【摘要】：元朝郭守敬首创用四丈高表和景符进行测影,以推算冬至时刻,所得到的冬至时刻具有很高的精度。本文通过模拟测量的方法,对郭守敬圭表测影定冬至时刻的方法及其精度进行探究。利用北京古观象台的圭表进行模拟测量,并以古法推定了2014年的冬至时刻,与郭守敬在至元年间(1277—1280)的测定相比较。对郭守敬测定的冬至时刻与模拟测量推算的冬至时刻进行分析,探讨郭守敬所推得的冬至时刻精准的原因以及"授时历议"中所载测影数据的取舍问题。
[Abstract]:Guo Shoujing of the Yuan Dynasty first used the four Zhang height table and the scene symbol to measure the shadow, in order to calculate the Winter Solstice time, the the Winter Solstice moment obtained has the very high precision. This paper probes into the method and precision of Guo Shoujing Gui's measuring shadow and determining the Winter Solstice's moment. Using the Gui Meter of the Beijing Ancient Observatory to carry out the simulation survey, and deducing from the ancient method the the Winter Solstice moment in 2014, Compared with Guo Shoujing's measurements in the Yuan Dynasty (1277-1280), the the Winter Solstice moment of Guo Shoujing's measurement and the the Winter Solstice moment calculated by simulated measurement were analyzed. This paper probes into the reasons for the accuracy of the Winter Solstice and the selection and selection of the shadow data contained in the History of time Teaching by Guo Shoujing.
