The specular reflection is a very important linear transformation in Euclidean space, and it has a special geometrical explanation in geometrical space. 摘要鏡面反射是歐氏空間中一類(lèi)很重要的線(xiàn)性變換，在幾何空間中有著(zhù)極其形象的解釋。
The original system with both input and state time delays was first rewritten into a form without any time delays by a nonsingular linear transformation. 為了簡(jiǎn)化變結構控制器的設計，首先通過(guò)非奇異線(xiàn)性變換將含狀態(tài)時(shí)滯和輸入時(shí)滯的線(xiàn)性系統化為無(wú)時(shí)滯系統。
