The integral outer shape of the packing box is similar to a steam locomotive, and the modeling is beautiful.
本包装盒整体外形与蒸汽火车头很相似，造型美观。
The boiler used by such locomotive was the one removed from a small winder, the wheel being bought as the waste cast iron, and the body framework was made from U-shape iron.
它用的锅炉是从一个小型卷扬机上拆下来的，车轮是当铸铁废料买来的，车身支架是用U型铁制造的。
This calculating technique then attempts to be applied to the box-shape-section lateral beam in the bogie's frame of SS7E electro-locomotive in order to obtain the FEM calculating results.
基于这种方法，以SS_（7E）型电力机车转向架构架箱型变截面侧梁为应用对象，创建了有限元求解模型。
