快速排序的基本算法-basic Quick Sort Algorithm

可以分析星历数据并解算出所需要的数据，生成天顶视图(It can analyze ephemeris data and calculate the data needed to generate zenith view.)

此为数字逻辑书上的答案，应该很多同学都需要吧，关于数字逻辑(This is the answer books, digital logic, it should be a lot of students need it, on the digital logic)

飞利浦LPC2114中文手册，是学习ARM的好资料。(Philips LPC2114 English manual, is to learn good information on ARM.)

atmega64接口与atmega128接口的具体应用，注明与标准的ISP接口的区别-ATmega128 interfaces atmega64 interface with specific applications, annotated with the standard interface of the ISP the distinction

电力系统潮流计算体现在数学就上是多元非线性方程组的求解问题，求解的方法有很多种。牛顿—拉夫逊法是数学上解非线性方程式的有效方法，收敛性好、迭代次数少。将牛顿—拉夫逊法用于潮流计算是以导纳矩阵为基础的，由于利用了导纳矩阵的对称性、稀疏性及节点编号顺序优化等技巧，使牛顿—拉夫逊法解题规模和计算速度进一步提高，此算法至今仍是潮流计算中广泛采用的优秀算法。(Power flow calculation in power system is a problem of solving multivariate non-linear equations in mathematics. There are many methods to solve it. Newton-Raphson method is an effective method for solving nonlinear equations in mathematics. It has good convergence and fewer iterations. The application of Newton-Raphson method to power flow calculation is based on admittance matrix. Because of the use of symmetry, sparsity and optimization of node number sequence of admittance matrix, the scale and speed of Newton-Raphson method are further improved. So far, this algorithm is still an excellent one widely used in power flow calculation.)

说明：  无限制版，极影工作室的看家产品之一，交易两个货币兑进行对冲。经过实际测试，EURUSD和GBPUSD的盈利效果最好，AUDUSD和NZDUSD不是很好。按理说这两组关联都不错才对，可能是测试期间行情所致，因为无法回测双币以上ea，实盘模拟测试。(One of the Housekeeping Products of Polarshadow Studio is trading two currencies to hedge against each other. After actual testing, EURUSD and GBPUSD have the best profitability, while AUDUSD and NZDUSD are not very good. It is reasonable to say that the correlation between the two groups is good, which may be due to the market during the test period, because it is impossible to retest the EA above two coins, a real-time simulation test.)
