The research which is the important part of the tunable erbium-doped fiber laser is composed of two main parts: 1. the gain part of the tunable erbium-doped fiber laser, which in fact is an erbium-doped fiber amplifier, its output characteristics are discussed both in theory and experiment, and the differences are also discussed between theory and experiment; 2. the saturated absorber part of the tunable erbium-doped fiber laser, also the part to narrow the line width of the fiber laser. The line-width narrowing mechanism in fiber laser induced by unpumped Er-doped fiber is presented from the aspect of coupling wave equation, and the main factor is considered as the standing wave induced by interference. The line-width is narrower when the standing wave is stronger, and the narrowing effect disappears with the disappearance of the standing wave. In the experiment, when adding a Faraday mirror in the laser cavity to remove the standing wave , the narrowing effect disappears. So the theory is proved by the result of the experiment.

本课题的研究内容是集成光学声光可调谐掺铒光纤激光器的重要组成部分，主要分两部分：1、声光可调谐掺铒光纤激光器中增益部分的研究，相当于对掺铒光纤放大器的研究，理论上对掺铒光纤放大器的输出特性进行分析，实验上实现了掺铒光纤放大器系统，并将实验数据与理论计算数据进行对比，分析了误差产生原因；2、声光可调谐掺铒光纤激光器中饱和吸收体部分的研究，即压窄光纤激光器输出线宽的研究，从耦合波方程出发，理论上解释了未泵浦掺铒光纤压窄光纤激光器线宽的原理，分析了影响该作用的主要因素是未泵浦掺铒光纤中相对传输的光干涉形成的驻波：驻波越强，压窄效果越好，相反当没有驻波时，没有压窄效果，在实验上通过在激光器腔内加入法拉第旋转镜使驻波消失，同时压窄效果消失，从而验证了理论分析的正确性。

The cases with osteophyte formation were classified into 3 groups: osteophyte formation with disc height narrowing (n = 217), osteophyte formation without disc height narrowing (n = 99), and control group defined as the cases without osteophyte formation (n = 71). Twele genotypes were characterized.

骨赘形成的病例分为3组：骨赘形成伴椎间盘高度减小（n＝217）；骨赘形成不伴椎间盘高度减小（n＝99）；和对照组－确定没有骨赘形成（n＝71）。12种基因型具有特征性。

Rectal narrowing, thickening of the wall, and increased presacral space are typical in chronic ulcerative colitis and are well depicted at CT (Fig 4). These features result from the mural thickening, rectal narrowing, and proliferation of fat.

直肠狭窄壁厚以及骶前间隙扩大是慢性溃疡性结肠炎的典型表现，而且CT 能够很好的显示，这些表现来源于肠壁增厚、肠腔狭窄以及脂肪增生

与narrowing相关的网络解释 [注：此内容来源于网络，仅供参考]

narrowing：缩小

跟词义扩大相反,原来的词义可以缩小(narrowing)或限制到一个明确的意义上. 例如,meat在17世纪的意思是"食物",但是现在它的意义限制为"肉、肉类". 下面有更多的例子. 所有的语义变化都涉及到词义的转移. 这里的词义转移(meaning shift)要从狭义的角度来理解,

narrowing：窄化

例如,TINYINT的值范围是从-128 到DECIMAL(不带小数点)在内部都是完全可以互换的,不存在数据窄化(narrowing)的情况. 根据不同的操作数类型,返回的操作结果是以任何相关的Java类型(Integer,进行除法运算时,DOUBLE和DECIMAL类型间的区别就显得很重要的.
