计算结果表明，阳坝花岗闪长岩的锆石饱和温度介于762～773oC，平均值为769oC，暗色微粒包体的锆石饱和温度介于752～770oC，平均值为760oC。

Currently, the main opacifier is zircon. Zircon crystals which formed in vitrified tiles have different refractive with glass caused light scattering, it makes vitrified tiles whiteness.

目前，玻化砖中乳浊剂主要采用的是锆英石，其增白机理是在玻化砖中形成硅酸锆晶体，利用硅酸锆晶体与玻璃相之间的折射率差使可见光发生散射，从而产生增白效果。

The results show that higher zircon addition resists the densification of fused magnesia zirconia materials,and the zircon addition influences the crystalline size of periclase,pore size and the pore structure significantly.

结果表明，配料中锆英砂含量的增加使熔浆的粘度上升，合成料难以致密化。锆英砂配入量对ZrO2晶形及晶粒尺寸影响不大，但明显影响方镁石的晶形、晶粒尺寸以及气孔的形状和尺寸。

After fired at 1600℃, with the increase of zircon addition the bulk density of the samples increases while apparent porosity decreases. When zircon addition is 4%, the strength is the best, and the photomicrograph of the sample exhibits a densely packed microstructure, with larger and better developed grains of periclase and spinel. Meanwhile, the direct bonding of solid phases is reinforced.

在1600℃热处理下，随着w(ZrSiO4)的增加，试样的体积密度增大，显气孔率变小，试样力学强度在w(ZrSiO4)为4%时达到最大值。w(ZrSiO4)为4%的试样整体显微结构致密，固相直接结合程度提高；并且方镁石和尖晶石晶粒的晶粒尺寸粗大，晶粒发育比较完整。

The zircon mineralogy and chronology of the eclogite show that a lot of primary inclusions of omphacite,phengite,garnet,bariosite etc.occur in the zircons,so the zircon should be formed during eclogite facies metamorphism.SHRIMP dating for zircons suggests the age of eclogite facies metamorphism range from 230 to 243Ma.

锆石矿物学和SHRIMP年代学研究表明，榴辉岩锆石中含有大量的绿辉石、多硅白云母、石榴子石、冻蓝闪石等矿物原生包裹体，锆石为榴辉岩相变质作用过程中从形成的变质锆石，锆石SHRIMP U—Pb年龄在230～243Ma之间，代表榴辉岩相变质作用的时代。

During retrograde metamorphism with amphibolite facies, a little Zr released from rutile, which was transformed into titanite, can be supplied to zircon overgrowth. Therefore, SHRIMP U-Pb ages of retrograde overgrowth zircon should represent retrograde amphibolite facies age.

在退变质过程中，金红石退变为榍石的反应可释放少量Zr，因此退变质增生锆石U-Pb年龄应指示角闪岩相退变质时代。

Based on zircon SHRIMP U-Pb, Sm-Nd and Ar-Ar isotopic datings and trace elements data of zircon and whole rock of the mafic granulite from Huilanshan in Lotian doming, we concluded that the protolith of the mafic granulite shoud be the Neoproterozoic mafic rocks, the granulite facies metamorphism of this rock was occurred at 124.0?.

罗田穹隆惠兰山基性麻粒岩的锆石U-Pb、Sm-Nd和Ar-Ar定年及锆石和全岩微量元素地球化学工作证明该麻粒岩的原岩形成于晚元古代，其麻粒岩相变质作用发生在124.0？。

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。

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。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
