由题意知$$B=\left { -2,-1,0,1,2,3 \right }$$所以$$ A \cap B= \left { 1,3\right } $$，故选$$\text{B}$$． 
已知集合$$A=\left { \frac{1}{9},\frac{1}{3},1,3,9,27 \right }$$，$$B= {y\left\textbar{} y={{\log }_{3}}x,x\in A \right. }$$，则$$A\cap B$$=．

* $$1$$或$$3$$ 
* $$\left { 1,3 \right }$$ 
* $$\varnothing $$ 
* $$\left { 0,1,2,3 \right }$$
