In Australia no exploitable uraniferous conglomerate has been discovered.

在澳大利亚，尚未发现可开采的含铀砾岩。

The influence of saccharomyces cerevisiae,seaweed, banyan leaves,firry cortex on adsorptive capacity of uranium was studied in order to seek cheap and effective biosorbents for environmental protection.

以保护环境为目的，以寻求廉价而有效的生物吸附材料为出发点，研究了啤酒酵母菌、北海海草、榕树叶、杉树皮等4种吸附剂对铀的吸附性能的影响。

Ordos basin accumulates various energy resources. Taking the oil, gas, coal and uranium in the basin as subjects, the scientists of China's State "973" multi-energy minerals enrichment project study the scientific issues of interest concerning the coexistence and accumulation of energy minerals in one basin, such as the material base and geodynamical settings the accumulation mechanism and enrichment environment, and the temporal and space distribution and control factors. This interdisciplinary study provides a new perspective on comprehensively understanding energy geosciences.

我国国家&973&多种能源矿产项目的科学家以富集多种能源矿产于一身的鄂尔多斯盆地为研究地区，以油、气、煤、铀为研究对象，探讨能源矿产同盆共存富集成藏的物质基础与地球动力学背景、成藏机理与富集环境、时空分布与主控因素等科学问题，这是通过多学科交叉综合研究能源地球科学的新视角。

The ~(233)U and the measured sample are mixed gravimetrically, then the R_(58)=~(235)U/~(238)U and R_(38)=~(233)U/~(238)U in the mixture are measured simuhaneosly, and the R_(38) can be considered as an internal reference standard.

233U和被测铀样按不同重量比被混合，然后，同时测量混合样中R_(58)=~(235)U/~(238)U和R_(38)=~(233)U/~(238)U，而R_(38)可被看作是内参照标准。

Methods:5Fliorouracil was added to culture medium of BGC823 gastric cancer cells and continuously cultured for 5h or 10h,then the human gastric cancer cells were stained with haematoxylin Eosin、dyed with immunohistochemical method and acid Ulead citrate,which was observed under light and electiom microscope.

目的：探讨5氟尿嘧啶对人胃癌细胞的结构和GSTπ表达的影响。方法：在人胃癌BGC823细胞株培养液中加入5氟尿嘧啶，继续培养5h或10h，然后用HE、免疫组化染色和铀铅染色。

在人胃癌BGC823细胞株培养液中加入5氟尿嘧啶，继续培养5h或10h，然后用HE、免疫组化染色和铀铅染色。光镜、电镜下观察。

A quantitative appraisal of the prospect of uranium mineralization is completed based on a set of hydrochemical data acquired from the known in-situ leachable sandstone-type uranium, including radon content, acid-alkali ratio, oxidized and reduced electronic potential, hydrocarbonate radical and uranium content in water.

但是在找铀过程中仅用水化学成份、氡含量、酸碱度和氧化还原电位等数值进行描述，说明它们与铀矿化的关系，这种单一因素的描述不能综合反映与铀矿化的联系程度，以定量评价铀矿化与上述因素的关系，从而影响了水化学找矿的效果。

His mother, Neelum, 22, from the state capital, Chandigarh , says he was born with hydrocephaly.

丘德哈利还在等待检验，但工作人员说他表现出来的症状与那些呈阳性的患者类似，把他列为疑似铀中毒。22岁的母亲尼鲁姆来自旁遮普邦首府昌迪加尔，她说小多尼生来就患有脑积水，他的腿就是个摆设。
