我们建议在保证结构强度的前提下采用多孔梁以整合管线布置，能够更有效的释放空间高度。

We suggest that under the premise of structural strength, using porous beam to integrate pipeline layout in order to release space height effectively.

艾氏冲击试验：用规定高度的摆锤对处于悬臂梁状态的缺口试样进行一次性打击，测量试样折断时冲击吸收功的试验。

The impact test of the pendulum is used to strike the notched specimens of the cantilever beam with a prescribed height, and the test of impact absorbing power when the specimen is broken.

应用龙格库塔法解非线性方程得到了该问题的数值解，给出了截面高度随梁长的变化曲线。

The numerical results of nonlinear formula were obtained by the Runge-Kutta method, and we have also obtained the curve of the height of the example.
