【摘要】：隋朝歷爭中,張胄玄和袁充先后提出"日長影短"一說,文章指出這一說法是將一年中影長與白晝長度的周年變化,移植為不同年份相同日的影長與白晝長度發(fā)生變化,而此變化實際并不存在;并剖析了隋開皇年間影長的測量數(shù)據(jù),指出冬至影長分別測自洛陽和長安地區(qū),夏至影長測自長安地區(qū),由于隋朝都城遷址導(dǎo)致長安地區(qū)測影點向南遷移,其相應(yīng)的冬至、夏至影長也隨之變短。這一說法回避了這些事實,被當(dāng)作吉兆為隋朝政治所接受,但遭到了后世的批駁。
[Abstract]:In the Sui Dynasty, Zhang Zhou and Yuan Chong put forward the theory of "short shadow of the sun" successively. The article points out that the annual variation of the length of the film and the length of the day in a year is transplanted into the change of the length of the shadow and the length of the day of the same day in different years. However, this change does not actually exist, and the measured data of the shadow length of Sui Dynasty are analyzed, and it is pointed out that the Winter Solstice shadow length is measured from Luoyang and Changan area, and the Summer Solstice shadow length from Changan area. Due to the relocation of the capital of the Sui Dynasty, the shadow points of Changan area moved southward, and the corresponding the Winter Solstice and the Summer Solstice shadow lengths became shorter. This theory evaded these facts and was accepted by Sui-dynasty politics as auspicious, but was refuted by later generations.
