对化在泉三十法
一、甲子年：天干为甲，地支为子（即地甲子）。因此，天干甲与地支己相合。在甲与己之间，中运为土运。此时，地支见己卯，阳明燥金对化在泉，即金气对冲对位。故卯属震卦，其数为三；己属土，其数为五。三与五合成八。在交节入地之时的前八刻，金气进入地下。从己到卯，向左迁移五位。到地后五日，金气才开始主治大地。燥气行于地面，辛味之物于是生长。三天后，运气与下间之气相同，物候也相同而生。
二、丙子年：天干为丙，地支为子（即地甲子）。因此，天干丙与地支辛相合。在丙与辛之间，中运为水运。此时，地支见辛卯，阳明燥金对化在泉，即金气对冲对位。故卯属震卦，其数为三；辛属水运，其数为一。一与三合成四。在交节入地之时的前四刻，金气进入地下。从辛到卯，向左迁移八位。到地后八日，金气才开始主治大地。燥气行于地面，辛味之物于是生长。三天后，运气与下间之气相同，物候也相同而生。
