同时我们还发现，在一定条件下，晶体损耗能使振幅失配的高斯光束演化成匹配的高斯光束，并最终演化成稳定的明孤波。

It is found that the loss in the crystal can make a mismatched incident Gaussian beam evolve to a matched one, and then become to a steady-state bright soliton.

通过分析光纤熔接损耗产生的原因，得出可以调整熔接参数来改善模场失配，实现不同类型光纤的低损耗熔接。

Then the mode distributions at the fiber tips and the corresponding splice loss between the two fibers were calculated, and the fusion power range for low splice loss was thus deduced.

本文介绍一种测量低损耗互易二端口网络在较大失配情况下的功率传输效率的测试系统。

This paper describes an accurate method for measuring the efficiency of low loss reciprocal two-ports network under larger mismatch.
