  “硫化初期”译为未确定词的双语例句
     FZC series residue hydrotreating catalysts developed by Fushun Research Institute of Petroleum and Petrochemicals have been sulfurized with two different test methods at the pilot unit. The result shows that under the conditions of pressure and temperature unchanged, sulfurization has been sped up by properly increasing the sulfur-izing agent usage at the primary period of catalyst sulfurization an enhancing the H2S/H2 ratio of recycle hydrogen.
     采用抚顺石油化工研究院开发的FZC系列减压渣油加氢处理催化剂,在中试装置上进行两种不同方法的硫化试验,结果表明,在硫化压力、温度不变的情况下,适当提高硫化初期硫化剂用量,增大循环氢中H_2S/H_2比值,可以提高催化剂的硫化速度;

     The valence variety on LaCoO 3 surface in various processes of activation sulfurization was investigated. When LaCoO 3 was pre poisoned by SO 2, the adsorbed oxygen on its surface was absence, the chemical shift of binding energy of Co 2 p 3/2 was more than 1.0 eV, the La 3 d double peak turned unobvious, and at the same time the S 4+ appeared on the surface, indicating that the perovskite was overlapped by the strongly adsorbed SO 2 species.
     在硫化初期 ,经SO2 预中毒后 ,吸附氧种不存在 ,Co 2 p3 / 2 结合能发生明显的位移 ,La 3d的XPS双峰变得不明显 ,同时出现不稳态的S4+ 物种 ,表明催化剂LaCoO3 被SO2 的强吸附所覆盖 ; 催化剂LaCoO3 仍为钙钛结构并没有新的物相产生 ,SO2 中毒仅在催化剂表面进行 .
