摘要
"天门地户"是运气学说的一大理论难题,目前以春分秋分说、冬至夏至说为主要观点,但其中也存在理论缺陷。天文历法是运气学说的说理工具,中国古代天文坐标系和节气的对应是固定的,且不同的天文坐标系与节气的对应关系不同,不可混淆。天门地户所采用的是黄道坐标系,运气理论形成时期的天文历法明确显示,天门地户对应的是立春、立秋两个节气,这对运气学说的学习及理论研究具有重要的指导意义。
"Gate of Yin and Yang" is a big problem for Motion and Qi Doctrine,the main points are spring equinox and autumn solstice, winter solstice and summer solstice at present, but there are also theoretical aws.Astronomy and calendar are the theoretical tools of Motion and Qi Doctrine. The astronomical coordinate system corresponds to solar terms. "Gate of Yin and Yang" uses the ecliptic coordinate system, and it is spring begins and autumn begins. It has important guiding significance to the study and theory research of Motion and Qi Doctrine.
