| 摘 要： | 文章从光电式数字日照计测量日照时数的原理出发,分析了其安装不水平及未对准南北线、纬度所产生的太阳直接辐照度测量误差。日照时数是以直接辐照度≥120 W/m2作为有日照标准,因此,因安装不规范产生的测量误差仅在直接辐照度接近120 W/m2时会影响日照时数的计算。

| Abstract: | Based on the principle of measuring sunshine duration by photoelectric digital sunshine recorder,the error of solar direct irradiation caused by un-horizontal installation,and misaligned of south-north line and latitude is analyzed in this paper.The direct irradiance≥120 W/m-2 is used as the criterion for sunshine duration.Therefore,the error caused by improper installation affects the calculation of sunshine duration only when the direct irradiance is close to 120 W/m-2. |
