免费标准网(www.freebz.net)GB/T17683.1-1999前台本标准等效采用国际标准ISO9845-1:1992(E)《太阳能在地面不同接收条件下的太阳光谱辐照度标准第1部分:大气质量1.5的法向直接日射辐照度和半球向日射辐照度》本标准提供了国际规定气象条件下的太阳光谱辐照度标准数据，有利于我国辐射数据与国际接轨这些数据适合我国大部分地区，可作为评价各地区太阳光谱辐照度数据的基准。此外，本标准还规定了两种利用太阳光谱辐照度数据表计算器件光谱响应特性加权平均值的方法:纵坐标加权法[波长(横坐标)划分法〕和纵坐标选择法仁能量(纵坐标)等分法口。我国现已颁布实施的标准GB/T6495.3-1996《光伏器件第3部分:地面用光伏器件的测量原理及标准光谱辐照度数据》是专门适用于太阳电池等光伏器件的，数据表格排列完全采用波长划分法;本标准数据表格则不仅包括波长(横坐标)划分法排列(见表1)，而且还包括能量(纵坐标)等分法排列(见表2、表3)。这不仅适用于光伏器件的精确计算，而且还适用于太阳能热利用领域对材料、部件和系统光谱响应特性的简化计算。因此，本标准包含的太阳光谱数据种类更多，能够满足更广泛的需要，属于通用型标准。ISO9845-1:1992(E)中的个别概念、术语和数据与ASTME891:1987,ASTME892:1987以及我国有关的技术文献不一致:有些格式不符合我国GB/T1.1-1993的规定:个别符号在同一标准内不一致。为此，本标准均已做了适当修改，计算机验算数据结果进行了不同的标注，详见正文中的“采用说明”。本标准的附录A、附录B、附录C和附录D都是提示的附录本标准由中国标准化与信息分类编码研究所提出并归口。本标准起草单位:中国标准化与信息分类编码研究所、中国计量科学研究院、中国气象科学研究院本标准主要起草人:王炳忠、张建民、王黛、赵跃进。免费标准网(www.freebz.net)无需注册即可下载

免费标准网(www.freebz.net)GB/T17683.1一1999引言在太阳能热系统性能、光伏系统性能、材料研究、生物研究和太阳模拟领域中，地面上太阳能的吸收比、反射比和透射比是重要的参数。这些光学性质通常是波长的函数，只有先知道太阳辐射通量的光谱分布，才能计算太阳辐射的加权性质。为了比较相互竟争产品的性能，需要有一个太阳光谱辐照度分布的参考标准。本标准的表格提供了地面太阳光谱辐照度数据。根据ASTME891:1987《大气质量1.5的地面法向直射太阳光谱辐照度标准数据表》和ASTME892:1987《大气质量1.5的37。倾斜表面上的地面太阳光谱辐照度标准数据表》中选定的条件，这些模拟数据构成了在不同接收条件下(如不同反照率、倾角等)太阳光谱辐照度的一系列标准的首要项目。本标准表格中所包含的数据是利用以Neckel(内凯尔)和Labs(莱布斯)["[所修正的地球外光谱为基础的零大气质量太阳光谱,BRITS["[[:[MonteCarl.(蒙特卡洛)辐射传输程序和含有乡村气溶胶.7[>7[s7的1962年美国标准大气[51计算导出的模拟数据，详细情况参见附录A.用于形成本标准地面光谱的地球外光谱是由Frohlich费罗里希)和Wehrli(威尔利户I提供的，它是一种被修正和扩展过的Neckel和Labs光谱二z7。正如Frohlich[9〕报告中引证Hardorp(哈道普)[o]的研究那样，Neckel和Labs使用较新的太阳临边昏暗数据修改了他们的光谱，把辐亮度换算成了辐照度。Frohlich将其与在MannaLoa,Hawaii(夏威夷曼纽瓦洛)[m」校准的太阳光度计的数据进行了比较，结果表明这种新的地球外光谱是当前最实用的光谱之一。本标准地面太阳光谱数据的研究是以Bird(伯德)等U"][n〕所报告的工作为基础的。在利用BRITEMonteCarlo辐射传输程序计算地面上的数值时，上述作者仅仅迭代计算到2.4500pm运用ASTME891:1987和ASTME892:1987的16个E,值，使该光谱扩展到4.045Opm.ASTME891:1987中的辐照度值就是根据上述地球外光谱计算的。追加的数据点被添加到太阳光谱辐照度的相应区域，该区域占0.3050pm-4.0450pro之间全辐照度的大约1.5%0本标准待续的部分将会考虑基本数据的最新修改和达到更高准确度的模拟技术。免费标准网(www.freebz.net)无需注册即可下载
