Many new detection techniques are proposed, that include: To overcome the faults of cross-terms and short unambiguity range for the common Wigner-Ville Distribution , short-time Fourier transform and Gabor transform are applied to SAR moving target detection. To improve the detection performance of WVD in noise environment, a new technique based on the Cross-WVD is proposed. The application of fractional Fourier transform to chirp signal detection is analyzed and extended to SAR moving target detection. To eliminate the restriction of chirp-Fourier transform, a new modified definition is proposed and applied to SAR moving target detection. To detect multiple moving targets whose scattering intensities are different heavily, the CLEAN technique is combined with the above techniques and the ideal detection performance is achieved. At last, the whole dissertation is concluded.

具体的研究成果如下：针对常用的Wigner-Ville分布在多目标情况下存在交叉项，并且多普勒不模糊范围小的缺点，提出将短时Fourier变换和Gabor变换应用于SAR运动目标检测，分析了其优势所在；为进一步提高Wigner-Ville分布低信噪比条件下的信号检测能力，提出基于互Wigner-Ville分布的运动目标检测方法；分析了分数阶Fourier变换在线性调频信号检测中的应用，提出基于分数阶Fourier变换的运动目标检测算法；对离散Chirp-Fourier变换的定义进行了修正，提出修正的离散Chirp-Fourier变换，克服了限制其应用的约束条件，并用于SAR运动目标检测当中；强度相差较大的多运动目标检测历来是机载SAR技术的一个重点和难点，我们将CLEAN思想融入上述多种算法当中，良好地解决了该问题。

In this study, the methodology of linear structural rela- tionship model of latent variable has been studied which is the first time in China. Some extended conclusions have been come up to, such as multi-factor congeneric measure model, the reliability of measurable variable and its hy- pothesis test, the relation between standardized solution and unstandardized solution, multidimensional path model with measure errors, and multilevel model of latent vari- able. Some examples have been shown to help apply these results in practice, such as the analyses of the children growth-development data, the bone density data and the health resources data by means of latent variable model. Not only have new explanations for these data been achieved, but also powerful patterns for applying the theoretical methods in medical sciences and other fields.

首次系统地研究了潜在变量的线性关系模型，对部分已有的结论作了有益的推广，如：多因子度量模型、观测变量的可靠性及其假设检验、标准解与非标准解的关系、有度量误差的多维通径模型、以及多水平资料的潜变量建模；并用实例阐述了它们的具体应用，如分析了儿童发育调查资料、人体骨骼密度调查资料以及卫生资源利用效益评价资料，不仅获得了这些资料本身一些新的解释，也为本文所研究的理论方法在医学科研以及其它领域科研中的应用提供了例证，也便于广大医学工作者掌握。

An article widely carried on state media websites said the contest had caused Chinese intellectuals to "fantasise about arrangements for democratic elections and notice the awakening of democratic consciousness among the younger generation."

一篇在主要网站上被广泛转载的文章指出，这场娱乐性的比赛已经促使中国知识分子&憧憬民主选举的具体操作方式，并且同时欣喜地感受到年轻一代民主意识的觉醒……&当然，正统的《中国日报》对此相当不以为然，它质疑道：&模仿民主的形式，最后选出来的歌手却连音都唱不准，这不是很奇怪吗？&

Hence the need for a flexible interpretation of the guidelines to INDIVIDUALISE therapy to suit the circumstances of each patient.

Science and technology has greatly improved in the material standard of living and improve the meantime , We also brought to the original unanticipated confusion : material fruits such as when we are not all the desire to go faster pace workplace and narrow enough between people , the pressure of life and survival for all competition is so specific and practical .

科学技术在极大地改善和提高物质生活水平的同时，也给我们带来了原本不曾预料的困惑：物质文明成果所带来的一切并非如当初我们的渴望，奔波于快节奏工作场所和狭窄蜗居之间的人们，生活的压力和生存的竞争使一切都是那么具体而实际。

The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出，每个树种在树冠内相对高度上的叶量的垂直分布是不同的，天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小，约占10%左右；在树冠的中部以及中下部(0.4CL～0.8CL)，叶量所占比例最大，几乎集中了整个树冠60%～75%的叶量；而在树冠的下部(0.8CL以下)，几乎占很少的叶量，大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系，并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木，并不是传统意义上的全部竞争木；本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况，并采用等树冠投影面积法把树冠分为5级，这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想，用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型，设计了10个与林学意义相一致的约束条件，并采用0-1整数规划的思路，在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例，具体计算出了每株采伐木，经过择伐后，目标函数值按模型设计的要求发生了极大的改变，增加了5倍多，说明了最后这个解的优良性，满足了设计的要求。
