为研究金刚线切割(DWS)的多晶钝化发射极背面电池(PERC)的背叠层钝化工艺对太阳电池长波光谱响应的影响,通过时域有限差分(FDTD)软件模拟传统铝背场电池与PERC电池的电场强度分布情况,并从背面膜层的折射率、钝化质量以及电池的电性能方面比较了两种不同的电池.通过研究发现,在多晶PERC太阳电池中采用背叠层钝化工艺后,能够使电池长波光谱响应增强.当硅片背面刻蚀量达到0.13 g,且在碱抛光工艺后SiO2/SiNx:H叠层膜膜厚为200 nm时,电池的反射率达到最大值,尤其是退火温度为700℃时的钝化效

四旋翼无人机的旋翼对机身构成非定常气动干扰,影响整机的动力学特性.针对此问题,采用计算流体动力学(CFD)计算方法,在刚体假设和不可压流假设下获得无人机机身在前飞工况下受力与力矩的非定常变化情况,并进行风洞实验,验证CFD方法的合理性和计算结果的准确性.采用快速傅里叶变换方法,得到机身所受旋翼气动干扰的模态,从而在干扰力和力矩的变化频率与大小方面进行分析.结果表明:机身所受旋翼的气动干扰与旋翼的转速相关,并且可以由一个5阶傅里叶级数较好地拟合;相对于后旋翼,前旋翼对机身的气动干扰更强;经过简化,单1阶模态
In low signal-to-noise ratio(SNR)environments,the traditional radar emitter recognition(RER)method struggles to recognize multiple radar emitter signals in parallel.This paper proposes a multi-label classification and recognition method for multiple radar
