摘　　要：为了达到最好的居住效果,古人运用长期积累的经验对房屋内部进行装修和改造。对内蒙东部通辽地区哈民忙哈遗址中F33和F50房址地面上的白色铺垫材料进行了分析,发现该遗址地面坚硬以及地面发白的原因是使用了白灰作为地面装饰层;并利用红外光谱峰在吸收强度上的变化,判断碳酸钙中原子无序度的信息,从而判断其制作工艺。结果表明,遗址白色铺垫材料中的方解石ν_(2)/ν_(4)的比值约在5左右,远远高于天然石灰石,反映了天然石灰石与人工制备石灰砂浆中方解石晶体结构无序性的差异,证明该遗址的白灰层是人工烧制而成的,说明我国古代先民在很久之前就开始使用人工烧制的石灰作为装饰建筑的材料。To achieve the best living effect,the ancients used their accumulated experience to decorate and transform the interior of houses.This paper analyzes the white surface of F33 and F50 at the Hamin-Mangha site in Tongliao,eastern Inner Mongolia.It is found that the reason for the hard and white ground of the site is the use of white ash as the ground decoration layer;The change of infrared spectrum peak in absorption intensity is used to judge the information of atomic disorder in calcium carbonate,to judge its manufacturing process.The results show that the ratio of calciteν_(2)/ν_(4)in the white bedding material of the site is about 5,which is much higher than that of natural limestone,which reflects the difference in the disorder of calcite crystal structure between natural limestone and artificially prepared lime mortar.It proves that the white ash layer of the site is artificially fired,indicating that our ancient ancestors began to use artificially fired lime as decorative building materials a long time ago.
