英汉例句

• The formation of ballas is observed with increasing carbon supersaturation (CH4 content) in the gas phase respectively with decreasing at. H/C ration.

  随着H/C比率减小，气相中碳的超饱和度（CH4含量）相应增大，从而形成半刚石。

• In all cases Raman spectra showed clearly the formation of the ballas diamond.

  就一切情况而论，拉曼光谱明显反映了半刚石的形成。

• In general it is difficult to determine the exact transition temperature between ballas and faceted growth, due to numerous other parameters within an experimental setup.

  总的来说，由于在一个实验装置内有许多其它参数，要準确测定半刚石和多面金刚石生长的转变温度是不容易的。

• This was observed by diamond deposition on iron substrates where, due to the high vapor pressure of iron, ballas is formed at methane concentrations lower than 0.4%.

  这一点是在铁基体上沉积金刚石时发现的。这时，由于铁的蒸汽压力很高，在甲烷浓度低于0.4%时可形成半刚石。

• Some examples should show that the deposition of faceted or ballas diamond is strongly related to the deposition parameters.

  一些例子可以说明，多面金刚石或半刚石的沉积与沉积参数有着密切的关系。

• In order to use the high potential of the unique ballas structure in industrial applications further investigations should be performed on the low-pressure ballas synthesis.

  为了在工业应用中发挥独特半刚石结构的巨大潜能，须对低压半刚石合成进行进一步的研究。

• From the present point of view the ballas morphologies can be described by various microstructures.

  按照目前的观点，半刚石的形貌可通过多种显微结构加以描述。

• The hydrogen measurements by SIMS indicate the higher hydrogen contents in the ballas layers, originating apparently in the amorphous inclusions which are saturated with hydrogen.

  SIMS氢测量说明，半刚石涂层中的氢含量较高，显然，这些涂层是从H2饱和的非晶态杂质中产生的。

• Generally an increasing concentration in CHx compounds leads to ballas deposition.

  通常情况是，chx化合物中浓度增大会导致半刚石沉积。

• It must be noted that the Raman intensity (background) increases strongly due to the morphological change from faceted to ballas diamond.

  必须注意的是，拉曼强度(背景)因形貌从多面金刚石变成半刚石而得到明显的提高。

• Several morphological ballas structures have been observed by varying the deposition conditions, i. e. ballas having faceted areas, flat ballas, ballas with graphitic inclusions, etc.

  通过改变沉积条件，发现了几种形貌的半刚石结构，即具有多面的半刚石、平整的半刚石和含石墨杂质的半刚石等等。

• The ballas type grown at the transition to the graphitic deposition is characterized by a homogenous micro-twinned matrix.

  在向石墨沉积转变中生成的半刚石种类的特征是均匀的显微孪晶基体。

• Ballas types grown under conditions adjacent to the faceted diamond region were called coarse ballas in earlier publications.

  在邻近多面金刚石区域的条件下生成的半刚石在以前的刊物中被称作粗大的半刚石。

• Applying polycrystalline ballas diamond as material for high-duty, thin coating surfaces on suitable substrates with even complex pre-shaped geometries should be quite easy.

  在具有更为复杂的预成形几何形状的适当基体上将聚晶半刚石用作高强度薄涂层表面材料应当说是很容易的事情。

• In flat ballas the D-band is smaller and the graphite peak larger than in coarse ballas.

  在扁平的半刚石中，D带较小，而石墨峰比粗大的半刚石中的要大。

• The described nano-crystalline diamond deposits show nearly the same Raman peaks as ballas deposits and also the TEM images look very similar.

  上述纳米晶金刚石沉积物显示出与半刚石沉积物几乎相同的拉曼谱峰，而且TEM图象也十分相似。
