前言：
由于三體運(yùn)動(dòng)（主要地球脖隶、太陽、月球）無法準(zhǔn)確預(yù)測暇检，目前二十四節(jié)氣依然還是靠天文臺(tái)觀測产阱，Yovey使用傳說中[Y*D+C]-L方法實(shí)際有很多天數(shù)不準(zhǔn)，def getSolarTerms(_date)12個(gè)if嵌套判斷讓代碼變得十分冗余块仆，由簡書網(wǎng)友“大咖_247c”首先發(fā)現(xiàn)計(jì)算不準(zhǔn)問題……

1构蹬、在校驗(yàn)過數(shù)據(jù)與公式差異后，第一方案是采用15%黃經(jīng)夾角計(jì)算悔据，計(jì)算后差異依然存在庄敛，地球橢圓形軌道一年內(nèi)公轉(zhuǎn)速度差異超過7%；

2科汗、在發(fā)現(xiàn)橢圓軌道問題后藻烤，嘗試使用平均值、開普勒第二定律計(jì)算行星軌道头滔，計(jì)算值已經(jīng)十分貼近了怖亭，但依然和香港天文臺(tái)數(shù)據(jù)有差異，恍然大悟拙毫，地球依许、月亮、太陽三個(gè)天體呈現(xiàn)無法完美預(yù)測的三體運(yùn)動(dòng)缀蹄，甚至還包括木星引力影響（比如傳說中九星連珠峭跳，雖然引力抵消微弱），而且太陽本身也在運(yùn)動(dòng)缺前，地球和太陽的質(zhì)量也不是永恒不變的蛀醉，這就導(dǎo)致地球的恒星年相對(duì)穩(wěn)定，但回歸年浮動(dòng)振蕩衅码；

3拯刁、當(dāng)試過所有技術(shù)物理原理還無法調(diào)節(jié)誤差后，最終使用了Chen Jian的核心設(shè)計(jì)理念逝段，添加了十六進(jìn)制加存二十四節(jié)氣垛玻。（還是要靠香港天文臺(tái)）

跟進(jìn)Chen Jian的設(shè)計(jì)思路，增加了一層向量壓縮奶躯。
因?yàn)?4節(jié)氣每個(gè)月新歷月固定有兩個(gè)帚桩，所以list保持順序，月份就不用存了嘹黔，一定是1账嚎、1、2、2郭蕉、3疼邀、3……
只記錄日期的話，日期數(shù)據(jù)過大召锈，所以對(duì)200年內(nèi)4800個(gè)數(shù)據(jù)進(jìn)行分組比對(duì)旁振，求出最小公約數(shù)，得出最小公約數(shù)年向量[4, 19, 3, 18, 4, 19, 4, 19, 4, 20, 4, 20, 6, 22, 6, 22, 6, 22, 7, 22, 6, 21, 6, 21]烟勋，將爬取數(shù)據(jù)減去這個(gè)最小公約數(shù)向量规求，就得到了一個(gè)元素最大值不大于3的矩陣。
所有數(shù)字不大于3卵惦，兩個(gè)二進(jìn)制就可滿足存儲(chǔ)一個(gè)日期，一個(gè)十六進(jìn)制就能存儲(chǔ)一個(gè)月瓦戚，利用Python3 位移算法 << 2 將原本龐大的txt文本壓縮成長度200的12位16進(jìn)制list沮尿。
