To improve the measuring precision of the automobile caster by a linear model on the four-wheel aligner, a precise measuring model was built. 摘要針對四輪定位儀采用線(xiàn)性模型測量主銷(xiāo)后傾的誤差問(wèn)題，建立了精確的測量模型。
Through a typical quantum measurement model, we study the relation between decoherence of a central two-level system and quantum phase transition in its environment. 通過(guò)一個(gè)典型的量子測量模型，我們研究了一個(gè)二能級系統的退相干與和他耦合的環(huán)境的量子相變之間的關(guān)系。
