(e-book)역상고성후편에 기술된 달의 운행 > e-book

≪역상고성후편≫에서는 태양의 가감차에 의한 일평균(평행, 원지점, 정교에 모두 영향), 태양과 지구 사이의 거리와 태양과 달의 원지점과의 관계에 의한 이평균, 태양과 달의 승(강)교정 사이의 관계로 인한 삼평균으로 하고, 태양의 위치가 달 궤도의 이심률에 영향을 주기에 이를 고려한 초균수(차각구각법 대신 양삼각법 사용), 지구와 태양까지의 거리와 달과 태양 사이의 각 거리의 영향 때문에 생기는 이균수(변출), 태양부터 달까지 실제 각거리와 태양과 달의 원지점 사이각 거리의 합에 영향을 받는 삼균과 앞의 두 각거리에 영향을 받는 말균으로 하는, 세 가지의 평균과 네 가지의 균수를 설명하고 있다. 이는 뉴턴의 7가지 지질차와 동일하다. 이 값들을 이용하여 승도차를 고려하여 달의 동지점 기준 경도와 이심률의 변화와 이에 따른 황도와 백도의 사이각의 변화를 고려하여 달의 황위를 구한다. 본서에서는 ≪역상고성후편≫의 내용 중에 달의 운행에 대한 원리, 계산법, 표만을 해설한다.
