将平均技术应用于由跳变噪声过程驱动的随机磁化动力学。这导致将这种动力学简化为图上的随机磁能动力学。后者最终导致一个连续的主方程，其有效性不基于或受限于Kramers-Brown近似。提出了一种求解主方程的特征值法，并用数值算例进行了说明。
An averaging technique is applied to random magnetization dynamics driven by a jump-noise process. This results in the reduction of this dynamics to stochastic magnetic energy dynamics on graphs. The latter eventually leads to a continuous master equation whose validity is not based on or limited by the Kramers-Brown approximation. An eigenvalue technique for solving this master equation is presented and illustrated by numerical examples.
