在线性等离子体装置氚等离子体实验（TPE）中研究了靶材料和温度对Balmer系列发射的影响。靶体质量越大，靶体温度越低，靶体前方Balmer系列发射强度越大，发射强度与氢反射系数呈较好的线性关系。对于Ti和Ta的放热型氢阻挡剂，Dβ/Dα的强度比随着靶温度的升高而显著增加，而对于Ni、Cu和w的吸热型氢阻挡剂，Dβ/Dα的强度比基本保持不变，这清楚地表明靶材料和靶温度改变了边界等离子体。此外，强度比Dβ/Dα不仅是等离子体温度的函数，而且具有明显的靶温依赖性。
We have investigated the influence of target materials and temperatures on Balmer series emission in a linear plasma apparatus, Tritium Plasma Experiment (TPE). The intensities of the Balmer series emission in front of the target were higher for heavier mass target and also for lower target temperature, showing rather linear relationship between the emission intensity and hydrogen reflection coefficient. For exothermic hydrogen occluders of Ti and Ta, the intensity ratio of Dβ/Dα increased with the target temperature markedly, whereas the intensity ratio stayed rather constant for endothermic hydrogen occluders of Ni, Cu and W. This is a clear demonstration that the target materials and temperatures modify the boundary plasma. In addition the intensity ratio Dβ/Dα is not simply a function of plasma temperature but has clear target temperature dependence.
