求翻译：现代飞机的机翼通常采用铝合金蒙皮,它的厚度随机翼的结构形式和它在机翼上的部位确定.由于机翼前缘承受的局部空气动力较大,飞行中又要求它能够更准确地保持外形,而翼根部位承受的扭矩和弯矩通常较大,所以一般机翼的前缘和翼根部位蒙皮最厚,后缘和翼尖部位蒙皮较薄.为了避免由于各块蒙皮的厚度不同而影响机翼表面的光滑性,某些飞机还采用了变厚度的过度蒙皮.现代飞机的某些操纵面采用了复合材料.是什么意思？

The current aircraft wing usually uses the aluminum alloy outer covering, its thickness along with wing structural style and it on wing spot determination. Is big as a result of the leading edge withstanding partial aerodynamic force, in the flight requests it to be able to maintain the contour accu
