| 1. | Aragonite and magnesium calcite are more soluble than normal calcite 霰石和镁方解石,比普通方解石更容易溶解。 |
| 2. | The results indicated that vaterite crystals have been induced by vesicle system 结果表明囊泡体系诱导了球霰石晶体的产生。 |
| 3. | Flowers of iron 霰石华铁华 |
| 4. | Spherical vaterite and calcite with various morphologies were produced in the presence of 4 - bapta by simply constant precipitation method 通过简单的直接沉淀合成了球状的球霰石和多种形态的方解石。 |
| 5. | The calcium carbonate in corals or in the shells of other marine creatures comes in two distinct mineral forms : calcite and aragonite 珊瑚或其他海洋生物外壳里的碳酸钙,包含两种完全不同的矿物形式:方解石和霰石。 |
| 6. | They are said to be “ undersaturated . ” shallow , warm surface waters are described as “ supersaturated ” with respect to both calcite and aragonite , meaning that these minerals have no tendency to dissolve 海洋浅层的温暖海水,对方解石和霰石则为过饱和,代表这两种矿物不倾向溶解。 |
| 7. | 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。 |
| 8. | 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。 |
| 9. | 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。 |
