简介：导电塑料ECP产品是由特种导电碳黑和各种聚合物结合的完善产物，它给予各种抗静电产品优异的特性和长久的ESD/EMI功能。产品适合于注射成型（周转箱、零件盒、尽寸精密外壳、部件、EMI屏蔽外壳）、挤出薄片（ESD瓦楞板）、和热成型、管材、型材挤出成型和吹膜等工艺（ICTray及ESD包装箱及ESD包装膜）。

简介：介绍一种快速的并行协议--ECP协议在高速单片机与PC机间通信的应用.高速单片机采用SX52BD,并用虚拟外设实现.

简介：目的探讨PPD反应与发作期哮喘患儿ECP,IgE及细胞因子表达的关系.方法实验分健康对照组和哮喘发作组,均进行结核菌素纯蛋白衍化物(PPD)试验.观察PPD反应与哮喘临床症状、肺通气功能测定、血清ECP、IgE等的关系以及PPD试验后哮喘患儿外周血IFN-γ,IL-4,IL-12P40mRNA的表达.结果哮喘患儿PPD阴性者(24/32例)明显多于阳性者(8/32例),且PPD反应阴性患儿哮喘中/重度发作(16/24例)较PPD阳性患儿(2/8例)多,P<0.05.PPD阴性的哮喘患儿血嗜酸性细胞阳离子蛋白(ECP)及IgE较PPD阳性的哮喘患儿明显增高(P<0.05).哮喘患儿PPD试验后IL-12P40mRNA,IFN-γmRNA无明显变化,而IL-4mRNA升高较对照组明显(P<0.05),致IFN-γ/IL-4mRNA比值下降.结论PPD反应阴性的哮喘患儿可能存在着细胞免疫功能低下.PPD正向免疫刺激作用在哮喘患儿中受到抑制.
