In this paper, by using the method of geometrical optics and the theory of fiber optics mode, we analyzed difference characteristics of double-clad fiber andthe effect of all kinds of DCF's inner-cladding structures on1 the absorption efficiency of DCF and its laser.

因此在本论文里采用几何光学和纤维光学模式理论的方法分析了不同内包层结构的双包层光纤对光纤激光器性能的影响，建立理论分析模型，并设计了新型内包层结构的双包层光纤。

I had a short Jacket of Goat-Skin, the Skirts coming down to about the middle of my Thighs; and a Pair of open-knee'd Breeches of the same, the Breeches were made of the Skin of an old He-goat, whose Hair hung down such a Length on either Side, that like Pantaloons it reach'd to the middle of my Legs; Stockings and Shoes I had none, but had made me a Pair of some-things, I scarce know what to call them, like Buskins to flap over my Legs, and lace on either Side like Spatter-dashes; but of a most barbarous Shape, as indeed were all the rest of my Cloaths.
