There are two sides to every question.

Work-energy theorem and law of conservation of mechanical energy in the two-body problem are given and their applications are discussed.

给出两体问题中的功能原理及机械能守恒定律，并阐述了它们的应

A novel quantum synchronous communication protocol was proposed to resolve the two-army problem effectively by employing the non-locality of Einstein-Podolsky-Rosen(EPR) correlation pairs and quantum teleportation in quantum information in order to establish a trusted channel through distrusted one.

基于量子信息中的EPR(Einstein-Podolsky-Rosen)关联对2个粒子之间的关联性和量子隐形传态技术,通过不可靠信道建立可靠的信道,设计了一个量子同步通信协议,有效地解决了两军问题。
