锆

The reactions and transformation have resulted in a great volume increase and thus destroyed the structure,weakened the strength and corrosion resistance of the materials.

这一系列反应使试样产生很大的体积膨胀，从而破坏了制品结构。因此，与镁炭砖不同，Al和Si不但不能增强镁锆炭砖，而且使其结构破坏和耐侵蚀性降低。

Zircon jewelry should be stored carefully because although this ancient gem is hard, facets can abrade and chip.

锆石饰品应存放小心，因为虽然这个古老的宝石难、面、筹码可以研磨。

It is widely attached importance to using it to solidify actinides which are separated form high level radioactive waste.

钙钛锆石是主要的人造岩石固化基材之一，在固化处理从高放废物中分离得到的锕系元素方面受到广泛重视。

In addition, different reaction parameters have been further studied on the synthesis of cubic mesoporous silica.

这种立方介观结构的磷酸氧锆介观结构材料具有很高的热稳定性。

Alkalescence a flux, such as alkali metals and alkaline-earth metal, zinc oxide and most stain oxide or chromophores components are gender neutral, the principal is alumian oxide, sometimes hemaite and electrolyic, and so on are also included in this composition; acidic components of oxide for silica, phosphoric acid, zirconia, etc.

碱性成分为熔剂，如碱金属、碱土金属、氧化锌及多数的着色氧化物或发色基团；中性成分为两性氧化物，主体为氧化铝，有时将氧化铁和氧化锰等也列入此成分中；酸性成分中有代表性的氧化物为氧化硅、磷酸、氧化锆等

The 207Pb/206Pb age (593Ma) of single zircon of quartz-syenite porphyry reflects that the intrusion of subvolcanics is accompanied by capture of paleo-zircon of the basement rocks, implying that the Precambrian continental basement possibly exists below Aqishan-Yamansu volcanic island arc.

而石英正长斑岩单颗粒锆石207Pb/206Pb年龄值(593Ma)反映了岩体侵位过程中捕获了基底岩石中古锆石的年龄信息。进一步推测在阿齐山－雅满苏火山岛弧之下可能存在前寒武纪陆壳基底。

Some data about apparent solubility product of Mo and Zr precipitates have been determined in 1.0, 2.0, and 3.0 mol/L HNO 3 solutions. The effects of different concentration of nitric acid and initial concentration of Mo and Zr on the apparent solubility product are also investigated.

实验还测定了 1 0 ，2 0 ，3 0mol/L硝酸溶液中钼锆沉淀的表观溶度积K′sp，讨论了硝酸浓度、钼锆初始浓度对表观溶度积的影响。

It is concluded that the ~(176)Hf/~(177)Hf ratios of 91500, Temora and We-1 were homogeneous, because the aforementioned Hf isotopic results consist of at least seven separated performances of aliquots for each zircon sample. These results have significant implications for zircon Hf isotopic determination by using LA-MC-ICPMS.

上述每个结果包括至少7组独立的锆石样晶的溶解、分离和测定，表明标准样91500、Temora和We-1是Hf同位素组成均一的，可作为LAM-MC-ICPMS(激光剥蚀多接受器电感耦合等离子体质谱)的原位微区锆石~(176)Hf／~(177)Hf比值分析过程中外部校正及监控标准样。

Other alternate clear/white stones are Zircon, Cubic Zirconia, and White Sapphire.

其他候补清晰/白色的石块，锆石，立方氧化锆和白宝石。

The carboxylic acid and its ester may have straight chain or branched chain, and the catalyst is solid in the carrier of zirconia in precipitation process sol or marketable product.

其中，羧酸及其酯为C 2-20 羧酸及其酯，可以是直链或支链，催化剂是以固体的形式加入，载体二氧化锆是以沉淀法制备的凝胶，也可以直接用市场上购买的二氧化锆。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
