This paper researches on the water and suspension in zhujiang ( pearl ) river and her three branches, sampling in makou hydrological gorge station of xijiang river, hekou hydrological gorge station of beijiang river and boluo hydrological gorge station of dongjiang river. the author calculated the riverine carbon flux and measured the content of different carbon forms and carbon isotope composition. furthermore, the author also studied drainage basin erosion and the influence of vegetation distribution on erosion
本文以珠江水體、懸浮物為研究對象，通過對西江馬口、北江河口、東江博羅斷面水體取樣，分析水體中不同形態碳含量，測定碳同位素值，並計算了河流碳通量值；還對珠江流域的侵蝕狀況及植被分佈對流域侵蝕的影響進行了探討。 -
The paper adopts some methods such as gas composition, carbon isotope, systematical analyzing and testing of reservoir bitumen biomarker from high evolutional natural gas and quantitative calculation of mixed gas, illustrates that natural gas from the section of jialingjiang formation is mainly attributed to sapropel type organic matter gas of permian, comes from carbonatite hydrocarbon rocks permian which most of them are overmature, its main gas source has nothing to do with carbonatite hydrocarbon rocks of jialingjiang formation themselves, presents in geochemistry characteristics of oil type cracked gas
摘要通過對川中川南過渡帶西部的磨溪潼南地區嘉二段天然氣組成、碳同位素組成、高演化天然氣儲層瀝青生物標志化合物的系統分析測試和混合成因氣的定量估算，闡明了該區嘉二段天然氣主要屬於二疊系腐泥型有機質成因氣，來源於二疊系過成熟為主的碳酸鹽巖烴源，主力氣源與嘉陵江組自身的碳酸鹽巖烴源無關，並具有油型裂解氣的地球化學特徵。 -

According to the comparison and analysis of mineral composition and geochemical characteristics of trace element, sulfur isotope, hydrogen and oxygen isotope, lead isotope and rare earth element in the gold ore and the altered spilite from the deposits of huachanggou gold mine, it was confirmed that the gold ore had obvious succession of the basic igneous rock
摘要通過對鏵廠溝金礦床金礦石和蝕變細碧巖礦物組成、微量元素、硫同位素、氫氧同位素、鉛同位素及稀土元素地球化學特徵地對比分析，得出金礦石對該基性火山巖存在明顯的繼承性。 -
Standard test method for determination of uranium content and isotopic composition by isotope dilution mass spectrometry
用同位素稀釋質譜法測定鈾含量和同位素成分的標準試驗方法 -
Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence, observation of thin sections, and analysis of sr and mn. the mn / sr value of all samples presented in this paper are less than 2, and the cathodoluminescence is dull, however, the samples from the cambrian underwent diagenetic alteration to a certain degree, and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete. the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world, supporting the notion of global consistency of strontium isotope composition of marine carbonates
根據鋸同位素地層學的基本原理，利用已有的鋸同位素演化曲線，筆者確定重慶秀山寒武系剖面寒武系底界、下一中寒武統界線和中一上寒武統界線都應適當下移；另外嘗試確定了重慶秀山寒武紀剖面一些關鍵點的年齡，累積厚度1380m處的年齡為503 ? 509ma ，累積厚度1900m處的年齡約為500ma ，這對秀山寒武系剖面下、中寒武統和中、上寒武統界線的確定具有參考價值。 -
