2. The resulting locational disarticulation whereby command-and- control functions are carried out in places different from production locations; 以及由此产生的空间分离：指挥、控制功能与生产功能不在同一地点进行；
3. Histogenesis during the early post-operation days of the two types of experiments (amputation & disarticulation)and role of stump tissues with paucity of muscles at that level, are discussed. 对两种手术（截肢和关节断离）后早期组织发生及手术水平的残肢组织和少量肌肉的作用进行了讨论。
