Storage alignment optimization is put forward based on studying the storage mode of automated stereoscopic warehouse,and a mathematic model of storage alignment optimization is built up according to the lowest energy principle of goods storage.

Based on SVD(Singular value decomposition) and the energy minimum principle,an adaptive image denoising algorithm is proposed in this paper.

In this article,we recall the development of principle of treatment of fracture and present method of femoral neck fracture to discuss the optimal method of it in elderly patient by using the principle of optimization.

To discuss the ethical meaning of the principle of optimization, which embodies medical aim, reflects the ideal of professional morals, and shows loving care for the patients.

It is essential to strengthen the application of the optimization principle of diagnosis and treatment in clinical practice teaching,which can improve the quality of medical treatment and build a harmonious and mutual-trust relationship between doctors and patients so as to better serve patients and promote the development of medical science.
