由于那克土恩不能制造出高移动速度和小巧的陆地飞毛腿引擎，所以军团以连队为单位雇佣了许多类似的快速移动和反应部队。
Specifically , to a test particle , its mass defect is am = m _ ( 0 ) - m , where mo and m are the mass of the particle when it is in the infinity and in the grav - itational field , respectively . to a spherical shell ( or a solid sphere ) , its mass defect is am = m _ ( 0 ) - m , where mo is the total mass of the matter scattering in the infinity and m is the mass of the gravitational spherical shell ( or the gravitational sphere ) combined by the matter scattering in the infinity
具体来说，对于试验粒子，当它由无穷远处运动到引力场中某点时，其质量由m _ 0变为m ，发生的质量亏损为m = m _ 0 - m ；对于球壳或固体球，当组成球壳或固体球的这些物质分散在无穷远处时，总质量为m _ 0 ，当这些分散在无穷远处的物质结合成球壳或固体球时，其质量变为m ，发生的质量亏损为m = m _ 0 - m 。
