Fig.1 shows that diamond particles are dispersed in the
copper matrix.Since the diamond particles are easy to be
stripped off during mechanical polishing,small pits are left
on the surface of samples.When the samples were analyzed
by electron probe for carbon,the particles displayed high
carbon peaks,as shown in Fig.2.
Fig.3 exhibits the analyzed result for extracted
product of the copper–diamond composite by X-ray
diffraction (XRD) analysis.It is shown that three dif-
fraction peaks exist,shown as A,B and C,respectively.
The interplanar distances corresponding to the three
peaks and standard ones for diamond are compared in
Table 1.The measured values of the interplanar distances
are in good agreement with the standard ones,demon-
strating that the extracted product should be the carbon
in diamond state.
Fig.4(a) gives a TEM micrograph showing distribution
and morphology of diamond particles (indicated as A,B,
and C) in the copper–diamond composite.The calibration
of interplanar distance for diffraction rings in Fig.4(b) was
given in Table 2.Compared to Table 1,it is also demon-
strated that the calibrated interplanar distances for the
diffraction rings conform to the standard ones of diamond.
Therefore,it is believed that the graphitization of diamond
particles hardly occurs after sintering at 1150–1220 K in the
copper–diamond composite.
Although diamond is a metastable allotropic modifica-
tion of carbon,the graphitization of diamond particles in the
copper–diamond composite did not occur,or the degree of
graphitization was too small to be found.
It is believed that the beginning temperature of graphi-
tization would be associated with the purity of diamond
powders.The impurities such as some metallic elements
reduce the beginning temperature of diamond graphitiza-
tion.When diamond is fabricated by the static synthesis
method,Fe and Ni are often used as catalysts and are
present in diamond as impurities to decrease the beginning
temperature of graphitization [6].It is understandable that
both for the graphitization and its reverse reactions,their
activation energies can be decreased by catalytic agents.
Compared with the diamond fabricated by static synthesis,
the diamond powders prepared by explosion method do not
contain metallic impurities,thus leading to an obvious
increase in the beginning temperature of graphitization.
Hence,the detonation synthetic diamond might be more
resistant to graphitization and probably suitable for the
electric contact materials.

图形一展示了 钻石颗粒可以分散在铜质型片里
Since the diamond particles are easy to be
stripped off during mechanical polishing,small pits are left
on the surface of samples.
由于这些钻石颗粒在化学抛光的过程中很容易分离出来,所以样品的表面会留下小凹痕
When the samples were analyzed
by electron probe for carbon,the particles displayed high
carbon peaks,as shown in Fig.2.
当这些样品电子探针被分解时,这些微粒表现出高的碳值（carbon peak是某化学术语吧,不了解）就如2图所示

It is shown that three diffraction peaks exist,shown as A,B and C,respectively.
（他说明如果衍射峰存在的话,就分别像A,B,C）
The interplanar distances corresponding to the three
peaks and standard ones for diamond are compared in
Table 1.
（这些对应三个峰的晶面间的距离,和标准值在图一中作了对比）
The measured values of the interplanar distances
are in good agreement with the standard ones,demon-
strating that the extracted product should be the carbon
in diamond state.
(经过测试的晶面间的距离和标准值一致,说明这些提取物质应该是钻石形态时的碳 ）（神马竟然还有钻石形态,总不能是钻石州吧）

与一相比,他也说明了图四晶面间的距离衍射环的校准与标准样本相符
Therefore,it is believed that the graphitization of diamond
particles hardly occurs after sintering at 1150–1220 K in the copper–diamond composite.
所以说,钻石颗粒的石墨化几乎不会发生在尽力了1150-1220k在铜钻化合物烧结过后
Although diamond is a metastable allotropic modification of carbon,the graphitization of diamond particles in the copper–diamond composite did not occur,or the degree of
graphitization was too small to be found.
（尽管钻石是碳的同素异形体,钻石的石墨化在铜钻化合物中不会发生,或者就是石墨化程度很小,没有发现）
It is believed that the beginning temperature of graphi-
tization would be associated with the purity of diamond powders.
我们相信石墨化的温度和钻石的纯度有关
The impurities such as some metallic elements reduce the beginning temperature of diamond graphitization.
像金属元素这些杂志,减低了需要石墨化的温度
When diamond is fabricated by the static synthesis method,Fe and Ni are often used as catalysts and are present in diamond as impurities to decrease the beginning
temperature of graphitization
（在用静电合成方法构造钻石时,Fe和镍是作为催化剂的,他们也作为杂质减低了钻石石墨化的温度）
[6].It is understandable that both for the graphitization and its reverse reactions,their
activation energies can be decreased by catalytic agents.
（这很容易理解,石墨化合它的逆向反应,他们的发生能力都会因为催化剂而降低）
Compared with the diamond fabricated by static synthesis,the diamond powders prepared by explosion method do not contain metallic impurities,thus leading to an obvious
increase in the beginning temperature of graphitization.
（与用静电合成方法构造的钻相比石,用爆炸方法取得的钻石不包含金属杂志,提高了石墨化的起始的温度）
Hence,the detonation synthetic diamond might be more
resistant to graphitization and probably suitable for the
electric contact materials.
（因此,爆炸合成的钻石更加能抵制石墨化,同时也更合适和电接触的物质,就是带电体）
