鋯的 的英文怎麼說
中文拼音 [gàode]-
Back extraction by hno3 - hf and back extraction by concentrated hnch after lower the concentration of organic phase are studied, the method of back extration by hnorhf can not be used to icp - ms, because some zirconium is hydrolysis when hf is removed by heat. however, the method of back extraction by concentrated nitric acid after lower the concentration of organic phase can be used to icp - ms, the recovery is 93. 2 %, rsd % is 5. 24 %, the decontamination factor of uranium is 3. 2xl04, the detection limit of zirconium is 0. 04ng / ml. the method of tta extracting trace zirconium in uranium is firstly used to icp - ms, the result is satisfied, it can be used to determine zirconium in uranic production quickly and veraciously
本文通過研究hno _ 3 - hf反萃和稀釋有機相後用濃hno _ 3反萃這兩種分離方法，認為hno _ 3 - hf反萃由於在加熱去除hf時酸度不易控制，導致鋯的部分水解，因而此方法不宜用於icp - ms中，然而稀釋有機相後用濃hno _ 3反萃法用於icp - ms測量中，全程回收率為93 . 2 ，相對標準偏差為5 . 24 ，鈾的一次去污因子為3 . 2 10 ~ 4 ，鋯的測定下限為0 . 04ng / ml ，本文首次將tta萃取分離鈾中鋯用於icp - ms測量中，結果令人滿意，此方法適用於快速、準確測量鈾產品中微量鋯。Methods for chemical analysis of refractories containing zircon and or zirconia

鋯的強度幾乎與鋼相等，但它比鋼輕。It can determine the elements in water. when tta is used to extract zirconium in uranium, the combination of zirconium and tta is very strong, the concentrated acid of nitric acid and hydrochloric acid can not destroy their combination
用tta萃取分離鈾、鋯時， tta對鋯的螯合作用很強，硝酸和鹽酸的濃酸溶液並不能破壞它們之間的整合，即對鋯的反萃取非常困難。Crystal zirconium phosphate - phosphonate has the stability and regulity of interlayer floor of inorganic a - zirconium phosphate, they still have the designability of the organic group in the interlayer and adjustment of the ratio of organic and inorganic phosphorus acid, they are a kind of potential smart material, we can process molecule design and optimize filtration according to the requirement of goal reaction, we can prepare special ion - exchange, catalyst, catalyst supporters nonlinear optics compound, solid state proton conductivity and the intercalation complex precusor by introducing different active organic group or active center into the choice and stable framework of inorganic a - zirconium phosphate

層柱材料是近年來發展起來的一類多功能材料，由於其在離子交換、催化、固態質子導體、非線性光學以及醫學等方面的廣泛應用而受到國內外研究者的重視，大量文獻報道了-磷酸氫鋯zr （ hpo _ 4 ） _ 2 ? h _ 2o （ - zirconiumphosphate ，縮寫為- zrp ）的超分子插層化合物及插層性能，其中對不同的客體分子對磷酸鋯的嵌入做了詳細的報道，客體分子的種類包括氨、醇、氨基酸、蛋白質、酶、配合物、冠狀化合物等。Because the concentration of zirconium in uranium has large ranges, from 1. 50xlo ' 6 - 3. 8g / gu, not only how to decrease the remainder of uranium to eliminate its determinate effect but also how to acquire higher recovery of zirconium is considered, so the method of silica gel, the method of tbp levextrel resin chromatography, the method of tta chromatography and the method of tta extraction are compared. then tta extraction is chosen to acquire the ideal separation purpose. compared with icp - ms and icp - aes, xrf has characters of high repeatability, stability, low cost, high concentration elements analysis, the ability to determinate solid sample and having comprehensive practicability, but xrf has lower sensitivity, so how to increase the concentration of the sample to acquire better precision is a difficult problem, the optimum of operating condition : the integral time of spectral lines is 60s, the integral time of background lines is 20s, the voltage of xrf is 50kv, the electric current is 50ma
由於鈾中鋯的含量范圍很廣，從1 . 50 10 ~ （ - 6 ） 3 . 8g / gu ，在分離和測量時，既要考慮盡量地減少鈾的殘留量以消除鈾對鋯測量產生的影響，又要獲得鋯的理想的回收率，因此本文在分離方法的選擇上比較了硅膠吸附分離法， cl - tbp萃取色層法， tta萃取色層法和tta萃取分離法的優缺點，認為tta萃取分離法可以達到理想的分離效果。Zirconium alloys are employed extensively in light water cooled reactors ( lwr ) as the cladding materials of fuel elements and other structural materials because of the low capture cross - section for thermal neutrons, good resistance to water - side corrosion at elevated temperature, adequate mechanical properties and high thermal conductivity
由於鋯的熱中子吸收截面小，並具有優異的耐高溫水腐蝕性能、良好的綜合力學性能和理想的熱導率，因此，鋯合金被用作核電站水冷動力堆核燃料元件的包殼材料和堆芯的其它結構材料。Methods for determination of zirconium in steel
