Frequency distributions of element combinations may find compound elements that do uniquely determine the data.
元素组合的频率分布可以发现能够惟一确定数据的复合元素。
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。
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。
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?
Well, I need to write the reaction that forms that compound from it's elements, right?
我需要写出从元素单质生成,这种化合物的反应,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。
