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。Akoya, tahitian, and south sea pearls found in jewelery have a tendency to be the roundest, while freshwater pearls can be oval or slightly off - round
因此,在每一珍珠層,都會有部分光線被反射,也有一部分光線被折射,還有一部分光線會穿過珍珠。This effect is created when light reflects off the many layers of tiny calcium carbonate crystals that compose the pearl
珍珠是由一層層厚約0 . 3 0 . 4m的珍珠層組成的。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。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。The research indicates that the microscale spiral ( vortex ) growth dislocation is another important growth mechanism of pteria penguin and blister pearl from sanya, hainan province
通過對該珍珠層的表徵與示蹤,初步證實微尺度螺旋(渦旋)生長位錯是海南三亞企鵝貝及其附殼珍珠又一重要的生長機制。Time passed. layers of the pearl had come off. the sand returned to himself. he felt he was very pure, now he was able to meet his sand
又是一個漫長。珍珠層已經被剝離得沒有了,砂粒又露出了自己的本色,他覺得很乾凈,自己可以一塵不染地去見另一粒砂了。A ceylon legend tells how the tears of adam and eve created a lake that gave birth to pearls - white or pink pearls from eve s tears, and the more precious and rarer gray and black pearls from adam s tears
