两种答案 供你选择 建议用一
一、Abstract:Uses the gem microscope,the polarizing microscope and the conventional gem appraisal instrument,the infrared spectrum,X fluorescence spectrum,the grating spectrum analysis,carries on the gemology characteristic to the cutin coral the preliminary study.The result indicated:Cutin coral nearly for pure organic matter ingredient composition,its principal constituent for the iodine (I) element,accessory constituent for chlorine (Cl),bromine (Br),barium (Ba),sulfur (S) element.Through actual,obtains concerns its aspect and so on physics,optics,chemistry characteristics.Studied through the polarizing microscope,discussed its growth mechanism and the laminated structure origin,also has discussed this coral infrared spectrum characteristic.Key word:Cutin gold coral,black coral,internal and external characteristic,gemology characteristic,chemical element characteristic.
二、Abstract:The gem microscope,polarized light microscopy and conventional gem identification equipment,infrared spectroscopy,X fluorescence spectroscopy,grating spectral analysis,the horny-coral gem features for the preliminary study.The results showed that:horny corals of almost pure composition of organic matter,and its main components for iodine (I) elements,a secondary component for chlorine (Cl),bromine (Br),barium (Ba),sulfur (S) elements.Through the measured,to obtain their physical,optical and chemical characteristics of such areas.Through polarized light microscopy studies,discussed the growth mechanism and its layered structure of the causes,but also explore the coral reef of the infrared spectral characteristics

1.不要松动所有固定螺丝（物台制动螺丝除外）.
　　2.下偏光镜易脱落,不要经常旋转.
　　3.放置薄片前先稍微下降物台,盖玻片朝上,不要碰 到物镜.移动薄片时不要给物台施加压力.
　　4.不要将薄片放在其他物品上,以免拖动摔坏.显微镜使用、 显微镜使用、保养注意事项
　　5.更换物镜时,旋转物镜转盘,不要扳动物镜.
　　6.使用上偏光镜、试板、勃氏镜时要轻拉轻送.
　　7.长时间停用显微镜,要关闭镜座上的电源开关,或将亮度调到最小.
