针对中心热斑点火和热核传播燃烧（简称中心点火）的高增益靶设计理论要求很高和技术上的难度很大，我们通过阻热层的设计，在高增益靶的整体点火和燃烧（简称体点火）设计上首先实现挡光系统的非稳定温度脱离，由平衡点火和燃烧逐步过渡到非平衡点火和燃烧，从而将驱动能量降到１５ＭＪ左右，实现了体点火和体燃烧，并达到了可观的增益 The theory of high gain target design for central hot spot ignition and thermonuclear propagation combustion (referred to as central ignition) is very demanding and technically challenging. We designed the thermal barrier to ignite and burn the entire high gain target Referred to as the body ignition) designed to achieve the first non-stable temperature light blocking system from the balance of ignition and combustion gradually transition to non-equilibrium ignition and combustion, which will drive energy down to about 15MJ, to achieve body ignition and body combustion and achieve A considerable gain
