基于Havriliak-Negami模型的黏弹性材料吸声性能优化被引量:1
《合成橡胶工业》2021年第6期438-442,共5页杨婉雨 尹铫 白国锋 
通过构建Havriliak-Negami模型并使用分层介质模型对黏弹性材料的动态力学参数进行优化,以提升其低频吸声性能。研究结果表明,在频率为1~6 kHz内、厚1 cm钢背衬条件下,厚5 cm橡胶材料的复杨氏模量优化后可实现平均吸声系数达到0.90。同...

6-39 Design of NEG Coating Equipment for Dipole Vacuum Chamber
《IMP & HIRFL Annual Report》2014年第1期294-295,共2页Cheng Jinze Meng Jun Ma Xiangli Hu Zhenjun 
A novel technique is developed to turn the gas-load of the slender vacuum pipes into NEG (non-evaporationgetters) pump[1]. In the technique, the NEG films are grown by DC (Direct-Current) reactive magnetron sputtering...
