Nonlinear loads are reduced by current sink reduction ( CSR) method, which means nonlinear loads are expressed by current sinks and reduced by Gauss reduction method. 非线性负荷节点的化简采用的是电流穴简化法,该法是把高斯消元法推广到处理非线性负荷,用恒定电流沟近似表达负荷。
According to the demand of engineering surveying, With the theory of geodesy and the method of gps network adjust, This paper discusses how to minimize the scale error of gauss projection and datum plane reduction by changing the side scale when we adjust the engineering gps network. 根据工程勘测的需要,应用大地测量学及GPS网平差理论,结合实例,探讨运用边长尺度比来有效消除GPS网平差中高斯投影及高程归化变形的计算方法。
