
