filt怎么记

Fe nano-films are deposited on pure Si wafer by arc filtered deposition ( AFD ) system.

采用弧过滤离子沉积系统 ( arcfiltereddeposition, AFD ) 在纯硅表面制备铁纳米薄膜.

Comparing to the Extended Kalman Filter ( EKF), the lo-cation effect is better when the proposed algorithm is applied to the single passive location.

将改良后的UKF滤波算法应用到单站无源定位的测向法中，得到优于The Extended Kalman Filter（EKF）滤波的定位效果，大大提高了定位精度。
