The DB and ULF accelerations are expressed in terms of arbitary time-dependent forces acting on the heart and on the body frame. For an appropriate choice of these forces, a normal DB and ULF and acceleration Bcg is reproduced. By reducing the coupling, between the subject and platform, the DB Bcg is changed successively until it is identical with the ULF Bcg.
DB和ULF加速度是根据作用于心脏和身体坐标系上的任意随时间变化的力来表示的。对于这些力的适当选择,可以再现正常的DB和ULF以及加速度Bcg。通过减少受试者与平台之间的耦合,DB Bcg会连续变化,直到与ULF Bcg相同。
