我们总结了标准模型的最小超对称扩展中中性和带电希格斯玻色子的主要衰变模式。虽然二体衰变一般占主导地位，但如果涉及顶夸克，W/Z玻色子或重标量玻色子，则重标量，赝标量和带电希格斯玻色子的三体衰变的分支比可以大到阈值以下。分析表达式已被导出的部分衰变宽度和这些衰变模式的物理含义进行了讨论。
We summarize the dominant decay modes of the neutral and charged Higgs bosons in the Minimal Supersymmetric extension of the Standard Model. While two-body decays are in general dominating, the branching ratios for three-body decays of the heavy scalar, pseudoscalar and charged Higgs bosons can be large below the thresholds if top quarks, W/Z bosons or heavy scalar bosons are involved. Analytical expressions have been derived for the partial decay widths and the physical implications of these decay modes are discussed.
