A tritium breeding ratio of 1.158 was obtained for a 2 ∶ 1 Be and Li_4SiO_4 volume ratio in the front part which satisfies the tritium self-sufficiency condition for the fusion reactor .

因此，采用Be和Li4SiO4夹层布置，在几何上逼近最优体积比，选择前端Be和Li4SiO4体积比为2时， 氚增殖 率达到1.158，能够较好地满足聚变运行的氚自持条件。

The homogeneous model results show that the tritium breeding ratio would reach 1.20 for Be and Li_4SiO_4 volume ratios from 2 to 6 . A realistic sandwich-type design of the Be and Li_4SiO_4 loadings was used for a geometric approximation of the optimized volume ratio .

根据均匀混和模型的结果，在Be和Li4SiO4的体积比为2至6之间， 氚增殖 率最大可达1.20。

The main concern of the study has been the assessment of the spacial distribution of the tritium breeding ratio the plutonium breeding ratio and the power density in multi-dimensional configuration and the comparison between One - two - three - dimensional global calculation .

重点分析了多维几何中 造 氚 率、造钚率及功率密度的空间分布，比较了一维、二维和三维积分量的计算结果。

Results show that the proposed TBM concept has the advantages of higher tritium breeding ratio ( TBR ) simple structure design and engineering feasibility .
