SAA电源进是指通过SAA标准认可，取得SAA证书而且在澳洲本土相关官网上登录，且可以查验到，才可以进入澳大利亚和新西兰市场，准予销售，流通的电源。
澳大利亚的标准机构为Standards Association of Australian，所以很多朋友把澳大利亚认证称为SAA认证。实际上SAA只是标准制定机构，而不颁发产品认证证书。SAA后来又改名为:Standards Australia Limited。SAA是独立的公司，与政府没有直接的关系，但是联邦政府和州政府是它其中的成员。SAA和澳大利亚联邦政府签署了一个备忘录，承认SAA是澳大利亚的非政府标准组织的最高组织。备忘录也指出，标准的制定要与WTO的要求一致。因此，有协议指出当合适的国际标准已存在时，就不用制定新的澳大利亚标准。澳大利亚的标准以"AS"开头，澳大利亚与新西兰的联合标准以"AS/NZS"开头。澳大利亚的标准与新西兰的标准基本与IEC一致，同时存在一些国家差异。澳大利亚和新西兰推行标准的统一和认证的相互认可，产品只要取得一个国家的认证后就可在另外一个国家销售。

EPS应急电源 简介 我公司生产的 EPS应急电源是根据消防设施、 应急照明、事故照明等一级负荷供 电设备需要而设计生产。 产品由互投装置、 自动充电机、 逆变电源及蓄电池组等 组成。在交流电网正常时经过互投装置给重要负载供电。 当交流电网断电后， 互 投装置将会立即投切至逆变电源供电。 当电网电压恢复时， 应急电源又将恢复为 电网供电。 应急电源在停电时， 能在不同场合为各种用电设备供电。 它适用范围广、 负载适 应性强、安装方便、效率高。采用集中供电的应急电源可克服其他供电方式的诸 多缺点。减少不必要的电能浪费。在应急事故、照明等用电场所，它与转换效率 较低且长期连续运行的 UPS不间断电源相比较，具有更高的性能价格比。 一、YJ单相系列（消防）应急照明电源 1、产品概述 产品用途：适用于建筑物发生火情或其他紧急情况下为应急照明等各种灯具 （含 单进单出型金属卤素灯、钠灯）提供集中供电
重型再生障碍性贫血
severe aplastic anemia，SAA，即重型再生障碍性贫血。
人血清淀粉样蛋白A
serum amyloid A protein (SAA)
SAA和CRP是病毒和细菌感染的标志物，细菌感染时二者浓度升高相平行，病毒感染时，SAA在康复期消失更快。不论CRP是否升高，SAA似乎是急性病毒感染炎症的临床有用标志物。
SAA在结核、麻风、类风关、恶性肿瘤、自身免疫疾病、病毒感染、肾移植排斥、淀粉样病变中均能升高。急性病毒感染时，CRP不像细菌感染时显著升高，它仅在一个狭窄范围内变化，临床需要敏感的病毒感染标志物。
SAA来自于载脂蛋白Apolipoprotein家族,是复合到HDL上的急性相蛋白.含数组、分子量约11-12kDa的蛋白. 人血液中的SAA基本上来自于高密度脂蛋白HDL. 有一组SAA称Constitutive SAA, 也就是SAA3,SAA4和SAA5,在肝脏合成后几乎不进入血流. 另一组急性期SAA, 包括SAA1和SAA2,由肝细胞产生后进入血流.
急性期SAA是人血浆中的主要SAA成份.
巳证明在病毒感染, 肾移植排斥病例中,SAA是一个比其它炎症相关蛋白更有用的标志物.
A-SAA1 and A-SAA2 有93% 氨基酸序列相同，而C-SAA 的多肽长度不同于 A-SAA ，氨基酸序列也仅有55%相同于 A-SAAs. 大部分病毒感染病人康复期SAA<10 mg/L (住院一周后)。2100433B
surface active agent， SAA，即表面活性剂。
不同物质加入水中，其溶液的表面张力会随加入物质的浓度变化而变化。表面活性剂是这样一种物质：当取少量物质溶于水中后，就能引起水溶液表面张力（或液/液界面张力）显著降低，这种物质就是表面活性剂（Surface active agent,SAA）。
