The paper analyzed the mechanism of diamond synthesis, stated and compared the processes and differences of diamond synthesis by slice and powder catalyst , and proposed the view of single room production mechanism.

文章分析了金刚石合成的机理，论述和比较了片状触媒和粉状触媒合成金刚石的过程和差异，提出了&单间生长机制&的观点，认为在粉状触媒工艺中金刚石生长的环境条件优越，合成出的金刚石晶体均匀对称，品质良好。

There are so many first products in Diamant Boart.

凭借其源源不断的创新精神，泰门宝引领着石材工具行业的潮流。1955年，泰门宝推出了第一套排锯；1968年设计出第一套大理石电镀金刚石绳锯；1985年推出了专切花岗岩金刚石绳锯；2005年在的多组绳锯上推出了新的7.3毫米的金刚石绳锯等等。

There have been a rapid development in the areas of the diamond resources prospecting, diamond mineralogy and diamond gemology .

在金刚石资源勘探、金刚石矿物学、金刚石宝石学研究等方面，都取得了很大的进展。

It is revealed that natural diamonds may contain as much as 59 different trace elements. The concentration of each trace element is above 1 ppm(10〓). However, the major impurities are nitrogen, hydrogen, oxygen and boron. The study of the forms of hydrogen in diamonds not only enriched the contents of mantle mineralogy, material sciences and gemology, but also provided some important informations for dealing with some problems concerning the Earth's mantle and core.

中文题名金刚石中氢的赋存状态研究副题名外文题名 The existing states of hydrogen in diamonds 论文作者杨志军导师谢先德研究员彭明生教授学科专业矿物学、岩石学、矿床学研究领域\研究方向学位级别博士学位授予单位中国科学院广州地球化学研究所学位授予日期2002 论文页码总数10，113页关键词空隙氢晶格氢金刚石馆藏号BSLW /2003 /P57 /1 天然金刚石中的微量元素达59种之多，其含量都在10〓级规模以上，且最主要的杂质元素为氮、氢、氧和硼等。

For this process,the free-standing diamond thick films were dipped in a saturated iron chloride solution and dried in atmospheric ambient.

其工艺为：自支撑的金刚石厚膜浸入饱和的三氯化铁水溶液中，然后平放在大气环境中干燥，将处理过后的金刚石膜放入MPCVD装置中，先用氢等离子体将氯化铁还原成铁，然后在800℃左右的温度下，利用铁对金刚石的催石墨化作用及氢等离子体的刻蚀作用将其表面刻蚀。

Although clad diamond prevent iron family elements from eroding diamond and improve the strength between matrix and diamond, there still are many problems in applying Fe-base formulae. After the adding amount of reinforced elements is determined, the effect of the basic elements of matrix on its comprehensive performance is studied. The results show that while wc content is 15%. Fe/Ni 1: 1, 663-Cu etc 50%, Sintering temperature 920℃, temperature kept time 1. 5 mintues, matrix comprehensive preformance is best.

尽管金刚石表面镀膜隔绝了铁族元素对金刚石的侵蚀和提高了胎体对金刚石的粘结强度，但以Fe代Co还存在胎体的综合机械性能等问题，本文试着从材料学的强化理论出发确定了微量元素的添加量之后，用正交试验设计方法研究了胎体的基本组元WC、Fe/Ni、663—Cu的加入量及烧结工艺对胎体综合机械性能的影响，得出在WC15%，Fe/Ni1：1，663—Cu等其它为50%，烧结温度920℃，保温时间为1.5分时胎体的综合机械性能最优。
