查询词典 uranium glass

The industry magnesia mainly uses in making the ceramics, the enamel, the fire-proof material and so on; In the polishing compound, the adhesive, in the paint manufacture takes the stopping; In the artificial fiber, the rubber (chloroprene rubber, fluorine rubber) make the promoter and the catalyst; Makes the antacid on the medicine in the laxative, uses in treating the hyperacidity, the stomach and duodenum ulcer; May take the hard sugar purification is the decolorant in the food processing, the ice cream pH value conditioner and so on; In the construction profession, the magnesia may the manufacturing contain the magnesium special cement and the heat preservation board and so on; The biggest use is serves as the fertilizer and domestic animal's feed in the agriculture, causes the plant and in the animal metabolism process principal element, when serves as cow's feed, may prevent because to lack nervous system function being out of balance which the magnesium causes, namely the so-called forage grass convulsion gets sick; Uses in the chemical industry making the metal magnesium and the magnesium chemical, like magnesium sulfate, magnesium chloride as well as other chemicals; Moreover also uses in the water treatment, the detergent which the flue was mad uses in the glass, the dye, the electric cable, the silcon steel industry, the uranium processing, the electronics industry, the insulation material industry, as well as uses in professions and so on petroleum chemical additive, casting, phenolic plastic.

工业氧化镁主要用于制造陶瓷、搪瓷、耐火材料等；在抛光剂、黏合剂、油漆的制造中作为填充料；在人造纤维、橡胶中作促进剂和催化剂；在医药上作抗酸剂于轻泻剂，用于治疗胃酸过多、胃和十二指肠溃疡病；在食品加工上可作为砂糖精制是的脱色剂，冰淇淋的pH值调节剂等；在建筑行业中，氧化镁可生产制造含镁特种水泥和保温板等；在农业上最大用途是用作肥料和牲畜的饲料，使植物和动物代谢过程中的主要元素，用作奶牛的饲料时，可防止因缺镁而引起的神经系统机能失调，即所谓牧草性痉挛病；在化学工业中用于制造金属镁和镁化学品，如硫酸镁、氯化镁以及其他化学品；另外也用于水处理，烟道气的洗涤剂用于玻璃、染料、电缆、硅钢工业、铀加工、电子工业、绝缘材料工业，以及用于石油添加剂、铸造、酚醛塑料等行业。

Important natural geological analogues are volcanic glass and meteoric glass(anal-ogues of solidified mass), clay minerals (natural analogues of backfill material), iron meteorite and copper deposits (natural analogues of waste containers), natural nuclear reactors, uranium deposits, iron deposits containing Th and REE and contact zones between igneous rocks and other rocks (natural geochemical analogues of HLW repository).

The efficiency of isotope exchange was only 2.84%, namely, the amount of less than 3% tritium was exchanged out of the glass uranium bed by deuterium, and after isotope exchange proceeded time after time, its standard deviation was 7.35%.

同位素交换法测量铀床氚的结果如下：加热充分解吸过的铀床经多次同位素交换后，其交换效率仅为2.84%，即不到3%的氚被氘气载带出来，其同位素交换法测量的标准差为7.35%。

Results showed that the amount of tritium residual in the glass uranium was 2.68%, namely there was (0.0308±0.0003) mmol tritium per gram uranium. The standard deviation of PVT measurement method based on the state equation of the ideal gas was less than 0.95%, when the pressure was between 1500 and 133332 Pa.

直接测量法测量铀床的氚残留量的结果如下：铀床的氚残留量为2.68%，即每克铀含(0.0308±0.0003) mmol 氚气；当压力读数在1500～133332 Pa之间时，基于理想气体状态方程的测量方法的标准差小于0.95%。

Examing neutron integral flux is an important part of fission track technique, and determining neutron integral flux by using uranium standard glass is recommended as a mainmethod by international Fission Track Standardization Group for age-dating.

监测中子积分通量是裂变径迹技术的重要组成部分。铀玻璃监测中子积分通量是国际裂变径迹定年标准化工作组推荐的重要方法之一，铀玻璃测定法还普遍用于测定样品中的铀含量及其空间分布。
