In light of recent advancements in synchrotron radiation technology and nano-technology. there has been a marked increase in the need for ultra-precision nano-positioning mechanisms. This paper presents a method that integrates physical models with multi-objective optimization for developing an optical angle nano-positioning mechanism. We begin by examining the actual motion law of th... https://countryscenesaddleryandpetsuppliers.shop/product-category/youth-jeans/
