Three variables are considered: critical buckling position, and neutral plane, the fiber buckling half-wavelength.
引入三个变量:临界屈曲位置、中性面位置和纤维屈曲半波长。
As the size of coal pillar increases, the width of neutral plane area increases. However, the speeding-up of neutral plane area occupying the width of coal pillar decreases and becomes stable.
随煤柱尺寸增加,中性面区域的宽度逐渐增大,但其占煤柱宽度比例增速降低并逐渐趋于稳定。
This plane is therefore called the neutral surface of the beam.
因此这个平面称为梁的中性面。
