After three years' spring fishing off, dominances of the main species decreased, CPUE of part reaches increased, and Margalef diverdity index, Pielou evenness index and Wilhm Modified Shannon-Wiener diversity index of the three reaches showed the rising tendency, which indicated the richness of species number and complication of community structure, and the positive ecological effects by the spring fishing off.

春禁后，渔获物主要种类优势度有所下降，部分江段单位捕捞努力量渔获量表现出一定上升趋势，3个江段Margalef指数、Pielou指数和Wilhm改进指数有一定升高，表明种类丰富度有所提高，群落结构趋于复杂，春季禁渔有一定效果。

Therefore, the study is significant both theoretically and practically. As a result, the studying aim of this paper is to establish a practical and complete system for the prediction of ship maneuvering motion, taking into account of the influence of the environmental factors, such as the wind, wave and current, establish a practical and complete system for the prediction of ship maneuvering motion. In this paper, the OpenGL virtual reality simulation technique is introduced into the field of ship maneuver and control, and using the MMG mathematical model, the three dimensional dynamic simulation system of the ship motion is established and good results are achieved. In the process of the system development, firstly, the maneuvering motion equations for ship in the still water are established, based on the MMG module mathematical model and serial experimental result. After compiling the program, the calculation results are compared with the experimental data, the coherence between them validate the mathematical model.

在系统开发过程中，首先采用MMG分离式数学模型及相关的系列化试验结果，建立单桨单舵海洋运输船舶在静水中的船舶操纵运动方程，并编制计算程序，经与试验结果比较，证实了计算结果的正确性；为了解MMG数学模型中模型参数变化对操纵性指数的影响程度，作者在上述已有程序基础上，对有关模型参数进行偏移修正，探讨了相应参数变化后的操纵性指数，对船舶操纵性指数对模型参数的灵敏度进行了详细的分析与探讨，所得结论与工程实际相吻合，具有实际应用价值，并为进一步提高船舶操纵性预报的精度打下了基础；然后，在已有的船舶静水操纵运动模型基础上，考虑双桨双舵的影响，建立了内河双桨双舵船舶的操纵运动模型；最后，综合考虑风浪流作用力的影响，进行了船舶的操纵运动仿真计算。

Results: The peak responses of postprandial glucose and C-peptide were postponed; their values and the incremental area under curve of glucose responses of gruels were obviously lower than that of steamed bun (P.05). While both glycemic index and C-peptide index of steamed bun were set as 100, the glycemic index and C-peptide index of gruel A were 67, 99, and of gruel B were 57, 97 in NIDDM patients, 53, 69 in healthy subject.

结果 1。三组餐后血糖、C肽峰值显著低于馒头，血糖反应增值面积有显著性差异，以C组最低，A组最高；2.A、B两组C肽曲线增值面积显著低于C组；3.A、B、C三组血糖、C肽指数分别为67、99，57、97和53、69；4.B、C组血糖指数显著低于A组，C组的C肽指数明显低于A、B组。

Because there are three different criteria for such status—income per head, a human assets index comprising health, nutrition, literacy and school enrolments, and an economic vulnerability index (which uses various measures to assess a country's exposure to natural and climatic setbacks)—the data, based on figures for income per head, give no more than a broad indication of graduation timetables.

因为对这些身份而言有三项不同的标准——人均收入、由健康、营养状况、读写能力和入学年纪构成的人均资产指数，以及一项经济脆弱指数（这个指数在评估时使用了大量措施，将一个国家自然环境和气候环境的恶化暴露出来）这些数据，基于人均收入的指标，提供的仅仅是一个毕业时刻表的宽泛指示。

In order to make the uncertainty of the dose index measurement in the head phantom reasonable for the medical diagnostic X-ray radiation sources of the computed tomography, the measurement uncertainty components were analyzed according to the mathematical model for the computed tomography dose index test method with a 100 mm ionization chamber.

摘 要：为了使医用诊断计算机断层摄影装置X射线辐射源在模体中的剂量指数测量结果的不确定度评定合理，基于用带有100 mm长杆电离室的积分剂量仪测量CT剂量指数的数学模型，对其测量不确定度来源进行分析，列出了方差、灵敏系数及标准不确定度的计算公式，从而给出了CT剂量指数测量的合成标准不确定度和扩展不确定度。
