填空题1.国际单位制(SI)中,长度的基本单位是符号是 。 常用的长度单位还有g等。2.单位换算100 cm=m mm=nm;2 ×103 m=km=mm。3.用刻度尺测量时,尺要所测物体;不要用已的零刻度线;读数时视线要与尺面 ;测量结果由和组成。4.测得的数值与之间的差异叫误差。可以减小误差。5.误差在测量中 ,但可以减小...
(1) 通过NQA监测地址192.168.0.88是否可达。(2) 如果192.168.0.88可达,则认为该静态路由有效,NQA不通知Track模块改变Track项的状态;如果NQA发现192.168.0.88不可达,则通知Track模块改变Track项的状态。(3) Track模块将改变后的Track项状态通知给静态路由模块。静态路由模块据此可以判断该静态路由项是否有效。

Substrate-dependent valency of Yb chemisorbed onto Si(111)7×7, Si(100)2×1, anda-Si surfacesYb chemisorption at monolayer coverages onto Si substrates is the precursor stage of Yb/Si interface formation. Ytterbium is divalent as a... G.,Rossi,D.,... - 《Physical Review B》 被引量:...
A detailed study of the early stages of nucleation and growth of Ag on Si(100)-(2×1) surfaces at room temperature using ultrahigh-vacuum high-resolution transmission-electron-microscopy imaging and diffraction is presented. While diffraction patterns suggest only a mixed epitaxy, off-zone axis im...
