The metals, such as Fe, Cu and Co, which can be reduced by KBH〓, can not change the catalytic properties obviously if only small amount of them are added to Ni-B alloys; those who can not react with KBH〓, such as Zn〓, are washed out during the preparation, so they also can not change the catalytic properties; while addition of the elements in VIB group, such as Cr, Mo and W, can increase the hydrogenation activity magnificently.

同样，我们通过添加第三组分来修饰Ni-B合金，可以被还原的金属，如Fe、Co、Cu等，少量添加并不能明显改变其反应性能；而与KBH〓不发生反应的金属，如Zn，以离子形式加入后，除了少量离子被吸附在催化剂表面外，基本不残留在催化剂里，因此对反应性能也没有太大的改变；只有VIB族元素，如Cr、Mo、W的加入才会很大改进Ni-B催化剂在蒽醌加氢中的催化性能，尤以Cr的修饰作用最好。

The flame-retardant/smoke-suppressant of PVC may be divided into three kinds.

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。
