摘要翻译：
多分散性对势能景观有显著影响；随着多分散性的增加，平均固有结构能随温度的升高而降低。在固定体积分数下，增加多分散性降低了玻璃化转变温度和玻璃形成的脆性，类似于某些聚合物熔体中的抗塑化作用。在低温下观察到一个有趣的与温度有关的非均质性与多分散性的交叉，这是由于在较低的多分散性下动态非均质性的快速建立。

英文摘要：
Polydispersity is found to have a significant effect on the potential energy landscape; the the average inherent structure energy with temperature decreases with polydispersity. Increasing polydispersity at fixed volume fraction decreases the glass transition temperature and the fragility of glass formation analogous to the antiplasticization seen in some polymeric melts. An interesting temperature dependent crossover of heterogeneity with polydispersity is observed at low temperature due to the faster build-up of dynamic heterogeneity at lower polydispersity.
