Question

跪求高人帮我翻译一段英文

Under the conditions of catalysis the precursors underwent a transformation leading to a very active and selective crystallized solid. Most of the solids contained only one phase never shown to be present in iron phosphate-based catalysts until now. However in some cases a型 and b型Fe3(P2O7)2 were also observed. The parameters governing the presence of these phases and their effect on the catalytic properties of the catalysts is described else where (22).

Answer 1

在前体催化的条件下的化学变化会形成一个非常活跃并具有选择性的结晶固体。大多数的固体在磷酸铁基催化剂催化下有一个阶段直到现在都没有当场被观察出来。然而在A型和B型Fe3(P2O7）中这个阶段确实被观测出来的。关于这些阶段的参数以及它对于催化剂催化性能影响的参数在其他地方也有所描述

Answer 2

在催化作用的情况下先驱经受一导致一非常活跃和仔细挑选结晶的固体改变.固体大部分的含有,从不向仅一阶段展示到现在为止在铁磷酸盐-中向是礼物把催化剂放置在基座上.但是在有些情形下a型和b型Fe3((P2O7)2被也注意到.管理这些阶段的存在参数和他们的对催化剂存在的催化的小道具的影响其他描绘地方(22).
绝对正确！
