对决定非线性自旋弛豫过程时间演化的基本方程给出了严格解。利用自旋相干表示将原算子方程转化为用球谐波展开的概率密度的fokker - planck型c数方程。然后膨胀系数完全以连分式的形式确定。计算相关的平均值，如矩和累积量。
A rigorous solution is found for a basic equation which determines the time evolution of the nonlinear spin relaxation process. Spin coherent representation is used to transform an original operator equation into a Fokker-Planck-type c -number equation for the probability density which is expanded in terms of spherical harmonics. Then the expansion coefficients are completely determined in the form of a continued fraction. Relevant averages such as moments and cumulants are calculated.
