The influence of the thickness and concentration of the cap layer, as well as the component of the substrate, on the surface states is also obvious.
包覆层的厚度和掺杂浓度，以及基底的成分都能显著地影响表面电子态。
Therefore, matting some thickness crushed rock layer under the bottom of cap and compact properly may enhance greatly the bearing capacity.
因此，在承台底面下铺垫一定厚度的碎石层并经适当碾压，可大大提高承台的分担作用。
