翻译一段Gibson官网对弧面面板的描述：
Radius Top
The top of many “flat-top” guitars are under a lot of stress from the pull of the strings, which can eventually compromise the top. So, while most acoustic guitars are true “flat-top” guitars, all of the acoustics produced by Gibson in Bozeman, Montana have a radiused, or “tuned” top. Instead of being perfectly flat, a radiused or “tuned” top is raised slightly, and a special instrument is used to shape the top braces to the radius of the top. This process adds tension and strengthens the top, creating a less stressful joint where the top meets the sides and reducing the stresses of string pull. It also results in a “speaker cone” effect that maximizes sound projection, adding a significant boost to mid-range levels for a more balanced acoustic tone.
弧度面板
箱琴（注：英文里用”平面板“吉他指代箱琴，区别于f孔爵士吉他和实心电吉他）的面板受到来自琴弦大量拉力，这些拉力最终会破坏面板。因此，当多数原声吉他是真正的”平面板“吉他时，在波兹曼生产的所有Gibson吉他都拥有一个带有弧度的，或者称作”调整式“面板，而不是完全平面的面板。带有弧度的面板会微微凸起，（工厂）使用一种特殊的设备来制造这种面板的音梁。这种工艺可以为面板提供额外的张力，使其更加坚固，降低面板和侧板结合处的拉力（应力集中？）和弦对面板的拉力。这同时会带来一种类似“扬声器纸盆”的效果，可以让声音辐射最大化，加强中频的声音，带来更加均衡的原声音色。 |

正常的哈。不必要担心太多
