珍珠蚌
英文
margaritana margaritifera-
The results show that the pearls mainly contain aragonites, with some commercially useless pearls having vaterites in addition to aragonites
結果表明，浙江諸暨?三角帆蚌淡水珍珠的礦物組成主要?文石，在無商業價值的部分珍珠中存在六方碳鈣石。Set in its windows, like pearls in an oyster, are an elegant attic red figure krater attributed to a 5th - century bc painter, an etruscan pouring vessel and an array of vases
許多骨董像是蚌殼里的珍珠般被放在櫥窗里，有一尊造型優美的紅色雅典酒器，推測是出自西元前5世紀一位畫家之手，有一個伊特魯里亞人水瓶和一整排的花瓶。Not only then are the smaller, less robust creatures but the pollution in the water changes the color of the nacre and changes the color of the pearl
珠蚌不但更小，生命力更弱，受到污染的水會改變真珠質和珍珠的顏色。3 ) in shell of hyriopsis cumingii ( lea ), the prismatic layers and the nacreous layers are all composed of aragonite minerals, and aragonite crystallites in prismatic layers show obviously preferential orientation of [ 012 ] axis perpendicular to the shell layers, so it is considered that the orientation of aragonite crystallites in prismatic layers perhaps play an important role in deciding the orientation of aragonite crystallites in nacre and acts as one of template to resulting the formation of aragonite with [ 012 ] orientation perpendicular to nacreous layers in nacre
3 ）與海水貝殼明顯不同的是，三角帆蚌稜柱層礦物相與珍珠層一樣皆為文石相，同時查明稜柱層中文石晶體具[ 012 ]軸垂直殼層面的明顯的擇優取向。本文認為，三角帆蚌稜柱層中文石晶體的擇優取向可能對珍珠層中文石晶體的擇優取向存在模板導向的作用，導致珍珠層[ 012 ]定向的文石晶體的形成。In this paper, the nacre of hyriopsis cumingii ( lea ) which is one of the main freshwater pearl - forming mollusk in china is studied emphatically, as compared with the nacre of three species of saltwater pearl - forming mollusks, pinctada martensii ( dunker ), pinctada maxima ( jameson, and peteria penguin ( roding ). the basic characteristics of nacreous and prismatic layers are understood by powder x - ray diffraction analysis, trace elements analysis, amino acid composition of protein and differential thermal analysis
本文以我國主要育珠蚌淡水三角帆蚌貝殼珍珠層為重點研究對象，以三種海水育珠貝馬氏珍珠貝、企鵝珍珠貝及大珠母貝貝殼珍珠層為對比研究對象，首先通過粉末x -射線衍射、微量元素分析、蛋白質氨基酸分析及差熱分析對珍珠層及其與之密切共生的稜柱層的基本特徵進行了初步研究。In conclusion, the freshwater cultured pearls produced by mussel hyriopsis cumingii contain no calcites, and this is obviously different from characteristics of saltwater cultured pearls
三角，帆蚌淡水養殖珍珠中不存在方解石，這與海水養殖珍珠中存在方解石明顯不同。2 ) the carotenoids successfully probed in nacre by in situ resonance raman spectra, are considered one of the most important factors responsible for the coloration of nacre and pearl
2 ）採用共振拉曼光譜首次成功地原位探測到三角帆蚌及馬氏珍珠貝珍珠層中類胡蘿卜素的存在，並提出類胡蘿卜素是珍珠層致色的重要原因之一。Powder x - ray diffraction analysis and micro - raman spectra were used to study the mineral composition of chinese freshwater cultured pearls from zhuji, zhejiang province
摘要採用粉末x射線衍射分析及顯微激光拉曼光譜對三角帆蚌養殖珍珠的礦物組成進行了研究。Sometime the sand felt the freshwater mussel moved and opened, what came in his sight was sea face, sun light, boats and human, human looked him in delight sight, he looked around himself, knowing himself become a pearl
某個時刻砂粒忽然覺得蚌有一點搖動，不久蚌殼張開了，映入眼簾的是海面，陽光，船和人類，人類用欣喜若狂的眼神望著他，他環視一下自身，知道自己已經變成了珍珠。Main conclusions of this work are drawn as follows : 1 ) in nacre of hyriopsis cumingii ( lea ) shell, the aragonite crystallites exist two kinds of orientation, one. which is generally accepted, is the c axis of aragonite perpendicular to nacreous layers, the second, which is proposed in this paper, is the [ 012 ] axis of aragonite perpendicular to nacreous layers
本文所獲得的主要成果有： 1 ）明確提出三角帆蚌珍珠層中文石晶體的擇優取向除了存在公認的其c軸垂直珍珠層面外，還存在其[ 012 ]軸垂直珍珠層面的新取向。分享友人
