“故其战胜不复,而应形于无穷”,这句话出自《孙子兵法·虚实篇》。意思是:“每次战胜敌人的方法都不重复,而是适应形势作无穷的变化。”的确,这是作战的一个普遍规律。曹操对此说:“不重复动而应之也。”杜牧说:“敌每有形,我则始能随而应之取胜。”(见《孙子十家注》) “Therefore, its victory no longer, but should be shaped in the infinite,” the phrase from “Art of War actuals chapter.” The meaning is: “Each time the method of defeating the enemy is not repeated, but to adapt to endless changes in the situation.” Indeed, this is a common law of war. Cao Cao said: “Do not repeat the move should be also.” Du Mu said: “The enemy every physical, I then should be able to win.” (See “Sun Zi Shi Jia Zhu”)
