双轨条件矩阵
H_VIDEO 与 H_MAIN 独立列出必要条件、正向预测、反证条件、替代机制、形成链和协调伪造规模。
| 模型 | 条件类型 | 条件 | 评估 | 关联证据 |
|---|---|---|---|---|
| H_VIDEO | necessary_condition | 须同时成立火源、锅炉、蒸汽压力、机械传动和船体推进；各环节须属永乐时期 | input_limited | |
| H_VIDEO | positive_prediction | 同代技术记录或遗物可展示闭合蒸汽推进链 | input_limited | |
| H_VIDEO | disconfirmer | 来源只谈风帆/季风或未见锅炉、发动机、螺旋桨；“蒸汽”来自现代释读 | input_limited | |
| H_VIDEO | alternative_mechanism | 风帆推进；潮汐/季风；火用于生活或信号 | input_limited | |
| H_VIDEO | formation_chain | 火源→锅炉→蒸汽→动力轴/桨→位移 | input_limited | |
| H_VIDEO | fabrication_or_coordination_scope | none;不把缺口当伪造证据 | input_limited | |
| H_MAINSTREAM | necessary_condition | the specific fleet must possess a boiler, pressure cycle and mechanical drive; the date must precede or match the 1405-1433 voyages; water, fuel, exhaust and control arrangements must be feasible | input_limited | |
| H_MAINSTREAM | positive_prediction | a dated Chinese technical source or object tied to Zheng He ships should reveal steam propulsion and a drive mechanism | input_limited | |
| H_MAINSTREAM | disconfirmer | later practical-steam chronology, normal sail/oar fleet descriptions and no vessel-specific apparatus weaken the claim; lack alone is bounded, not disproof | input_limited | |
| H_MAINSTREAM | alternative_mechanism | sail/oar propulsion; fire for domestic/maintenance work; water-heating metaphor; later retelling | input_limited | |
| H_MAINSTREAM | formation_chain | FC-F5-C02 | input_limited | |
| H_MAINSTREAM | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic |
