The effect of the ambient temperature(Ta is 50 ℃ and 18 ℃), surface temperature (Tw is -10.9 ℃, -23.0 ℃, -28.0 ℃) and the irregular surface structure on frost crystal/condense droplet growth characteristic were studied. The densification mechanism of the frost layer was summarized and analyzed. The experimental results showed that the higher the ambient temperature, the lower the surface temperature, and the shorter the frost crystal growth cycle. On the surface of the three specimens, the closer to the edge of the specimen, the earlier the condensation droplets appeared and the faster it grew. Besides, it was also found that the surface morphology and structure have influence on the whole process of droplet condensation and frost layer growth. The mechanism of the surface topography structure on condensation was preliminary analyzed, but the mechanism of irregular surface topography structure on frost growth needs further study.]]> 2024/12/2 0:00:00 ZHANG Nannan, WANG Yuan, YUE Xiaofei 44true <![CDATA[Experimental design for the effect of ablation on the opening process of soft insulator in pulse motor]]> 2024/12/2 0:00:00 BIAN Yunlong, LI Haiyang, SHEN Zhibin, ZHU Hongbing, WANG Zhiqiang 43true <![CDATA[Self-ensemble satellite anomaly detection method for center-constrained contrastive learning]]> F score than that of the state of the art method.

structure under hypervelocity impact]]> t/D) ratio and impact angle θ on the hypervelocity impact characteristics of Ti/Al/Mg impedance gradient structures were studied with AUTODYN finite element software. Results show that the influence of Ti/Mg ratio on the expansion characteristics of the outer bubble fragment cloud is within 5%, but increasing the Ti/Mg ratio can improve the degree of fragmentation of the projectile. The structural energy absorption characteristics are best within the range of 0.625 to 1. The expansion speed of the outer bubble fragment cloud and the mass of the large fragment at the center of the projectile decrease with the increase of t/D ratio, while the unit face density energy absorption decreases. Oblique impact is beneficial to the dissipation of projectile kinetic energy by the impedance gradient structure, but it will reduce the degree of fragmentation of the projectile. After θ exceeds 40° or 50°, the "slip effect" has a significant impact on the impact characteristics of the impedance gradient structure. The perforation area of the impedance gradient structure decreases with the increase of Ti/Mg ratio and t/D ratio, and increases with the increase of θ, and an empirical formula for the dimensionless perforation area of the impedance gradient structure is obtained based on dimensional analysis.]]> 2025/1/20 0:00:00 CHEN Xing, XU Dafu, LIU Zhanfang, WEI Guoning, LU Yonggang 1true
