It was observed that iron salts with lowerdecomposition temperatures exhibit higher activity when dry mixing method was used for preparation.
观察到在干混法制备催化剂时，所用铁盐分解温度越低活性越高。

At a lower level of decomposition it, too, could be described in terms of its constituent components.
在一个更低层级的分解中，它还可以进一步被描述为它自身的组成要素。

One way to resolve ignition and combustion difficulties for AN-based propellant is to lower AN decomposition temperature, and to accelerate the thermal decomposition of AN.
