The gemmological classification and fashioning properties and technological requirements are introduced systematically . the fashioning skills of faceted calcite stone are probed 摘要介绍了方解石的宝石学分类和加工性质及工艺要求，着重探讨了刻面方解石宝石的加工技巧。
Thus , corals and pteropods , which both produce aragonitic shells , and coralline algae , which manufacture magnesium calcite , may be especially susceptible to harm from ocean acidification 珊瑚和翼足类都会分泌霰石外壳，珊瑚藻则制造镁方解石，因此，它们可能特别脆弱，容易受海洋酸化的伤害。
The cementation of laumonite , calcite and chlorite , compact and pressure solution , as well as the dissolution of laumontite , feldspar are also of main factors which affect reservoir properties 方解石、绿泥石、浊沸石的胶结作用、压实压溶作用和浊沸石、长石的溶解作用也是影响储集性能的主要因素。
The influx of carbon dioxide from the atmosphere has caused the saturation horizons for aragonite and calcite to shift closer to the surface by 50 to 200 meters compared with where they were positioned in the 1800s 大气的二氧化碳汇入海中，已经导致方解石和霰石的饱和线往上移动，比1800年代更接近海面50 ~ 200公尺。
Many people consider lapis lazuli to be a stone of truth and friendship . it is said to bring harmony in relationships and facilitate open communication . it is reputed to enhance awareness , insight and intellect 如果含较多的方解石时呈条纹状白色，含黄铁矿时就在蓝底上呈显黄色星点，玻璃光泽和蜡状光泽，条痕浅蓝色，半透明至不透明。
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 方解石俗称有大方解石及小方解石两种，即解理完全及不完全两种，其中大方解石中有的透明度很高，质量上乘的的即为冰洲石。
It was was recognized as a symbol of ability , success and divine favor . many people consider lapis lazuli to be a stone of truth and friendship . it is said to bring harmony in relationships and facilitate open communication 如果含较多的方解石时呈条纹状白色，含黄铁矿时就在蓝底上呈显黄色星点，玻璃光泽和蜡状光泽，条痕浅蓝色，半透明至不透明。
High - latitude calcareous phytoplankton and zooplankton might share a similar fate , although their declines would come decades later because their shells are formed from calcite , the less soluble form of calcium carbonate 高纬地区的钙质浮游植物和浮游动物可能有相似的命运，虽然它们受到影响的时间也许会晚数十年，因为钙质浮游生物的外壳由方解石形成，这种碳酸钙矿物结晶比较不容易溶解。
Researches of more than four decades in the field , especially from the early 1980s on , during which the analysis of the isotopes in fossil brachiopods and early diagenetic cements has contributed much to the knowledge , achieved appreciable progress 40多年的研究结果，尤其是进入80年代方解石质的腕足化石壳体和早期成岩胶结物等特殊样品的应用，取得了若干重大研究进展，但同时也发现了一些新的问题。
Finally , a fouling crystal treated with electromagnetism is compared with that of untreated under an electric microscope . they were found to have different structure . the fouling crystal treated with is less compacted in structure 4 、将经过电磁处理的污垢晶体和未经过电磁处理的污垢晶体在扫描电镜下进行观察和分析，发现电磁抗垢技术的机理是改变了污垢晶体的结构，由致密型的霰石变为松散型的方解石。
