FrequencyHoppingTechnology
在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案(The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program)

XFEM
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.)

TheDesignof35kVGridRelayprotection
本压缩包 包含 任务书、论文以及答辩ppt，虽说是课程设计，但是按照毕业设计书写，内容充实
本次课程设计主要是对象湖变的电网进行保护整定，对d1至d6共6个地方进行了最大方式与最小方式运行情况下的短路电流计算。计算完短路电流后，对L1至L5共5条线路进行电流保护整定。但是由于线路较短，线路阻抗较小。经计算后均不适合三段式电流保护。所以采取了纵联差动保护作为主保护，定时限过电流保护作为后备保护。对于变压器，采用纵联差动保护与气体保护共同作为主保护，过负荷保护作为后备保护。(The curriculum design is the object variable grid lake protection setting of D1 to D6, 6 places for the maximum and minimum operation mode under the condition of short-circuit current calculation. Calculation of short-circuit current after the end, L1 to L5 a total of 5 lines of current protection setting. But because of shorter lines, line impedance is small. The calculations are not suitable for three phase current protection. So take a longitudinal differential protection as the main protection, timing and limiting current protection as a back-up protection. For transformers, using longitudinal differential protection and gas protection as the main protection, overload protection as a back-up protection.)
