英汉例句

• Infrared spectrum tested asphaltine structure before and after reaction. Heavy components structure has changed after reaction, heavy components reduced and light components increased.

  采用红外光谱对反应前后沥青质的结构进行了测定，反应后沥青质中重质组分的结构发生了变化，重质组分的减少，轻质组分的增多。

• It can be inferred from activation energy that asphaltine is a complicated mixture formed with different molecular weights.

  由活化能可推测出沥青质是由不同分子量组成的复杂混合物。

• Group analysis of asphalt in BRA suggests that the content of the asphaltine is very high but the pectin content is lower compared with common oil asphalt.

  沥青组分试验表明，跟普通石油沥青相比，该种巖沥青的沥青质含量很高而胶质含量较低。

• The thermal weight loss of asphaltine in the pitch road building oil modified with different additives is studied with derivative thermo - gravimetric analyzer in inert atmosphere.

  在惰性气氛中，利用差热分析仪研究了不同添加剂改质煤沥青筑路油中沥青质的热失重情况。

• The experimental results show that the values of wettability index decrease with the increase in adsorption of asphaltine in crude, which causes the decrease of relative permeability to oil.

  实验结果表明，巖心润湿指数随沥青质吸附量的增加而减小，从而导致油相的相对渗透率降低。
