摘　　要：主要介绍了利用兰州重离子加速器提供的270 MeV的40Ar离子束轰击238U靶,通过熔合蒸发反应进行试合成Z=110附近的新同位素的实验情况。分析了目前关于超重核研究的现状并描述了这次实验的目的、可行性分析、实验装置以及实验过程等。本次实验仍然用氦喷嘴技术对产物进行传输,并用一套具有数对探测器组的转轮收集探测系统对产物进行收集和测量。The state of the experiment to produce the new isotopes around Z~ 110 are presented in this paper. The emphasis is laid upon introducing the experiment purpose, the set-up and the feasibility for producing this objective nuclide. In the experiment the new isotopes were produced by the complete fusionevaporation reaction of 2ssu with 270 MeV 40Ar at the Sector Focus Cyclotron.（SFC） of Heavy Ion Research Facility in Lanzhou（HIRFL）. The reaction products were also transported and collected by using the helium-jet technique and rotating wheel apparatus.
