At the same blow ratios , the double - layer porous plate exhibits higher cooling effectiveness than single - layer , but the difference of cooling effectiveness between the triple - layer plate and the double - layer plate is not significant 在相同吹风比下,双层层板要比单层层板冷却有效性高,而三层层板与双层层板之间的差别不大。
A triple - layer radar absorbing coatings composed of dielectric and magnetic materials were prepared according to resistance matching principal , which is then further coated with an infrared and visible light camouflage coatings 摘要依据阻抗匹配原理制备了一种3层雷达吸波涂层,并在吸波涂层表面喷涂一定厚度的可见光、红外伪装涂料,比较了喷涂伪装涂料前后涂层吸波性能的变化。
In a word , the two type of voa both have valuable applicability and potential market . the author have done numerous processing to work out new processing such as polymer coating and cure and triple - layer - metal film vaporing . other new processing , polymer ultra - violet ( uv ) cure and inductively - coupled plasma ( icp ) etching were studied 作者经过反复的工艺实验,确定了聚合物波导涂膜和固化、三层金属电极蒸发和腐蚀等新工艺的参数,并得到了聚合物紫外固化、等离子体刻蚀等新工艺的初步数据。
