用感光迹线检查暗筒式日照计构造和安装误差

Method for Inspecting Errors in Structure and Installment of Dark-Tube Sunshine Recorder by Sunlight Line

根据暗筒式日照计构造特点和工作原理,较系统地介绍了利用感光迹线检查日照计构造和安装上存在误差的方法,弥补了先前部分学者提出的关于暗筒式日照计安装误差检查方法存在的不全面、不准确的缺陷。并从几何、成像原理加以论证,证明了利用感光迹线检查暗筒式日照计方位、水平、纬度安装正确与否,隔光板构造是否精确是可行的。

According to the structure and working principles of the dark-tube sunshine recorder, an introduction is made systematically to the method for inspecting the structure and installment errors of sunshine recorders by using sunlight path. It covers the shortages of the original methods in exhaustivity and accuracy. It is feasible to inspect the azimuth, level and latitude of the dark-tube sunshine recorder, as well as to inspect whether the installation is appropriate and the structure of the light screen is reasonable by using the sunlight-path method.
