I want to design a Non-inverting Precision half-wave Rectifier. This is my design.And I simulate with it but the result is wrong. **broken link removed**

It looks like the OP's circuit should work. It would take two minutes to build on a vector board. Here is a half wave rec circuit I use with a peak detector added in the feedback loop, but the basic half wave circuit is the same.
No. His original circuit will not work as a precision rectifier, as I previously noted. The signal must be go to the inverting input, not the non-inverting input for proper operation.
Edit: If the signal is applied to the non-inverting input, the output will look like a follower for the negative part of the input, so the output will look like an amplified sine-wave for the positive half of the wave, and an unamplified (gain of 1) sine-wave for the negative half of the wave.
