22,(本小题满分12分)解:(1)设M(x,y),由题意得,MO⊥AO,所以MO+O4(=M4上……1分因为圆M的半径为r=y+2=MA|,|AO=2所以x2+y2+4=(y+2),高2分化简得M的轨迹C的方程为x2=4y3分(2)(i)由(1)知:曲线C为:y==,设f(x)=则f(x)=2设圆H与曲线C的公共点为r(2)(>0),则曲线C在T的切线l斜率k=f(0)=由题意,直线1与圆W相切于T点,设圆W的标准方程为:(x-a)2+y2=2(a>0),则直线WT的斜率k=-412t-a 4(t-a)因为l⊥WT,所以1,即r+8(t-a)=024(t-a)又因为(-0)()2=2,所以(-)+(.)=2,所以+4+-128=05分令2=2,则23+42-128=0,所以(花3-42)+(822-128)=0即(λ-4X2+82+32)=0,所以2=4所以t=2,a=3从而圆F的标准方程为:(x-3)2+y2=27(ⅱ)设E(x,片),F(x2,y2),直线l2:y=-x+y=-x+Imx2=4y得:x+4x-4m=0,所以+=4,=一4所以=√x+x2)-4x2=42+m又因为|P=2,2-cm=313=√2m2+12m-10所以4√2(1+m)1+mPQ√-2m2+12m-10分2+6w-5由于l2与曲线C、圆均有两个不同的交点,解得1
