结果表明：海水中的声速梯度以及海水深度失配是对定位精度产生影响的主要因素。
Result is indicated: Sound velocity grad and seawater depth loss be qualified for in seawater is the major factor weighing to allocation accuracy.
本文首先把能够到达接收器的那些简正波按能量相加，然后对发射深度与接收深度进行平均，导出了负声速梯度浅海中平均声强的表式。
The normal modes which can arrive at a receiver are summed according to energy, and an expression for the averaged intensity is then obtained by averaging over the source and receiver depth.
