With the algorithm, the current state of maneuvering target can be estimated directly and correctly without assuming the model of maneuvering acceleration.

该算法不需要假定目标的机动加速度模型，而是直接正确地估计出机动目标的当前状态，不存在任何估计滞后与修正问题。

Because the utility model adopts the form of electron-acceleration of ion-ion bonding so as to cause ion flow collected by a base plate (a workpiece) is only 10 to 15 percent of target current.

由于本实用新型偏压采用电子—离子加速—离子结合形式，使基板(工件)所收集到的离子流是靶电流的10—15%。
