摘　　要：运用量子力学方法，精确地求出了海气耦合随机－动力模式的依时解．对依时解的分析表明：当气候系统处于基态时，系统的行为呈布朗运动形式，由此从理论上证明了Ｈａｓｓｅｌｍａｎｎ关于随机气候模式建立的立足点．当系统处于第一激发态时，系统运动呈随时间衰减的形式；在一定条件下则为周期振荡，主周期长度为２．３年．最后将结果用来讨论二氧化碳浓度倍增时的气候影响．By utilizing the method of quantum mechanics,a time dependent solution of the coupled air-sea stochastic dynamic model is obtained accurately.The solution reveals that the air-sea system is in a way of Brownian motion if the system is of basic state,herefrom the standpoint of Hasselmann's stochastic climate model is proved theoretically.If the system is of the first excited state,the system is in a way of decay with time or in a way of periodic oscillation with a main period of 2.3 years in certain conditions of the system. Finally,the solution is applied to study the effect of doubling CO2 on the climate.
