The structure is resolved into several compound elements and every compound element consist of three parts: arch, trussed beam and lateral brace.

整个结构划分为若干组合单元，每个组合单元包括拱、桁梁及竖杆横撑架三部分。

The model also includes a set of reusable model elements that are useful in creating some of the compound elements; at least using these is simpler than creating them by hand.

模型还包含一组可以在创建一些复合要素时有用的可复用模型要素，至少使用这些要素要比手动创建更简单。

But this is a compound, right, it has some non-zero heat of formation from the elements. So is water, right?

但这是种化合物，对吧？,它具有非零的生成热,水也是一样，对吧？

Delta H of formation means the enthalpy of this compound minus the enthalpy of its constituent elements in their most stable state at room temperature and pressure.

生成焓就是这种组分,的焓减去它的所有组成元素,在室温和常压下处于,其最稳定的状态时的焓。
