We reconstruct the dynamic images using the data measured from our physical phantom . the bfgs variable metric method is nonsensitive to noise , the result background is even on the whole . the objects in the images are clear 基于物理模型的实测数据的成像结果表明： bfgs变尺度法抗噪性能较好，图像的背景比较均匀，目标清晰；目标图像的大小与实际大小接近，定位较准确。
The main problem is that near shore , a tsunami ' s actual size is masked by additional waves generated as the tsunami bounces off seawalls , wraps around islands , or sloshes back and forth in a bay ? all of which make for a very tangled signal 然而主要问题是当海啸接近岸边时，冲击防波堤产生的巨浪，或是当它包围岛屿、在海湾里来回所飞溅的浪花，都会造成非常紊乱的讯号，掩盖海啸的实际大小。
