摘　　要：利用经典导心轨道程序ORBIT,结合平衡程序EFIT和输运程序TRANSP,计算了EAST中性束注入后快离子的损失情况。结果表明,4MW(80keV)氘离子的损失份额为29%,2MW(50keV)氘离子的损失份额为31%,损失的快离子有很强的局域性。By means of classical guiding center orbit code ORBIT and combining with equilibrium code EFIT,as well as transport code TRANSP,the loss of neutral beam injected fast ions in EAST is calculated.29% and 31% of the injected neutral beam ions were lost,with the beam power and energy given by 4MW（80keV） and 2MW（50keV）,respectively,and the lost fast ions are strongly localized.
