1. Wave Particle Duality: Wave or Particle? 波粒二象性：波还是粒子？
2. To site an example, the famous "wave particle duality", where an object is both a wave and a particle simultaneously). 类似的困难也存在与现代物理学中。举个例子，著名的“波粒二象性”，一个客体同时即是波又是粒子）。
3. The author suggests that it is necessary to design experiments to measure the phase velocity of de Broglie wave and to make a thorough study on the wave-particle duality. 即使自然界存在超光速的物质运动也不可能动摇狭义相对论；建议设计实验测量德布罗意波的相速度并深入研究波粒二象性。
4. The First Displacement Law of Duality Operator is, in fact, referred to the Principle of Duality, which is a universal logic law. 第一移位律实际上指对偶原理，它是一个普遍的逻辑规律；
