人造卫星的结构是卫星的基础,它就象一个建筑物的骨架,支托着星上的全部仪器和设备。建筑物的设计要尽量满足经济、实用、美观大方;人造卫星的结构设计要尽量做到质轻、可靠、便于操作。卫星的形状人造卫星是装在运载工具头部发射入轨的。由于容积有限,卫星的尺寸不可能做得太大。尽管如此,在这个有限的尺寸范围内,人造卫星仍然可以制造成各种各样的形状。球形和接近于球形的多面体是初期人造卫星常用的外形。我们知道,对于同样一个体积而言,在各种形状中以球形的表面积为 The structure of a satellite is the basis of a satellite, which acts like a skeleton of a building that holds all the instruments and equipment on the planet. The design of the building should try to meet the economic, practical, beautiful and generous; structural design of satellites should try to be light, reliable, easy to operate. The shape of the satellite The artificial satellite is mounted on the head of a vehicle to launch into orbit. Due to the limited size, the size of the satellite can not be too large. Despite this, satellites can still be made in a wide range of shapes for this limited range of dimensions. Spherical and nearly spherical polyhedron is the common shape of the early satellites. We know that for the same volume, the spherical surface area in all shapes is
