Fitting coefficients K were calculated by strength fitting calculation in Ashby formula, and the results are K0.75. ( 3) The energy-absorption characteristic of Al2O3k/ Al porous composites was studied.

计算了关于Ashby屈服强度公式中的拟合系数K，发现K0.75。（3）研究了Al2O3k/Al多孔复合材料能量吸收特性。

One was from about 1930 to 1965, when reclamation was unregulated, and the other from about 1970 to 2000 when reclamation was highly regulated ( Ashby 1998).

其一是从1930至1965年，当时不存在复垦的要求与法规，另一是从1970至2000年，这一时期矿山复垦有严格的法规管理（Ashby1998）。

Here, the difference of the present theoretical model from that presented by Gibson and Ashby is that, the former can directly use the "beam theory" conveniently whereas the latter can not.

本理论模型与Gibson和Ashby的有关理论体系的不同之处是，前者可直接运用梁理论进行方便的分析和推演，而后者则不能。
