但是一個意外的事實引起了我的注意:某些礦物質(瀝青鈾礦物質、銅鈾雲母或鈣鈾雲母)的活性比根據其鈾或針含量所判斷的要高。None of the xenon isotopes we measured were the direct result of uranium fission
我們所測量到的氙同位素,根本都不是直接由鈾的核分裂而來。The simulation can be divided into three processes sequentially : calculating the induced fission neutron rate of uranium and space distribution by mam - li neutron source, computing the total uranium fission neutron count rate and time distributions of 42 3he tubes, and calculating the neutron coincidence counting rate
第一步,以ain ? li源為中子源,計算鈾的誘發裂變中子產生二率及空間分佈;第二步,以鈾的誘發裂變中子為中子源,計算化根』 ne管的總中子計數率及時間分佈;第三步,計算中子符合計數率。Based on features of natural electric potential in oxidation and reduction zones, it is held that the natural electric field method may determine the front line of the interlayer oxidation zone, and can hence infer the general position of the interlayer oxidation zone sandstone - type uranium deposit
根據氧化帶與還原帶的自然電位變化特徵,利用自然電場法可以確定盆地層間氧化帶前鋒線,由此推測層間氧化帶砂巖型鈾礦大體空間位置。According to the analysis on the lithogeochemical features and the carbon and oxygen isotopes of calcareous sandstones, it is realized that there some genetic relation between the formation of calcareous sandstone and uranium mineralization in the oxidation - deoxidation transitional belt, that is the precipitation and enrichment of uranium is accompanied by the deposition of carbonate and formation of calcareous sandstone
根據鈣質砂巖的巖石地球化學特徵,結合碳、氧同位素分析認為,氧化還原過渡帶中鈣質砂巖的發育與鈾礦化的形成具有一定的成因聯系,即在鈾沉澱富集成礦的同時,伴隨著碳酸鹽的析出作用,形成鈣質砂巖。Rather the lion ' s share was trapped in aluminum phosphate minerals, which contain no uranium at all
相對的,大部份的氙被囚禁在磷酸鋁礦物中,這種礦物根本完全不含鈾。Determination of carbonate in uranium ore concentrate by titration in non - aqueous solvent
鈾礦石濃縮物中碳酸根的測定非水滴定法Abstract : from radioactive equilibrium of natural radioactive decay series and content of several radioactive constituents, the formula for estimating activity of uranium ore and solid waste is derived and a case study on treatment engineering of decommissioning linchang uranium mine is presented
文摘:根據天然放射性衰變系列的平衡關系,推出了通過若干個而非全部放射性組分的監測數據來計算鈾礦石和固體廢棄物中放射性活度的公式,給出了臨滄鈾礦退役治理工程的估算實例。Aimed at attaining the purposes of different stages in the exploration of interstratified oxidation zone sandstone type uranium deposits, namely basin selection, area selection, sector selection, locating and exploration, this paper has put forward corresponding feasible geophysical and geochemical techniques evidenced by practical examples
摘要在層間氧化帶砂巖型鈾礦勘探中,根據選盆地選區選段定位勘探幾個不同階段的工作目的,提出相應可行的物化探方法,並用應用實例進行論述。The thinner uranium foil is better for neutron measurement, so the standards is designed to be made into thin disc ( thickness 1mm and diameter 40mm ) and will be combined with matrix properly to simulate the item which to be measured
根據中子測量的經驗,認為做成片狀較好,且鈾層的厚度越薄越好,但現在所具備的製作金屬鈾片的條件最薄只能做到1mm厚。According to the distribution features of vanadium, selenium, molybdenum and uranium at three interlayer oxidation zone tpye uranium deposits in northwestern china, their existence state and the mutual relation to uranium at known uranium deposits, it has been concluded that it is not sufficiently re - liable to make " spatial localization " of uranium ore bodies for interlayer oxidation type uranium deposits by prospecting the associated vanadium, selenium, molybdenum in soil
根據我國西北業已查實的3個層間氧化帶砂巖型鈾礦床中釩、硒、鉬與鈾的展布特徵,認為,按已知鈾礦床中鈾與釩、硒、鋁的存在及相互關系,試圖用壤中釩、硒、鉬測量對層間氧化帶砂巖型鈾礦實施伴生元素找礦或進行「空間定位」的依據尚不足。Abstract : it is thought that some parameters, such as elastic coefficient, u th ratio, gr hcgr, etc., might have relations to organic carbon content in formation according to the properties of hydrocarbon source rock
文摘:張立鵬,邊瑞雪,楊雙彥等用測井資料識別烴源巖測井技術, 2001 , 25 ( 2 ) : 146 152根據烴源巖的地質特點,提出了地層的彈性參數、鈾釷比等幾個參數也可以反映地層的有機碳含量問題。分享友人
