It maybe vopt by ModelSim.

 

 uncheck "compile -> compile options-> Use vopt flow "  in modelsim, and  try again

chenhongyi123 ,thanks for your reply! 

 

and I still cann't solved the problem. I found it strange that when my design was not including sequential logic,such as 'always'sentence, the output can be seen at the waveform.

hope somebody can give me a hand.
