首先，给出含有半圆柱形弹性夹杂的弹性半空间表面上任意一点、承受时间谐和的出平面线源荷载作用时的位移函数。
Displacement function for an elastic half space with half cylindrical elastic inclusion bearing steady state line source force on horizontal surface is first given.
该机型不再使用单体圆柱形机身，而改用两个半圆柱形机身并排的设计，这样形成了更宽大的结构，从横截面上看，有如两个连在一起的肥皂泡。
Instead of using a single fuselage cylinder, they used two partial cylinders placed side by side to create a wider structure whose cross-section resembles two soap bubbles joined together.
