According to the characteristics presented by armed helicopters during cruising or searching for ground targets, this paper has established the mean-square deviation stationary random model of helicopter tracks. It is an important method to decorrelate the measure noise by estimating the parameters of the color noise online. Kalman filtering and forecasting have been made with helicopter tracks. The simulated study has been carried out on helicopter tracks under the condition of color noise. It is very difficult to get an accurate and reliable prediction when the data is very limited. The paper make use of the theory of grey system to resolve the problem of prediction of helicopter tracks, establishing the GM model of grey systems and the cumulative residual error model of n degree, then correcting the GM forecast model. In the period of sampling, GM model and residual error model have been established on line to improve prediction precision.

结合武装直升机在巡航或搜索地面目标的特点，给出直升机航迹模型为协方差平稳随机模型，在线估计有色噪声参数，对测量噪声去相关，对直升机航迹进行卡尔曼滤波与预估，最后对有色噪声条件下的航迹进行了仿真研究；在数据非常有限的情况下，准确地预测又很困难，本文提出了用灰色系统理论解决直升机航迹预测问题，建立了灰色系统GM预测模型和n次累加残差模型并对GM预测模型进行修正，在每个采样期间内，实时在线建立GM预测模型和残差模型以提高预测精度。

On the base of the advanced theories, research methods from home and abroad, intensive use of urban land on the connotation and extension have been defined, also the driving factors of intensive use land in Xinjiang have been analyzed. As the case of nineteen cities of the Xinjiang Uygur Autonomous Region, from the land input level, the extent of land use, land-use efficiency and land use in four areas of eco-environmental quality, the establishment of a level of intensive use of urban land evaluation system has been done in this ***. Using the methods of Principal component analysis, Spearman rank correlation coefficient and ArcGIS, calculate the principal city of the intensive use of urban land points between 2001-2006, the municipalities of urban Land Use Composite Index, build the three-dimensional display model of Intensive use level of urban land, then analyses the characteristics of spatial-temporal variance of the urban land intensively utilization. Finally, analysis propose measures and advices.

Many researchers have devoted their work to the development of modal analysis extraction techniques in order to obtain more reliable identification of the modal parameters. There are many damping identification methods, but each one has different merit and defect. In order to find which one is the most reliable method with respect to certain characteristics, this thesis focus on how to identify structure's damping in time domain. The following works have been done in this thesis: 1. Investigate four modal analysis methods——the LSCE Method, the Ibrahim Time Domain Method, the Time Domain Collectivity Modal Parameter Method, the Rational Fraction Polynomial Method and improve on the ITD Method in arithmetic.

本文主要做了如下工作： 1、集中研究了四种常用的模态识别方法，即最小二乘复指数法、Ibrahim时域法、时域总体模态参数辨识法及有理分式多项式法，并对ITD法在算法上进行了一定的改进； 2、建立结构动力模型，利用这四种方法在具体条件下识别结构的阻尼，并绘制相应的图； 3、讨论不同的情况下，不同的识别方法对阻尼识别精确性的影响； 4、基于业已明确的阻尼识别的精确性，根据研究的需要，指出在实际的识别过程中，如何选择最佳的识别方法以及识别过程中需要注意的问题； 5、选择最为精确的阻尼识别方法，以导师李书进教授在日本京都大学防灾研究所强震反应实验室所做的一足尺木制结构房屋的动力测试实验为实测模型，识别其阻尼； 6、在本文的最后，尽作者所知，提出了一些需要改进的地方，并对未来的研究方向给出了作者的建议。

Through correlative analysis and path analysis, it finds that (1) the family environment and the colleges and universities environment have direct and indirect influence on self-identity development of students; and (2) the family environment and the colleges and universities environment exert the major effect on self-identity development of students through identity style as mediational variable, so identity style becomes the explanatory base of self-identity status. That is, the predictive effect of diffuse/avoidant identity style for identity diffusion, normative identity style for identity foreclosure, and information identity style for identity achievement respectively is most significant; and (3) family environment that is helpful, supportive, warm, expressive, and promote autonomy and independence possibly makes students form identity achievement or identity moratorium, family environment that is excessively cohesive and warm but lacking independence possibly promote students to form identity foreclosure, and family environment that lacks of supportive and warm possibly make students form identity diffusion; and (4) colleges and universities environments that have better relationship system, clear developmental purpose, and promote to pay attention to societal concerns, critical and explorative qualities, and provide healthy, expressive, democratic, open atmosphere facilitate identity development, in turn form advanced identity. Colleges and universities environments that only emphasize the receival of colleges and universities aims, order and instilments, and scarcely encourage critique, exploration, individuation possibly make students form identity foreclosure. However, the ones that is remote relationship system, and lacking support, and students don't cognize the aim of colleges and universities possibly make students form identity diffusion.

通过相关分析、路径分析发现：(1)家庭环境和学校环境对大学生自我同一性有直接和间接的影响；(2)家庭环境、学校环境对大学生自我同一性影响主要以同一性加工方式为中介变量，同一性加工方式成为自我同一性状态的解释基础，弥散—回避定向同一性风格对弥散型同一性预测力最大，信息定向同一性风格对成就型和延缓型同一性预测力最大，常规定向同一性风格对排他型同一性预测力最大；(3)相互支持、帮助、关心、自由表达和鼓励自主和独立的家庭环境促进大学生同一性的发展，形成成就型或延缓型同一性状态，过度亲密而缺乏独立性特征的家庭环境可能形成排他型同一性状态，而缺乏支持性，关系疏远的家庭环境可能形成弥散同一性状态；(4)良好的关系系统，明确的发展目标，鼓励学生对社会事务关注、倡导批判和探索精神，塑造良好、健康、可供自由表达、民主、开放的文化氛围的大学校园环境促进大学生同一性发展，形成高级、成熟的自我同一性，而一味强调学校目标的接受，强调秩序、灌输，缺乏对批判、探索、个性发展鼓励的学校环境有可能使学生形成排他型同一性状态，但若学校的关系系统疏远，缺乏支持性的民主的风格，目标不能被学生明确感知的学校环境则可能影响学生形成弥散型同一性。

There are a number of reasons why you should consider taking a dietary supplement. For a start, few of us eat an adequate amount of phytochemically-rich fruits and vegetables each day. Phytochemicals have been shown to have a positive impact on reducing the risk of degenerative diseases, but most people consume a very limited selection of good foods on a regular basis.The fact is that variety in your diet is important to guarantee you get enough of the 45 known essential nutrients that maintain the body's health.

人体需要营养补充品的理由有很多，因为只有小部份的人能够从日常饮食中进食充足份量含丰富植物化学素的蔬果，而大部份人会惯常地食用某几类食物，但选择不同种类的食物是很重要的，这样才可确保人体得到45已知的必须营养及多种重要的植物化学素，这些都证实有效减少变性疾病。
