摘　　要：在高等数学的研究中,最为广泛的是积分,包含了曲面积分、曲线积分、二重积分和三重积分等,它们应用比较广泛。物理学中平面薄片的重心非常重要,其研究往往要用到重积分。文章将从二重积分的定义、计算方法来研究其在平面薄片重心中的应用。In the study of higher mathematics, integral is the most widely used in many disciplines, ineluding surface integral, curve integral, double integral and three triple integral. The center of gravity of thin slice is very important, whose research are used with multiple integral. This paper discusses the definition and calculation method of double integral to study its application in the gravity center of the plane sheet.
