sufficiency condition

As to the farmer network model, its stability and attractability of equilibriums are studied using Lyapunov function and the sufficiency condition is deduced.

对于Farmer网络模型，用Lyapunov稳定性理论研究其稳定性，得出其正平衡点稳定及吸引的充分条件。

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。
