Furthermore, permeability of quartz hybrid phenolic materials and pyrolysis temperature meet the formula K=9.5×10-15T-6.32×10-12. The experimental results have enriched the basic physical data of this kind of resin-based composite materials, and provided a basis for the analysis of material permeability and thermal mass diffusion characteristics.]]> 2021/9/29 0:00:00 WANG Liyan, CHEN Weihua, CUI Zhanzhong, WANG Zhenfeng, WANG Yun, JI Bingbing 3true <![CDATA[Mechanochemical effect of 921A steel corrosion in seawater]]> 2021/9/29 9:04:41 WANG Xiangjun, XU Qinglin, SONG Yusu, WANG Haiguang 2true <![CDATA[Simulation analysis of long-range propagation of charged particle beams propelled by moving window]]> 2021/9/29 0:00:00 Hao Jianhong, Wang Xi, Zhang Fang, Zhao Qiang, Xue Bixi, Fan Jieqing, Dong Zhiwei 1true
