由于对抗蚀性能的要求愈来愈高,环保部门的规定又愈来愈严,可供选择的磷化后处理也就变得越来越复杂了。本文阐述了各种可供选用的后处理药剂,总结了含铬和无铬后处理的优缺点,以及它们用于设计新设备或改造现有的设备时的效果,同时还... 由于对抗蚀性能的要求愈来愈高,环保部门的规定又愈来愈严,可供选择的磷化后处理也就变得越来越复杂了。本文阐述了各种可供选用的后处理药剂,总结了含铬和无铬后处理的优缺点,以及它们用于设计新设备或改造现有的设备时的效果,同时还讨论了影响后处理选择的其它因素,最后讨论了在金属基体、前处理工艺和涂料都得到改进情况下采用后处理的相对重要性。 展开更多

Today’s workforce environments are steadily becoming more distributed across the globe,calling for improved ways of facilitating collaborations at a distance,including geo-collaborations or collaborations at critical locations.Newer technology is allowing distributed teams to move away from traditional conference rooms,taking collaborations into the field and giving remote teams more information about the environment.This idea of situating a remote collaborator’s experiences in the field,virtually,promises to enhance the understanding of geographically remote spaces.Newer technologies in virtual reality(VR)hold promise for providing mobile spatial experiences in real-time,without being tied to fixed hardware,such as systems in conference rooms.An exploratory study using VR technology on remote user experiences in a collaboration was conducted to identify the added value for remote collaborators.The findings suggest immersive capabilities improve feelings of presence in the remote locations and perceptions of being in the remote location increase feelings of team membership. 展开更多
