Dianci bileiqi±800kV特高压直流换流站金属回线避雷器（简称：EM避雷器）多次故障分析将原因指向能量耐受性能薄弱电阻片（简称：“矮片”）存在导致的避雷器吸收能量崩溃损坏，为解决EM避雷器故障频发问题，利用PSCAD/EMTDC仿真软件研究系统过电压情况，明确EM避雷器运行中的决定性工况，根据实际需求和设计裕度优化EM避雷器的参数配置和结构型式。参数配置方面，依据过电压计算结果，采用能量吸收和保护水平校验方法，建议提高避雷器的参考电压，增加并联元件数量、提升单片电阻片的能量吸收能力；结构优化方面，采用ATP ...

Guangtongxin yanjiu, 2018 文章利用理论模型研究了GaAs/AlxGa1-xAs量子阱红外探测器（QWIP）中掺杂参数对探测器探测波长的影响,并借助2×2哈密顿方法计算了此模型的特征能态。通过将模拟结果与现有实验数据进行对比、分析可知,当掺杂浓度增加时,峰值归一化吸收率、吸收系数和响应度等呈非线性增大。同时还发现,在AlxGa1-xAs势垒中,Al的摩尔分数（x）增加时,子带间吸收能力增强,但吸收的峰值波长会向较短的波长方向移动,进而判定掺杂浓度是高性能QWIP设计的重要参数之一。
