| 摘 要： | 1. IntroductionThe measurement of H./D. emission, which canafford much information of the plasma, is one of the-,primary diagnostics in tokamak experiments. If theintensity Of H./D. emission along different chords ina poloidal plane are measured, with the ABEL inver-sion, one can get the H./D. emissivity, thus the spatial distribution of neutral H/D and its penetrationor ionization length. With the absolute brightness ofH./D. emission and assuming some symmetries inspatial distribution, …
