对描述一般震源的矩张量的回顾表明，二阶矩张量可以与更简单的震源描述有关，如膨胀中心和双偶。回顾文献之后，详细的代数展开式的矩张量成各向同性和偏分量。在附录中提供了用于测试矩张量分解算法的具体数值示例。
A review of a moment tensor for describing a general seismic point source is presented to show a second order moment tensor can be related to simpler seismic source descriptions such as centers of expansion and double couples. A review of literature is followed by detailed algebraic expansions of the moment tensor into isotropic and deviatoric components. Specific numerical examples are provided in the appendices for use in testing algorithms for moment tensor decomposition.
