因此在实际使用中，巴特沃斯滤波器已被列为首选，用途十分广泛。
Therefore, in actual use, Butterworth filter has already been listed as the first choice, and used very widely.
低通滤波器可选用一定阶数和转折频率的巴特沃斯滤波器，而加速度计输出的转速补偿则须预先对加速度计进行标定。
The centrifugal force caused by rotation of drilling tool will distort the accelerometer outputs, which can only be revised by rotation speed compensation.
