摘要：
The status of planetary nebulae with Wolf-Rayet type central stars ([WR] PN) remains one of the most important problems in the investigation of planetary nebulae. We cannot claim to understand the evolution of low and intermediate-mass stars without answering the question how [WR] PN are created. Analyzing the statistical properties of the whole population of [WR] PN and comparing them to other planetary nebulae (non-[WR] PN) brings important information on their origin and evolutionary status. In this article I will summarize our results of this type of studies and show what limits they put on the possible evolutionary routes of [WR] PN creation.
