【摘要】 由日照记录迹线描述方程,给出标准日照记录迹线,并对日照计安装偏差对日照记录正确性和日照迹线状态改变的影响进行了分析,发现日照计安装偏差造成的记录误差,水平最甚,方位次之,纬度最轻。用日照记录迹线形状来判断日照计安装偏差,纬度不准最易,方位不准次之,水平不准最难。并提出了暗筒式日照计的正确安装方法,确保其水平、方位、纬度误差最小。更多还原

【Abstract】 Based on the sunshine records trace equation,the standard sunshine records trace is given,the correctness of sunshine record and the change of sunshine trace state caused by sunshine recorder installation error have been analyzed. It is found that the errors caused by trace installation of sunshine recorders are affected by evenness mostly,then by azimuth and latitude. To judge the sunshine installation deviation with the help of sunshine records trace(curved) line shape,it is the easiest by latitude,then by azimuth and evenness. Finally,the correct installation method of Jordan sunshine recorder is proposed to ensure the minimum errors by evenness,azimuth and latitude.更多还原
