本程序采用的是基于matlab的PQ分解法潮流计算，程序主要分为三个部分：第一部分用于生成系统的节点导纳矩阵。第二部分主要进行潮流系统的迭代运算。第三部分主要用于对程序最后输出结果的计算，如电压的幅值，相角，功率分布等。(This procedure is used in matlab the PQ decomposition method based on flow calculation, the program is divided into three parts: The first part of the node admittance matrix used to generate the system. The second part of the iteration trend system. The third part is mainly used for the calculation of the final output of the program, such as the amplitude of the voltage, phase angle, power distribution.)

Magnetic resonance (MR) images can be used to detect lesions in the brains of multiple sclerosis (MS) patients and is essential for diagnosing the disease and monitoring its progression. An automatic method is presented for segmentation of MS lesions in multispectral MR images. Firstly a PD-w image is subtracted its corresponding T1-w image to get an image in which the cerebral spinal fluid (CSF) is enhanced. Then based on kernel fuzzy c-means (KFCM) algorithm, the enhanced image and the corresponding T2-w image are segmented respectively to extract the CSF region and the CSF combining MS lesions region. A raw MS lesions image is obtained by subtracting the CSF region CSF combining MS region. By applying median filter and thresholding to the raw image, the MS lesions are detected finally. Results are quantitatively uated on BrainWeb images using Dice similarity coefficient (DSC). Finally, the potential of the method as well as its limitations are discussed.
