摘要本文從光折變晶體中能得出暗孤子所滿足的演化方程出發,用粒子分析力法得出了兩暗孤子相互作用時,其質心間的距離所滿足的演化方程,並得出了兩暗孤子相互作用勢函數的表達式,得到其數值解,並得出如下結論:當兩暗孤子間距離= 0時,其相互作用勢函數有最小值,表示在光折變晶體中有穩定的暗孤子對,並且相互作用達到最大;當兩暗孤子距離5時,其相互作用勢函數幾乎為零,表示兩暗孤子間相互作用很弱,幾乎為零。We think that the main contributions of the book is in two aspects : one is the revolution of some concepts such as utility theory, aximatization of game, extended game ; the other is the breaking through in zero - sum two - person games centered on minimax and corporation game centered on characteristic function. this was, in fact, the development and extension of von neumann ' s classic game paper of 1928. our research shows that these contributions were a pure new theoretical creation, rather than an
