duality n.两重性；二元性 (1) 对许多人来说，这种双重身份正是产生焦虑的原因。(2) 使用价值的两重性指的是有用性和稀少性。(3) 它也是在它最有效率的层面的一个二元性的例子。 If there are two sides to a coin, metaphorically speaking, there's a duality. Peace and war, love and hate, up and down, and black and white are dualities. Another term for a duality is a dichotomy. Duality has technical meanings in geometry and physics. In geometry, duality refers to how points and planes have interchangeable roles in projective geometry. In physics, duality is the property of matter and electromagnetic radiation to be understood best through wave theory or particle theory.
