The project has used large-span secondary girder pre-stressed ceiling structure, which effectively reduces the beam cross-section height and ensures the total height and building height requirements.
工程中采用了大跨度次梁预应力楼盖结构，有效地降低梁的截面高度，确保层高和建筑物总高度的要求，此外还采用了超长混凝土结构无缝设计等新技术。
Particles of energy E are scattered by a certain potential well. In finding the total scattering cross section, the physical background are often ignored.
能量为E的粒子被某一势阱散射，如果推求总散射截面常常易忽视物理背景。
In the theoretical calculation of total reaction cross section, the results can fit the experimental data very well at high energy, but they are about 10%-20% lower at intermediate energy.
在对反应总截面的理论计算中，现有的理论计算值与实验数据在高能区可以很好的符合，但在中能区理论值低于实验值约10 %—2 0 %。
