A Krylov space based time domain method for wave propagation problems is introduced. The proposed method uses the Arnoldi algorithm to obtain broad-band frequency domain solutions. This method is especially advantageous in cases where slow convergence is observed when using traditional time domain methods. The efficiency of the method is examined in several test cases to show its fast convergence in such problems.

高速列车运营经济性是高速铁路运营经济性和可持续发展的重要参考指标。而高速列车运行能耗是高速列车运营经济性的重要影响因素。在分析高速列车全寿命周期成本的基础上，分析了高速列车运营能耗构成及其各部分能耗占比，进一步提出了高速列车运行能耗模型，在此基础上分析了各部分能耗的占比和影响要素，并给出了高速列车节能降耗的提升方向，为高速列车节能减排提供借鉴。 The operating economy of high-speed train is an important reference index for high-speed railway operating economy and sustainable development. The running energy consumption of high-speed trains is an important factor affecting the economy of high-speed train operation. On the basis of analyzing the life cycle cost of high-speed train, this paper analyzes the composition of energy consumption of high-speed train operation and the proportion of its energy consumption, and further puts forward the model of high-speed train running energy consumption. On this basis, the paper analyzes the proportion and influence factors of the high-speed train, and gives the upgrading direction of energy saving and consumption reduction of high-speed train and provides references for energy saving and emission reduction for high-speed train.
