A new compound (CHZ)(HTNPG).0.5H2O was synthesized by mixing carbohydrazide(CHZ) and trinitrophloroglucinol(TNPG) and characterized by elemental analysis and Fo
Based on the experimental results, in which the fabricated error of the double layer frequency selective surface (FSS) leads to the transmission loss and the re
The external flow field around a certain mining dump truck was simulated. The airflow structure and the aerodynamic drag were discussed, and the relationship be
