We developed a new left atrial model to simulate intra-atrial flow and a simple method to observe atrial vortex by magnetic resonance imaging (MRI).A flow simulation model of the left atrium (LA) was developed based on slices of the LA image acquired by 1.5T MRI scanner system.Images were reconstructed by commercial software and a computational model was created by using tetrahedral mesh.In order to give the model consecutive temporal change,we presumed that deformation of the LA is related to mitral valve annular movement.

摘 要：随着经济的飞速发展，输电线路总长度和传输容量不断增长，同时，对输电线路运行的安全性和可靠性要求也越来越高。本文通过实际运行经验，对输电线路雷害原因进行分析，影响雷害的因素是多方面的，根据雷害故障的性质以及线路运行情况，考虑现场地理情况，提出了一些有针对性的防雷措施。 关键词：雷击跳闸；防雷措施；输电线路运行 0引言 输电线路是电力系统的重要组成部分。由于它暴露在自然之中，故极易受到外
