充电宝的电路图，给想自己动手的同学们用来学习借鉴(the circuit of power bank)

说明：  电力方面配电网重构方面的资料，详细介绍了配电网重构的存在的问题，应用的方法，文章大多为硕博论文，比较详尽，是这方面学习的好资料(Electricity distribution network reconfiguration information, details of the distribution network reconfiguration problem, the application of the method, the article mostly papers, more detailed study in this regard the good information)

设计了一种新颖的三相锁相环的设计算法，可以用于不平衡电压的相位检测和跟踪。(A modified soft phase lock loop algorithm improving the performance inDynamic phase tracking and detection of unbalanced voltage)

一本关于介绍2015年发表的关于扩展有限元的SCI论文的论文集书籍，非常实用(In the standard FEM, cracks are required to follow element edges for the discontinuity modeling. In contrast, the crack geometry in the extended finite element method (XFEM) need not be aligned with the element edges and thus is independent of the background mesh.)

its the vhdl stuff for ddr sdram controller nice one easily understandable

a description for acoral(emcos)(2)

这是一个关于阴影检测的一种新的方法，论文发表在2013年pami上的，关于区域对来检测阴影( a new method about shadow detection ,using paired regions for shadow detection and removal)

QNMVD100系列高压变频器的使用说明手册。本产品的技术方案采用串桥级联多电平逆变器的主电路拓扑结构。高压变频器通过移相隔离变压器将三相6kV高压交流电，变换成3×5组错相的三相690V低压交流电，分别经功率单元整流、逆变、串联叠加形成0~6kV、0~50Hz的交流电压输出至异步电动机(QNMVD100 series of high-voltage inverter)

关于利用gnss反射测量技术对海洋进行遥感探测的博士论文，非常值得学习(On the use of gnss reflection measurement of marine remote sensing detection of doctoral thesis, is worth learning)
