    I created partition over [TransDate] and all the indexes ON DB_PartitionScheme ([TransDate]),but the logical reads of this table and cpu time increase in test db.

    Not surprising.

    I don't know why it is in this way?what should I do?

    Because partitioning is not primarily for performance. It's for maintainability, data loads. You can get performance improvements out of partitioning, but usually not automatically.
