Degradation of ultra-high-performance concrete and reinforced concrete under coupled effect of subway stray current and chloride-rich groundwater

Hui Huang, Qiwu Tang, Jianmei Liu, Hai Guo et autres

The degradation behaviour of ultra-high-performance concrete (UHPC) and conventional reinforced concrete (RC) under accelerated stray-current corrosion was investigated. Cube and prism specimens, both plain and reinforced, were subjected to direct current to simulate the subway stray-current environment. The evolution of current, cumulative …

Theoretical and Experimental Study on Mode Power Ratio Diagnosis of Dual-Mode Relativistic Backward Wave Oscillator

Shaohui Han, Renzhen Xiao, Kun Chen, Xiangguo Wu et autres

Hybrid mode converters (MCs) are critical components in high-power microwave (HPM) systems, particularly for devices operating at dual-mode or multimode regimes. Their conversion efficiency, however, may be significantly affected by different power ratios and relative phase differences of the constituent modes. Therefore, …
