Guangtongxin yanjiu, 2013 在UV（紫外光）通信系统中,噪声对信号会产生比较明显的干扰。为了提高系统的通信性能,文章对UV通信系统中的噪声进行了分析。设计了一个模块对噪声进行采样,并分析了PMT（光电倍增管）暗电流噪声、PCB（印制电路板）热噪声、EMI（电磁干扰）噪声以及电源引入的噪声等4种噪声的时域和频域特性,及其对系统性能的影响。为了克服模拟滤波性能不理想的缺点,在接收端采用FPGA（现场可编程门阵列）设计了一个数字滤波器来抑制噪声。实验结果表明,该数字滤波器对SNR（信噪比）有3～7dB的改善。

Characterization of Retained Austenite in Advanced High‐Strength Steel
Scanning, Volume 2023, Issue 1, 2023., 2023 The retained austenite (RA) in advanced high‐strength steels directly affects their plasticity. It is very important for the accurate characterization of their content and types. This paper prepared three specimens with three different Mn contents (1.0%, 1.4%, and 1.7%) that are used to obtain high‐strength steel by ultrafast cooling heat treatment ...
