A first experiment conducted on various small animals produced encouraging results.

The experiments really should not have produced any result worth mentioning.

Subsequent experiments using these control procedures have produced inconsistent results.

Each experiment produces between 50 and 100 gigabytes of data.

This experiment has produced excellent results even while the units were deployed in the most difficult areas.

Weeks went by, and the experiment produced nothing useful.

Much will depend on what results this mighty experiment produces.

That is now being tried out, and I hope these experiments will produce some useful findings.

As yet no single model seems to account for all the phenomena that experiments have produced.

There is little chance that the experiment will produce a clear answer about whether a vaccine works because too few people are included.
