首先，制造引力探测器B中4个高精度陀螺仪需要用到精度极高的球体。事实上，这些陀螺仪内部的转子是人类迄今制造过的最完美球体。它们的大小约相当于一个乒乓球，由熔凝石英和硅材料制成，其相对完美球体的误差在任何方向都不超过40个原子的厚度。这样高的精度是必须的，因为如果不是这样做，那么这些陀螺仪转轴的晃动将出现误差。<br /> <br /> 根据爱因斯坦理论进行的估算显示，地球周围空间的时空扭曲将导致陀螺仪旋转轴出现每年0.041弧秒的改变。1弧秒等于1/3600度。为了测出这样微小的改变量，GP-B探测器必须具备0.0005弧秒的精度。这就相当于让你测量放在100英里(约合161公里)之外的一张纸的厚度。<br /> <br /> 对此，威尔说：“GP-B探测器项目的工程师们不得不发明一整套全新的技术来满足这种不可思议的要求。”<br /> </td></tr></table> </div> <div id="comment_805799" class="cm"> </div> <div id="post_rate_div_805799"></div> </div> </dd> </dl> </div> </div>
