棱柱层 meaning in English
prismatic layer
Examples
- 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 )与海水贝壳明显不同的是，三角帆蚌棱柱层矿物相与珍珠层一样皆为文石相，同时查明棱柱层中文石晶体具[ 012 ]轴垂直壳层面的明显的择优取向。本文认为，三角帆蚌棱柱层中文石晶体的择优取向可能对珍珠层中文石晶体的择优取向存在模板导向的作用，导致珍珠层[ 012 ]定向的文石晶体的形成。 - 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
本文以我国主要育珠蚌淡水三角帆蚌贝壳珍珠层为重点研究对象，以三种海水育珠贝马氏珍珠贝、企鹅珍珠贝及大珠母贝贝壳珍珠层为对比研究对象，首先通过粉末x -射线衍射、微量元素分析、蛋白质氨基酸分析及差热分析对珍珠层及其与之密切共生的棱柱层的基本特征进行了初步研究。
