The results indicated: 1 .There is obvious difference between the gonads of precocious and unprecocious fish: in female, the ovaries of unprecocious fish stay in 141 stage, and are mainly consisted of oogonias and early oocytes; the ovaries of precocious fish have developed into IIIAV stage, most of the oocytes are in the large growth stage.

ResultsFracture did not reach anatomical repositioning, improper selection and placement of the implant, unpromptly nonunion treating, long time placing of the implant, inappropriate functional exercise postoperation, premature loading were the main reasons for implant rupture.

结果：骨折未达到解剖复位，内固定物选择及安放位置不当，未及时治疗骨不连，内固定物放置时间过长及术后不适当的功能锻炼、过早负重，是造成内固定物断裂的主要原因。

However, a kind of saturable absorption effect has been introduced in unpumped EDFA based on the absorption of the Erbium system which means a lower absorption coefficient in higher intensity.

但是未泵浦的EDFA由于铒离子系统的吸收作用存在一种饱和吸收现象，这种饱和吸收作用使得未泵浦的EDFA在一个高光强下有很低的吸收系数。

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 powder baked at 680C is perfect in properties, and zinc oxide will decompose when the reduction temperature exceeds 700 C,Results of XRD, SEM and TEM for the targets indicate that secondary phase ZnAl2O4 exists in the targets synthesized with reduced or unreduced compound powders, but not in the target synthesized with nanometer powders.
