锆的

Although diamonds are harder than zircons, they are quite young in comparison: a mere 3.3 billion years old.

虽然要比锆钻石，他们是相当年轻的比较：只有33.00亿岁。

There are three stages upon formation sequence of the zircons.

按形成的先后顺序至少存在Ⅰ期、Ⅱ期和Ⅲ期等3期锆石。

The upper intercept age indicats a low limit of crystal age of the zircons and suggests a basaltic volcanic event at 1.8 Ga ago in this area.

其上交点年龄指示了该锆石的最小结晶时代，它表明在18亿年时该地区曾有一次玄武质火山岩事件。

Because zircons are 8-10 feet below the surface of the earth under the earth, and in addition to local deposits located below the horizon, so that when water is often flooded mines.

因为锆石大多位于表土层下8-10英尺下，且当地的矿床又多位于水平线以下，因此开采时水经常会淹没矿坑。

We try to use Cr thin films to improve Zircaloys properties on the background of engineering application.

基于某工程应用研究背景，我们尝试用铬来提高锆合金的性能。

Time of flight inductively coupled plasma mass spectrometry was used for determination of nine trace and ultra- trace elements in the steel, nickel-base alloy and zircaloy.

在微波辅助系统中对屑状的样品进行湿法消解，采用飞行时间电感耦合等离子体质谱测定钢、镍基合金及锆锡合金中9种痕量和超痕量元素元素。

Time of flight inductively coupled plasma mass spectrometry was used for determination of nine trace and ultra-trace elements in the steel, nickel-base alloy and zircaloy. The chips samples were wet-digested using a microwave assisted system.

This Slide Pendant is Solid Sterling Silver Rhodium Plated and Hand Inlaid with Synthetic Blue Opal and accented with small Cubic Zirconia Stones.

这张幻灯片是实心纯银吊坠镀铑的合成和手镶嵌蓝色蛋白石和重音与立方氧化锆石小。

Insertion of ethylacetate or DMF into 1-zircona-2-azacyclopent-3-ene complexes at 50 oC affords pyrroles in moderate yield when they quenched with KOH aqueous.

1-锆-2-氮-环戊-3-烯错合物在室温下可与乙酸乙酯或DMF进行插入反应，经由氢氧化钠水溶液水解后，可得到不错产率的比咯。

We can manufacture and supply of various colors Cubic Zirconia circular AAA, AA, A-level and quality of products, precision grinding, high-quality.

我们能够制造及供应各种颜色立方氧化锆圆形AAA、AA、以及A级质量的产品，精确打磨、质量上乘。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
