Originating in the volt-ampere relationship of the general branch, the author of this paper formulates the loop matrix equation and cut-set matrix equation of a linear network without the resort of shifting the ideal sources voltage and current source or independent and dependent source. 本文从电路一般支路的伏安关系出发,不转移理想电源支路包括独立电源或受控源,电压源或电流源导出了线性网络的回路电流矩阵方程和割集电压矩阵方程。
People's exploring on the recognition of knowledge network is a spiral development process originating from network and ending with network, from the outwards ( bibliography network) to inwards ( network space structure of knowledge itself). 人类对知识网络认识的探索是始于网络并终于网络、由表(文献网络)及里(知识本体的网络空间结构)的螺旋上升的认识发展过程;
Because the gas transportation and distribution network system in Northwest Originating of Xinjiang not only has a function of gas transportation, but also has a function of gas distribution, so the gas storage and peak adjusting of the pipeline network system were studied in this dissertation. 由于西北缘输配气管网系统兼有输气和配气的功能,因此,本文对该管网系统的储气和调峰进行了研究。
