为选择一种能够遮蔽红外与激光的烟幕干扰材料，在烟幕箱中测试了组分配比不同的微米铜粉的红外与10.6μm激光烟幕透过率，当烟幕浓度为1.0 g.m-3时，1~3μm，3~5μm，8~14μm红外的透过率均小于30%，10.6μm激光的透过率小于20%，红光铜粉、青红光铜粉和青光铜粉对红外与10.6μm激光的衰减能力逐渐增强；同时测试了微米铜粉对红外热像仪的干扰效果，浓度为2.0 g.m-3时，青光铜粉能够完全遮蔽红外热像仪。

High dose copper induced decrease ofⅠ,Ⅱ,Ⅳ-2 content and increase ofⅢof spectrin. High dose copper can also decrease SA, PE content and increase SM, PS content.These showed that high dose can induce injury of erythrocyte by changing elementary structure and moity of membrane protein and membrane phospholipid, which may be one of the mechanisms of goat erythrocyte damage induced by high dose copper. 2. High copper caused the decrease of SOD and GSH-PX activity and the increase of MDA content.

高铜能引起红细胞膜收缩蛋白Ⅰ、Ⅱ及区带Ⅳ-2蛋白含量均显著降低，而区带Ⅲ蛋白含量明显增高，红细胞膜唾液酸含量降低，磷脂酰乙醇胺含量降低，神经鞘磷脂和磷脂酰丝氨酸含量升高，表明高铜能够改变红细胞膜蛋白和磷脂等基本结构和组成成分，这可能是高铜致羊红细胞损伤的机制之一。

We report here on the characterization of copper-plated screen-printed electrodes modified by different clay minerals for the same purpose. The results indicated that clay minerals could improve oxidative and reductive currents of copper through the adsorption of copper ion on the surface of clay minerals. Nontronite showed the largest improvement in reductive currents of copper among the three clay minerals studied.
