In the traditional AdaBoost method,the weights are updated based on the weak classifier's overall error rate, this article proposes one kind of the method which unifies the level of difference between the threshold and the feature value of the weak classifier with the weak classifier's overall error rate. Compared to the method which only based on the overall classification error rate to update the weights,this method can achieve higher detection rate while reduces the mistaken-detection rate.

在传统AdaBoost方法中，权重是根据弱分类器的整体错误率来更新的，本文提出了一种将弱分类器的阈值与特征值相差程度和弱分类器的整体错误率相结合来更新样本权重的方法，相比较只根据整体分类错误率来进行权重更新的方法，这种方法可以在降低误检率的同时达到较高的检测率。

通过实验和仿真可以看出，摩擦阻碍了转台电液位置伺服系统商精度控制的实现，任何一个框架的运动都会对其余框架的伺服驱动系统产生干扰力矩并引起伺服系统误差，反馈测量元件的分辨率误差和安装误差直接反映在伺服系统输出上，对伺服系统的精度有直接影响。

Then the error sources of the reaction type and electron type electric energy mete were analyzed and the theory analysis result through the concrete test have been proved. At last, the main conclusion has been drawn. When the induction type electric energy meter measures harmonics energy, the negative error characteristic appears. The higher the frequency of harmonics is, the greater the error is. The electron type electric energy meter can measure harmonics energy accurately in general cases. Except thermo-electrical conversion type electron type power meter, reaction type and electron type electric energy meter can measure direct current power.
