【摘要】

：

不同老化环境(湿热、热水、热氧)对复合材料的性能有着重要的影响。文中分析了同一温度不同老化环境下T800碳纤维/环氧树脂基复合材料的吸湿(湿热、热水)和失重(热氧)特性,并对比了老化前后的表面形貌、物理化学特性、动态力学性能及层间剪切性能。结果表明,在相同温度下,热氧环境下的失重率要大于湿热和热水环境下的吸湿率;随着老化时间延长,热氧环境下材料表面形貌变化相比湿热和热水环境变化较大;在70℃不同老化环境下,热氧环境下材料的玻璃化转变温度变化值要大于湿热和热水环境下的玻璃化转变温度变化值,说明热氧对T800

Robust Solution for Boundary Layer Height Detections with Coherent Doppler Wind Lidar

Although coherent Doppler wind lidar(CDWL)is promising in detecting boundary layer height(BLH),differences between BLH results are observed when different CDWL measurements are used as tracers.Here,a robust solution for BLH detections with CDWL is propose

Controls on the Northward Movement of the ITCZ over the South China Sea in Autumn: A Heavy Rain Case

The autumn Intertropical Convergence Zone(ITCZ)over the South China Sea(SCS)is typically held south of 10°N by prevailing northeasterly and weakening southwesterly winds.However,the ITCZ can move north,resulting in heavy rainfall in the northern SCS(NSCS)
