摘要
盒子（或是支持几个盒子的机箱）可以安装在机动车或是固定的建筑物上。交通工具例如汽车、坦克、轮船或是直升机，当其移动时将产生变形。不太明显的是，考虑到建筑机械、电梯、风力和临近高速公路的影响，即使是假设固定的建筑也会移动和变形。任何结构的变形都有力量作用在盒子或机箱上，
Our box （or r may be attached to Vehicles, such as helicopters, deform ack supporting several boxes） a vehicle or to a fixed structure automobiles, tanks, ships, or as they move. Less obviously, even supposedly fixed structures move and deform Think about the effects of building machinery, elevators, wind loading, and nearby highway inputs. Any structural deformations can exert force on a box or rack and could result in relative motion along originally tight metal seams. Further, a stressed box may move relative to its unstressed doors. Ultimately, apertures will lose their “RF tightness”.
