对添加不同陶瓷含量的试样进行镶嵌、打磨、抛光、腐蚀制成金相试样后,在扫描电镜下观察其组织,结果如图4 所示.由图4(a)和(b)可知,基体为深灰色组织,但在基体上分布着灰白色的颗粒,形态多数呈立方或六边形,在局部区域出现聚集现象.而在灰白色颗粒周围出现近似黑色的组织,多数白色颗粒镶嵌在黑色组织上(见箭头指向位置).随着反应物中AlTiO2B2O3含量的增加,白色颗粒的数量显著增加,并且更加细小,分布由聚集趋于均匀、弥散,在灰色基体中明显可见一种比例较高、形态不规则的黑色组织,如同白色颗粒周围的黑色组织一般,如图4(c)和(d)所示.将图4(a)中基体、白色颗粒及白色颗粒周围等典型区域测试显微硬度.结果表明：基体的硬度差别很大,深灰色部位的硬度较低,仅为600~650 HV100,基体中黑色部分的硬度高,达到1 360~1 580 HV100；白色颗粒的硬度最高,高达2 700~3 200 HV100,而在白色颗粒周围的黑色区域,硬度则在1 400~1 500HV100 之间,与基体中的黑色组织硬度接近.

不好意思,忙到现在啊 ,你这是论文么.
metallographic phase samples were made by inserting,rubbing,polishing and corroding the samples with different amount of ceramic content added.Observe the tissue of the metallographic phase samples under the Scanning electron microscope,the results shown as Figure 4.From Figure(a) and (b),we got to know that the tissue basal body in dark gray,but with greyish-white particles mainly in the shape of cube or hexagon distributed around it,and aggregation phenomenon found in some areas.Around the greyish-white particles,black-like particles were found and,most white particles were inserted to the black ones.(See Arrow pointed position).With the amont AlTiO2B2O3 of reactant increasing,the number of the white particles increased significantly,and became more leptos with even and disperse distribution tending.And the black tissue in irregular forms can be seen clearly in the gray basical body with higher proportion,which are similar to the tissue around the white particles as you can see from Figure (c)and (d).Test the micro – hardness of the basical body,whitel particles and their surrounding areas shown in Figure4(a),the result indicated that the micro-hardness varied a lot.the micro-hardness of the dark gray part is comparatively low as 600~650 HV100; the black part is as high as 1360~1580 HV100; the white part is the highest up to 2700~3200 HV100; while the black area around the white particles is between 1400~1500HV100,which is semilar to which of the black tissue of the basical body.
再问： 谢谢啊亲，麻烦你了~
