The results showed that for 2Y-TZP materials, because of low stabilizer content and small critical transformation size, more tetragonal zirconia could change into monoclinal, better effect of transformation toughening operated, hence higher fracture toughness was obtained.

晶粒尺寸、稳定剂含量对氧化锆陶瓷相变增韧效果具有重要的影响。2Y-TZP材料由于稳定剂含量低，临界相变尺寸也小，在低温烧结条件得到细晶粒情况下，断裂过程中有更多的晶粒达到或超过临界相变尺寸，因而具有更高的断裂韧性。

SHRIMP technique is applied to the age determination of Shuiquangou alkalic complex. Zircons from monzonite and syenite of the complex in the Dongping and Hougou gold mining district are dated at age of (390± 6) Ma and (386±6) Ma, respectively with U-Pb method. Rock-forming times of the complex is confidently constrained in the Late Caledonian-Early Hercynian period.

Apart from the amphibolite enclaves and dyke swarms, the isotopic ages of the magmatic intrusions have been measured. The magmatic sequence and geochronologic framework are as follows: Quartz monzonite, 1825 ± 23 Ma, TDM = 2920Ma; Throndhjemite, 2374 ± 10 Ma, TDM = 3460 Ma; Tonalite, 2604±102 Ma, TDM = 3063 Ma; Monzonite, 3096±17 Ma, TDM = 2978 Ma; Granite, 3605±43 Ma, TDM = 3528 Ma.

在野外建立热事件相对序列的基础上，通过单颗粒锆石U-Pb法测年和Sm-Nd同位素示踪研究，初步建立了该区早前寒武纪岩浆活动的年代格架：石英二长岩：1825±23 Ma，TDM=2920 Ma；奥长花岗岩：2374±10 Ma，TDM=3460 Ma；英云闪长岩：2604±102 Ma，TDM=3063 Ma；二长花岗岩：3096±17 Ma，TDM=2978 Ma；花岗岩：3605±43 Ma，TDM=3528 Ma。

The magmatic sequence includes, from older to younger, early-stage granite and monzonite , tonalite (with preserved amphibolite enclaves), trondhjemite, basic dyke swarm and quartz monzonite sills.

目前除斜长角闪岩包体和基性岩墙群尚未获得同位素年龄外，其他各期侵入体均已获得单颗粒锆石U-Pb测年数据。

Calidonian granites are widely developed in the Yema Nanshan area in the western segment of the Qilian orogenic belt. The geochemical characteristics of most of the granites are similar to those of adakites: SiO2≥56%, Al2O3≥15.0%, low MgO (average 2.04%), high Sr (257-889μg/g, average 546.42μg/g), low Y (7.1-25.3μg/g,average 16.67μg/g), average Sr/Y=5.89, no pronounced Eu anomaly and Sr positive anomaly. Adakites in this area have five rock types, quartz diorite, quartz monzodiorite, quartz monzonite, monzogrannite and hornblende granite. These rocks commonly contain hornblende, belonging to I-type granites.

提要：祁连西段野马南山一带发育大量的加里东期花岗岩，其中大部分花岗岩具有与adakite岩相似的地球化学特征，SiO2≥56%， Al2O3≥15.0％，低MgO（平均2.04％），高Sr(257～889μg/g，平均值546.42μg/g)，低Y（7.1～25.3μg/g，平均16.67μg/g），Sr/Y平均为35.89μg/g，Eu无明显负异常，Sr正异常，Adakite岩石类型有石英闪长岩、石英二长闪长岩、石英二长岩、角闪花岗岩、二长花岗岩，岩石中普遍含有角闪石，属I型花岗岩，地球化学图解反映该花岗岩形成环境为板块碰撞前的岛弧型，锆石U-Pb同位素年龄为444+38/-33 Ma，处在祁连造山带板块俯冲收缩阶段，因此可以推断野马南山埃达克质Adakite花岗岩是俯冲板片部分融熔和壳幔岩浆混合形成的。
