研究了超对称冷暗物质（CDM）粒子直接探测中的调制效应。考虑到核形状因子效应和探测器能量阈值，考虑了各种核目标（轻、中、重）。结果表明，核形状因子会使总事件率的调制效应降低到典型值5%以下。尽管如此，在相空间的某些子区域，调制效应可以变得更大，为$hl~25%。在能量传递的某些领域，它在差分事件率中也变得更加明显。这些影响可能被用来歧视背景。
The modulation effect in the direct detection of supersymmetric cold dark matter (CDM) particles is investigated. A variety of nuclear targets (light, intermediate and heavy) are considered, taking into account the nuclear form factor effects and detector energy thresholds. It is shown that the nuclear form factor tends to decrease the modulation effect in the total event rate below its typical value of 5%. In spite of this, however, in some subregions of phase space, the modulation effect can become much larger, $hl~25%.$ It also becomes more pronounced in the differential event rate in some domains of the energy transfer. These effects may be exploited to discriminate against background.
