一、概述 铍是一种有色稀有轻金属,它具有比铝合金、镁合金、钛合金比重小,热膨胀适应性好等特点,是制作惯性器件理想的材料。国外自60年代起开始应用,目前已广泛采用。为了提高陀螺仪表精度的稳定性能,1980年起我所开始利用铍材料制作陀螺浮子组件中的部份零件。 First, an overview of beryllium is a non-ferrous light rare metals, it has a smaller than the proportion of aluminum alloy, magnesium alloy, titanium alloy, thermal expansion and good adaptability, etc., is the ideal material for the production of inertial devices. Foreign applications since the 1960s, has been widely adopted. In order to improve the stability of the gyro meter precision, from 1980, I started using beryllium material to make some parts of the gyro float assembly.
