  1. We can be conveniently studied with reference to a crystal of calcite or iceland spar.

    我們可以很方便地以方解石或冰洲石晶體來進行研究。
  2. The calcite popular name has the big calcite and the small calcite two kinds, namely cleaves completely and incompletely two kinds, in big calcite has the transparency is very high, quality excellent is the iceland spar

    方解石俗稱有大方解石及小方解石兩種，即解理完全及不完全兩種，其中大方解石中有的透明度很高，質量上乘的的即為冰洲石。
  3. The courses of the enhancement do n ' t damage iceland spar or change its physical properties, such as birefringence index, optic chatacter. these show that the samples measure up to their industrial standards after the heating. the experiment is successful

    褪色后的冰洲石晶體外觀完好，其雙折率、偏光性等物理性質沒有明顯變化，完全符合它在工業上應用的要求，冰洲石的顏色改善取得了明顯的效果。
  4. The experiments show that the color of the iceland spar can be changed when heated to a certain temperature, that is, light yellow iceland spars will fade when heated to 360 - 370, while dark yellow iceland spar will fade at 440 - 450, brownish yellow iceland spar at 460 - 470 ; and the color of light purple iceland spar can be removed when heated to 390 - 400, while the color of deep purple iceland spar can be removed at 440 - 450, deep reddish purple iceland spar at 460 - 470. on base of the u - v absorption spectrum, we find that the u - v absorption spectra of the faded iceland spars are paralleled to the x axis, the transmittance of them are also greatly improved

    實驗表明，冰洲石在加熱到一定溫度時顏色會發生變化：淺黃色、深黃色和褐黃色冰洲石分別在360 - 370 、 440 - 450和460 - 470完全褪色；淺紫色、深紫色和深紫紅色冰洲石分別在370 - 380 、 440 - 450和460 - 470時完全褪色。通過對褪色后冰洲石進行紫外-可見光吸收光譜測試表明：完全褪色后的冰洲石在紫外-可見光的吸收光譜上表現為一條近平行x軸的直線；紫外、可見光區的紫區的光透過率有了很大了提高。
