Abstract: The implementation of the new Criminal Procedure Law indicates that the expert assistant system has been officially established in China’s criminal procedure. The expert assistant system has been carried out in civil procedure for thirteen years, but it has not been used frequently in civil cases. Moreover, the rules and regulations about expert assistants in criminal procedure are too general to apply. In order to provide some opinions for the implementation of the system in criminal procedure, this article tries to discuss some key issues regarding the expert assistant system in criminal procedure, including the essence of the examination of the opinion of forensic experts, the function and selection of expert assistants, and the evidential properties and the management of the opinion presented by expert assistants. 

Key words: expert assistant, opinion of forensic expert, opinion of expert assistant 

摘要： 随着2013年《刑事诉讼法》的实施，我国正式确立了刑事诉讼领域的专家辅助人制度。专家辅助人制度虽然在民事诉讼领域已推行了13年，但实践经验乏善可陈，刑事诉讼领域的立法又过于原则，缺乏可操作性。因此，拟对刑事专家辅助人制度的几个关键问题进行讨论回应，以期对该制度在刑事诉讼中的顺利实施提供参考借鉴。首先讨论的是对鉴定意见审查质证的本质问题，其次是专家辅助人的功能及其遴选问题，第三是专家辅助人意见的属性及其管理问题。
