Why I get bad bad substitution when using eval?

Why I get bad replace when using eval?

Code:
[river@localhost ate]$ map0=( "0"  "0000"  "0") 
[river@localhost ate]$ i=0
 [river@localhost ate]$ eval echo  \${map$i[1]}
 0000 
[river@localhost ate]$ a=`eval echo  \${map$i[1]}`                            !!!error happens!!!
 bash: ${map$i[1]}: bad substitution

How to resolve it ?
Thanks!
