求翻译：从图7(a)、(b)、(c)与图6可以看出，对同一种谐振频率（本文为36.5kHz）、同一种材料的阶梯盘，基底厚度越厚，主瓣的指向性将越尖锐，是什么意思？ 待解决

Figure 7 (a), (b), (c) can be seen in Figure 6, the same resonant frequency (this is 36.5kHz), the ladder of the same material plate, thicker substrate, the main lobe of the directivity will be more acute,

Figure 7 (a), (b), (c) and can be seen from figure 6, the same resonant frequency (article 36.5 ), kHz ladder with a variety of materials for the thick disk, substrate thickness, the flap on the point to nature will be the more acute.

From Figure 7(a), (b), (c) and Figure 6 may see, to the identical kind of resonance frequency (this article is 36.5kHz), the identical material steps and ladders plate, basis thickness is thicker, the main lobe directive property will be more incisive,

From Figure 7 (a) (on b) (on c) Figure 6 shows that same resonance frequency (this article 36.5kHz) ladder, same material, substrate thickness thicker, directivity of mainlobe will become acute,

Figure 7 (a), (b), (c) and can be seen in Figure 6, on the same resonant frequency (this article is 36.5kHz), the ladder of the same kind of material, substrate thickness thicker, mainlobe directed the more acute,
