For statically determinate frames, the stress-resultants at all sections may be found by statics alone . 对于静定刚架只用静力学就可以求出所有截面上的内力。
The rigid arm cc is simply a statement that the "plane sections" hypothesis may be applied to the shear wall . 刚臂CC只是说明了在剪力墙中可以应用“平截面”假设。
the bents supporting the four continuous 工 beam plate girders have a cross section shaped like a box. 构架支承着四片工字型板梁，构架的截面为箱型。
The cross sections for these fusion reactions are appreciable only for incident energies above 10 kev . 只有当入射能量超过10千电子伏时，这些聚变反应的截面才是可观的。
The pattern of woody increments can be readily observed on stumps and on the ends of cut sections of tree stems . 在伐根上和树干截面上，可以很容易地观察出木材生长模式。
It is obvious that the loading of fig. 19(a)produces both direct tension and bending stress on the cross section . 显然，图19（a）的加载在截面上产生了正的拉应力弯曲应力。
Gusts can cause variations in the test section dynamic pressure, and in the distribution of dynamic pressure across the test section . 阵风会使试验段动压和试验段截面动压分布发生变化。
It was found that fibers of circular cross section produce greater cohesion in webs and slivers than do trilobal fibers . 圆形横截面纤维在棉网和棉条中，比三叶形横截面纤维能产生较大的粘着作用。
Shear stresses and shear strains in prismatic members may be caused by either torsional moments, or by shear forces associated with flexure . 在等截面杆件中，剪应力和剪应变可以由扭矩引起，或者由变曲相关的剪力引起。
Numerical calculations have been made for wave-guides with a core of rectangular cross-section embedded in a uniform surround of lower refractive index . 对于掩埋在较低折射率的均匀介质中的距形截面芯子的波导曾作过数值计算。
