The third, since the electrons in the plasma are accelerated and ions move together, some harmful effects are also observed, such as both output powers of RBWO and FEL decrease versus the increase of plasma density. The results agree with the results of linear fluid model. In the unmagnetized plasma-loaded RBWO-FEL, output powers of pump source and FEL are obtained only in a narrow plasma density range and both have maximum. The results of simulation are in good agreement with the experimental results.

模拟分析了磁化等离子体填充的RBWO-FEL，尽管没有发现等离子体填充后RBWO及FEL输出功率的成倍增长，但是观察到等离子体的引入对RBWO-FEL产生以下影响：泵波及FEL的辐射频率的线宽得到明显增加；在较高的等离子体密度下，TM〓模将会被完全抑制；首次观察到T-G模振荡及功率输出，结果同线性理论计算结果基本一致；等离子体中的电子被加速及背景离子的移动将对器件工作产生不利影响。

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 results show that concentration of ownership has a significant impact on risk-taking. The higher the largest shareholder's shareholding percentage, the higher the risk-taking is; the higher the top five shareholders' shareholding percentage, the lower the risk-taking is. The percentage of untradeable shares, the size of the board of directors, the proportion of independent directors and the average remuneration of top 3 senior executives with the highest remuneration are negatively correlated to the risk-taking. However, the situation that the chairman or vice chairman concurrently holds the post of president or CEO increases the bank's risk exposures to a certain extent. Proportion of state-owned shares, the nature of the largest shareholder and the executives' shareholding have no significant impact on risk-taking.

结果表明，股权集中度对风险承担产生了显著的影响，其中第一大股东持股比例越高风险承担越高，而前五大股东持股比例越高风险承担越低；非上市流通股比例、董事会规模、独立董事比例以及薪酬最高的前三名高管的平均薪酬均与银行风险承担负相关；银行董事长同时兼任行长在一定程度上倾向于增加银行的风险承担；国有股比例、第一大股东性质和高管持股状况没有对风险承担产生显著影响。

In order to analyze the reason for a flawed Iraqi identity, this article delaminates the internal identity of Iraq to two levels——national and sub-national, further distinguishes familial identity, religional identity and ethnic identity on the sub-national level, and studies the relations between national and sub-national identities with looking back at the momentous events in Iraqi history, consequently finds the different influences that various of sub-national identities react on the formation of Iraqi national identity and how the discriminative internal policy intensified sub-national identities, and then builds a theoretical framework with two dimensions from upwards and downwards to explain the reason for unshaped Iraqi national identity.

为了分析伊拉克国家认同没有形成的原因，文章将伊拉克内部认同在国家和次国家两个层次上进行划分，并进一步区分了次国家认同中的家族部落、宗教派系、族群这三个认同类型，然后以国家认同和次国家认同的关系为切入点，研究了伊拉克历史上的几个重大事件，发现了各次国家认同对国家认同的形成具有不同程度的影响，其中族群认同对国家认同形成的破坏作用最大；与此同时，伊拉克前政府歧视性的内部政策强化了各次国家认同，是造成伊拉克国家认同没有形成的另一个原因，从而从上、下两个维度解释伊拉克国家认同未形成原因的理论架构。

The values of D10 and D for the total bacteria in boiled dumplings under chill state were 2.04 kGy and 4.00 kGy, the value of D10 and D for E. coli were 1.25 kGy and 2.00 kGy. TBAS were increased significantly and excessed the trade standard by 5 kGy γ-irradiation. However, the TBAS would be decreased with addition of antioxidants. Lipid peroxide,volatile basic nitrogen,"a" value of color and "b" value of color showed a tendency of increase, and moisture content and Aw showed a tendency of decrease, which did not achieve a significant level(p.05) by 1 to 5 kGy doses of γ-irradiation. Total acidity, amino acid nitrogen and free fatty acid showed no significant differences between treated and control samples. Sensory evaluation values were decreased and were all well within the acceptable level by 1 to 5 kGy doses of γ- irradiation.

The influencing effects of grain production systems on the population of second generation of cotton bollworm in cotton were studied. The multi-harvest system provided cotton a good protection against cotton bollworm due to the corn plants in this system strongly attracted cotton bollworm adults when they were ovipositing, therefore reduced the density of cotton bollworm in cotton, compared with ton-grain system..
