Some of preblems will be accounted by means of stained thin section microscopic identification , catholuminescence microscopic observation , trace elent analysis , carbon and oxgen isotope geochemistry , and fluid inclusion analysis 認(rèn)為利用染色薄片鑒定、陰極發(fā)光顯微鏡觀察、微量元素分析、碳氧穩(wěn)定同位素測定及包裹體測溫等綜合手段進一步研究,最終將解決這些問題。
The results showed that the analysis of isotope could restore the main food component into such type as c3 plants , c4 plants , animals or sea food , furthermore the analysis of trace element could identify the concrete plant or animal 研究結(jié)果表明同位素分析結(jié)果能夠揭示當(dāng)時人的食物到底以c3植物、 c4植物、食草動物、海產(chǎn)資源的哪個為主這一問題,而微量元素分析結(jié)果能夠在同位素分析所分類的大類型中,進一步探討具體的動植物種類。
By analyzed the trace elements of 31 species chinese herbal drugs and applied the veiws of modern biology and medicine , the paper discussed deeply the varieties and content of trace elements and the correlation of different trace elements spectrum in physiology and biochemistry and pharmacologica and drug effect 摘要通過對31種中草藥的微量元素分析,應(yīng)用現(xiàn)代生物學(xué)和現(xiàn)代醫(yī)學(xué)的觀點討論了微量元素的種類、含量以及不同微量元素譜在生理生化、藥理藥效上的相關(guān)性。
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(zhì)氨基酸分析及差熱分析對珍珠層及其與之密切共生的棱柱層的基本特征進行了初步研究。
Based on the analysis of the data of carbon nitrogen isotopes and trace elements such as sr , ba ca et al . of the two pieces of excavated human bones of late period of dawenkou culture and period of chunqiu and zhanguo in upper shu river in shandong province , the research applied the analysis of carbon nitrogen isotope and trace elements into the study of ancient diet 摘要本研究通過對山東沐河上游大汶口文化晚期及春秋戰(zhàn)國時期2塊人骨的碳、氮同位素分析和無機成分的掘、鋇、鈣等微量元素分析,探討了同位素和微量元素分析在古代人類食物結(jié)構(gòu)研究中的應(yīng)用問題。
