轮船的甲板成近似半椭圆面形，为了得到甲板的面积，首先测得横向最大相间8.534米，然后等距离的测得纵向高度，自左向右分别为

0.914, 5.060, 7.772, 8.717, 9.083, 9.144, 9.083, 8.992, 8.687, 7.376, 2.073 米

选择三种算法计算甲板的面积，并进行比较分析-The deck of the ship is approximately semi-elliptical, and in order to obtain the area of the deck, the transverse maximum maximum is 8.534 meters, and then the vertical height is measured　the left to the right

0.914, 5.060, 7.772, 8.717, 9.083, 9.144, 9.083, 8.992, 8.687, 7.376, 2.073 meters

Three algorithms were chosen to calculate the area of the deck and compare and analyze
