在特征选择阶段，采用计算近似增益的平行算法，解决模型计算量过大和系统开销问题。
In the feature selection stage, the computing approximate gains in parallel is adopted in order to solve the computational expensiveness of the model and system spending.
考虑在主轴上放置透明盘片，用PSD测量位移子系统测出放置透明盘片前后的光斑移动距离，就可以计算出光头与主轴马达间的平行度。
Using the transparence CD, PSD can detect the displacement of laser spot between non-placing and placing the CD, and it can be used to calculate the parallelism between optical head and spindle motor.
