3. AUTO GROUND: Automatic ground balance - raise search coil off ground, press the AUTO GROUND button, lower the coil to the ground, and release the button for precision auto-balancing. 自动地面：地面自动平衡-提高搜索起飞地面线圈，按AUTO按钮地面，降低线圈到地面，并释放精密自动按钮平衡。
4. The resultant of a coplanar system of concurrent forces is equal to the geometrical sum of these forces and it applies to the point of intersection of these forces. 平面汇交力系的合力等于各分力的矢量和，合力的作用线通过各力的汇交点。
5. The simulation system is a computer generated forces (CGF) system, and it can provide virtual air-raid forces as enemy for antiaircraft forces in air defense training. 该系统是一个计算机生成兵力系统，在防空训练模拟中为防御方提供作为敌方的空袭兵力，即虚拟靶标。
