摘　　要：用气喷咀反冲传输技术将14MeV中子引起^(288)U裂变的裂变产物从照射位置传输到15m远的实验区.氮气作传输气体,KCl作添加剂.活性炭和混合纤维素酯微孔滤膜作阻止、吸附材料.Ge(Li)探测器测得的12个核素的传输效率大都在40—70％之间。The gas-jet recoil transport system has been used to transport fission products from the 14.8 MeV neutron induced fission of 238U. Nitrogen was used as transport gas and KCl as a cluster producer. The fission product activities were stopped and retained in the column of charcoal or the trap of polyester fiber filters. Most of the overall transport efficiencies were determined to be 40-70%.
