SAA电源背景简述

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。

整流后,只有 +电或 -电单独供给的电源,就是单电源。例如: 如果同时用±电一齐供给的电源就是双电源。例如: 运放作为模拟电路的主要器件之一,在供电方式上有单电源和双电源两种,而选择何种供 电方式, 是初学者的困惑之处, 本人也因此做了详细的实验, 在此对这个问题作一些总结。 首先,运放分为单电源运放和双电源运放,在运放的 datasheet 上,如果电源电压 写的是(+ 3V- +30V ) /(±1.5V-± 15V )如 LM324 ,则这个运放就是单电源运放,既 能够单电源供电,也能够双电源供电;如果电源电压是( ±1.5V-± 15V )如 LM741 ,则 这个运放就是双电源运放,仅能采用双电源供电。 但是,在实际应用中,这两种运放都能采用单电源、双电源的供电模式。具体使用 方式如下: 1:在放大直流信号时,如果采用双电源运放,则最好选择正负双电源供电,否则输 入信号幅度较小时

SAA蛋白质

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

SAA活性剂

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)。
