In an embodiment, the selective hydrogenation catalysts of this disclosure are used in the hydrogenation of highly unsaturated hydrocarbons such as for example and without limitation acetylene, methylacetylene, propadiene or combinations thereof.

在实施方案中，本公开的选择性加氢催化剂被用于高度不饱和烃的加氢中，其中所述高度不饱和烃例如但不限于乙炔、甲基乙炔、丙二烯或它们的组合。

The unsaturated hydrocarbon stream 10 primarily comprises one or more unsaturated hydrocarbons, but it also contains one or more highly unsaturated hydrocarbons such as for example and without limitation acetylene, methylacetylene and propadiene.

所述不饱和烃料流10主要包含一种或多种不饱和烃，但它也含有一种或多种高度不饱和烃例如但不限于乙炔、甲基乙炔和丙二烯。

Then the paper used the projection operator to structure the normal coordinate component,thus combined 15 normal vibration patterns of propadiene molecule.

先对丙二烯振动模式进行分类及构造投影算符，再用投影算符构造简正坐标分量，从而组合出丙二烯分子的15个简正振动模式。

The main objective of this research project is to modify the Methyl-Acetylene/propadiene selective hydrogenation reaction system of the No.3 Naphtha Cracker in CPC. The original gas phase reaction system was redesigned to a liquid phase reaction so that higher propylene selectivity was achieved and lower rates of propane and green oil were produced. To recover effectively the higher production of valuable propylene from the reaction system, the following fractionator was also redesigned.

本研究之目的在於修改中油公司三轻工场老旧的甲基乙炔／丙二烯选择性氢化气相反应系统，使成为液相反应系统，藉由液相反应的优异性，提高由MAPD氢化得到丙烯之选择率，同时降低丙烷及绿油产率，以增加丙烯产率，另亦修改丙烯精馏系统，以提升蒸馏塔提纯之效率。

The reaction results of the selective hydrogenation of MethylAcetyleneand Propadiene in C 3 distillate by catalytic distillation were investigated with randomlypacked structure of packingtype catalyst, the combined structure of sieve tray and packingtype catalyst as well as the structure with interlaced packing and ordinary catalyst.

考察了填料状催化剂散装结构、筛板填料状催化剂复合结构、规整填料与普通催化剂交错排列结构等用于C3 馏分中丙炔、丙二烯催化蒸馏选择加氢过程的反应效果，综合考虑催化剂制备的难易、工业装置长周期运转的必要性、传质对反应的影响等因素，推荐在工业装置上采用规整填料与催化剂交错排列结

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
