陈景润猜想跟哥德巴赫猜想和陈景润定理实质不同.用集合A表示陈景润猜想,用集合B表示哥德巴赫猜想,则集合A∪B表示陈景润定理.应用陈景润猜想和哥德巴赫猜想教学现行人教版高二数学教材上的合情推理,可以在直接证明过程中,通过观察、类比、递推、归纳出两个猜想成立的范围,概括成华陈空间,探究华陈空间中使陈景润猜想和哥德巴赫猜想都成立的解数和数学规律,丰富了教学合情推理的内涵. Chen Jingrun’s Conjecture is Different from Goldbach’s Conjecture and Chen Jingrun’s Theorem in Essence. We use the set A to represent the Chen Jingrun’s conjecture, and the set B to represent the Goldbach’s conjecture, then the set A∪B means the Chen Jingrun’s Theorem. In the process of direct proof, through the observation, analogy and recursion, the range of two conjectures can be summed up, which can be summed up into the Hua-Chen space to explore the relationship between Chen Jing-run’s conception and Gothic Bach conjecture has set up the solution of numbers and mathematical rules, enriching the connotation of co-rationality reasoning.
