B.Killed-virus vaccines more closely mimic natural infections than do attenuated live-virus vaccines
C.Killed-virus vaccines pose no risk that vaccine virus might be transmitted to susceptible contacts
D.Killed-virus vaccines are efficacious against respiratory virus infections because they induce good mucosal immunity
E.All above are correct
A.uρ=ucosψ+vsinψ,uψ=-usinψ+vcosψ
B.uρ=ucosψ-vsinψ,uψ=usinψ+vcosψ
C.u=uρcosψ+uψsinψ,v=uρsinψ+uψcosψ
D.u=uρcosψ+uψsinψ,v=uρsinψ-uψcosψ
x=ucosθ-vsinθ,y=usinθ+vcosθ之下,(fx)2+(fy)2是一个形式不变量,即若
g(u,v)=f(ucosθ-vsinθ,usinθ+vcosθ),
则必有(fx)2+(fy)2=(gu)2+(gv)2(其中旋转角θ是常数).

B、H. pylori infection
C、NSAID drugs(aspirin)
D、Alcohol
