考虑到光纤出射光束的发散，在有效反射率中引入了损耗因子，讨论了它的基本工作原理。

Its principle is discussed, taking the divergent optical beam emitted from the fiber into consideration, which causes a loss factor for the effective reflectance.

海底的冲淤格局与泥沙输运场中输运率的聚合或发散状况一致。

The seabed erosion - accretion pattern is consistent with the situation of convergence or divergence of sediment transport rate.
