对电路板的图像进行分割，可以提取电路板中的目标物，以对电路板进行检测。文章使用K均值聚类算法完成对电路板图像的分割，针对传统的K均值聚类算法的不足，提出了使用直方图波形的有效波峰个数来确定K值的大小，并通过使用一种比传统的绝对误差的表示更简洁的表达式，达到了快速分割的目的。对一些电路板图像分割的实验结果表明，文章的方法能够根据目标物的数目有效的确定K值的大小，且比传统的K均值算法减少了运算量及计算时间。
(On the circuit board image segmentation, to extract the target board to the circuit board for testing. Article using the K means clustering algorithm to complete the circuit board image segmentation, the traditional K-means clustering algorithm, the paper proposes the effective use of histogram peak wave number of K values to determine the size, and by using a ratio of absolute error of the traditional expression that is more concise, to the fast segmentation. For some circuit board image segmentation results show that the method can be according to the article the number of valid target value to determine the size K, and K-means algorithm than the traditional reduced computation and computing time.)

简单潮流计算的小程序，相关的原始数据数据数据输入格式如下： B1是支路参数矩阵，第一列和第二列是节点编号。节点编号由小到大编写 对于含有变压器的支路，第一列为低压侧节点编号，第二列为高压侧节点 编号，将变压器的串联阻抗置于低压侧处理。 第三列为支路的串列阻抗参数。 第四列为支路的对地导纳参数。 第五烈为含变压器支路的变压器的变比 ( Simple little program flow calculation, the raw data of the data related to data entry format is as follows: B1 is the slip parameter matrix, the first column and second column is the node number. Node number from small to big with the transformer for the preparation of slip, the first as the low pressure side of the node number, the second as a high-pressure side of the node number, the series impedance of the transformer low voltage side of the deal placed. As the third branch of the serial impedance parameters. Fourth as a slip of the ground admittance parameters. Strong as with the fifth branch of the transformer transformer turns ratio )
