这样可以极大地扩张其表面积，增加电荷负载，又不会降低材料的机械强度。
This massively increases their surface area and hence the charge they can hold, but without impairing the physical strength of the material.
如有必要，可将支点下放置一块垫板，以增加受力面积，将负载分散到地面。
If necessary, provide a wider base by putting the fulcrum on a board that will spread the load on the ground.
此外还对面积比、负重叠量、压缩性因数、负载惯量等对系统的影响进行了分析。
In addition to these, the influence of area ratio, negative overlap, compressive factor and load inertia on system behavior are also analysed.
