To address the problem that the black coating for spacecraft Refrigerator optical stealth easily falls off, this study constructs a light-absorbing spacecraft surface based on a micro/nanostructure through imitating a natural light-trapping structure.In this paper, we first analyze the optical properties of a basic stealth structure with the finite
On the model of a locomotive traction drive in a slipping mode, it Metal Cover is demonstrated how the electromagnetic transient processes in the traction motor may be accounted for using the energy balance method for assessing the stability of the system with respect to frictional self-oscillations.The regions of existence of frictional self-oscil
In the face of excellent survival rates for pediatric and adolescent cancer, preserving the opportunity to have biological Refrigerator children is an important component of long term quality of life.Yet, modern chemotherapeutic regimens continue to pose a threat to fertility.The only fertility preservation methods available to pre-pubertal childre
