查询词典 diamond boron

It would still only be a fraction of the size, however, of the Cullinan diamond discovered in 1905, which was 3,106 carats when recovered and yielded a teardrop shaped diamond of 530 carats and is known as the Great Star of Africa.

然而，它的大小可能还只占一九O五年发现的库利南钻石的一小部分，当时发现的原石有三千一百零六克拉，后来切割琢磨出一颗五百三十克拉的泪滴型钻石，被称为「非洲之星」。

Diamond-shaped pieces, and a single diamond accent, are positioned in between the stones, creating an attractive pattern.

The matrix composites for diamond tools were tested with such modern testing instruments and equipments as DTA-7 differential thermal analyzer, JCXA-733 electronic probe and scanning electron microscope, JEM 2000 FX Ⅱ transmission electron microscope, eXL energy spectrometer, and humidity test instrument. The analysis, comparison, and induction of the testing results prove the enhancing effects of the rare earth on the matrix composites: degeneration, micro-alloying, purification, and catalytic activation. The comprehensive function of these effects leads to the decrease in the porosity of the matrix composites and to the increase in such actual indexes as the flexural strength, hardness, and impact ductility of the whole rare earth Fe-based diamond tool materials.

由DTA-7型差热分析仪、JCXA-733型电子探针及扫描电镜、JEM2000FXⅡ型透射电镜、eXL能谱仪以及莱茨2AP高温显微镜材料润湿性测试仪等现代测试仪器设备对金刚石工具材料进行了测试实验，对测试实验的结果进行了分析、比较和归纳，证实了稀土对胎体材料具有变性、微合金化、纯化和催化活化等四大强化作用机理，这些机理的综合作用导致了胎体材料孔隙率的降低和整个稀土Fe基金刚石工具材料抗弯强度、硬度及冲击韧性等实际使用性能的上升。
