In order to empolder ocean resources and instruct engineering construction, this thesis synthetically analyzed regional geology, terrain, deposit sediments, hydrology, and sediments of coral reefs, have systemically studied the mechanical characteristics of calcareous sand and coral reef through indoor tests. 1. Many factors including regional engineering geology environment, hydrodynamic environment, terrain, physiognomy have been studied to evaluate their influence to coral reef engineering. It's considered that atoll reefs and table reefs are suitable for engineering construction and the reef flat on atolls is most perfect.

为了开发海洋资源，指导珊瑚礁工程建设，本文综合分析了南沙群岛区域工程地质特征、珊瑚礁地形地貌、海洋水动力环境、沉积物特征等资料，从工程地质角度对珊瑚礁各地貌单元的工程适宜性进行了评价，对礁灰岩和钙质砂进行了室内试验分析，主要研究内容和结论如下： 1、分析了珊瑚礁的区域工程地质环境、海洋水动力条件、地形地貌特征、岩土体条件等因素对岛礁工程建设的影响，对珊瑚礁的礁体类型进行了划分，结论认为可干出的环礁和台礁比较适合各类工程建设，其中环礁的礁坪是理想的工程建设场所。

" One of his most-quoted saying is his own criticism of his discoveries:"I don't know what the world may think of my labours, but to myself it seems that I have been but as a child playing on the sea-shore; sometimes finding some prettier pebble or more beautiful shell than my companions, while the unbounded ocean of truth lay undiscovered before me.

" 被人引用最多的一句话是牛顿对自己发明的评价："其实我不知道大家对我的成果怎么看，但对我来说，我只不过像是一个在海滩玩耍的孩子；只是比我的同伴多看见些漂亮的鹅卵石，或是美丽的贝壳，可大海般浩瀚无垠的真理还在等着我们去探索。

Abstract］ objective to assess a new imaging technique,optical coherence tomography,for the diagnosis of central serous choroidoretinopathy.methods forty-five cases (45 eyes) of csc were examined by ophthalmoscopy,binocular indirect ophthalmoscopy and oct.some patients were monitored by oct.results in images of oct in 45 eyes of csc,42 eyes showed serous neurosensory detachement,2 eyes appeared retinal pigment epithelial detachement and 1 eyes combined neurosensory detachement with pigment epithelial detachement.monitoring images of oct in 9 eyes revealed absorption of serous fluid and decrease of neurosensory detachment.conclusion oct is potentially useful as a new and noninvasive diagnostic technique for quantitative examination of patients with csc and objectively monitoring the clinical course of the serous retinal detachement in this disease.

摘要］ 目的评价光学相干断层成像(optical coherence tomography，oct )对中心性浆液性脉络膜视网膜病变的临床诊断价值。方法对45例(45眼)中心性浆液性脉络膜视网膜病变患者散瞳后分别进行直接检眼镜、双目间接检眼镜、oct 检查。9例复查时再次进行oct检查。结果 45眼中心性浆液性脉络膜视网膜病变的oct 图像，42眼表现为单纯神经上皮层脱离，2眼为单纯色素上皮层脱离，1眼同时存在神经上皮层脱离和色素上皮层脱离。9眼复查的oct通过测量脱离高度的降低可观察到液体的不同程度吸收。结论 oct 是一种新的、无损伤性的、非接触性的、并能定量的检查方法，能明确中心性浆液性脉络膜视网膜病变的脱离部位，并能进行定量的追踪观察。

During setting up an estimate system of determining the constants and choosing the demand model, the exactitude of the Saic Cherry automobile Co. Ltd short-range demand forecast would be improved, the automobile selling would have an reference forecast model.

本文希望通过对模型系数的评价体系的建立及需求模型的选取，对奇瑞公司的短期需求预测的精确度有所改进，为汽车销售业提供一个可供参考的预测模型。

We should correctly grasp the connotative meaning of ILC, take"Chinese"as the root, pursue "integration"and pay attention to the"process". We should also develop a new teacher-student view, complying with the requirements of the times.The traditional take-in learning and ILC should be combined with each other. The diversification of ILC's implement and the exploration and design of its theme can both promise a more dynamic and energetic future of ILC.

应正确把握小学语文综合性学习的内涵，扎根"语文"，追求"综合"，关注"过程"，顺应时代要求，发展新型师生观；传统的接受性学习和语文综合性学习应相互结合；小学语文综合性学习的实施类型应多样化；小学语文综合性学习主题的发掘与设计和建立合理的小学综合性学习的评价体系都可使语文综合性学习更加生机勃勃。

The AVS-SEM distribution in the sediments of Guanting Reservoir and Yongding River was studied and the metal concentration in the water above the sediments and the pore water was measured. Based on the results, the reaction between the sediments and metal ions were discussed and the heavy metal pollution of the sediments in Guanting Reservoir and Yongding River was evaluated preliminarily.

官厅水库沉积物，由于处于缺氧性环境，沉积物中的酸可挥发性硫化物控制着大多数金属离子在沉积物和孔隙水两相间的分配，本文通过现场采样，分析了官厅水库和永定河沉积物中的AVS—SEM的分布，同时测定了沉积物上覆水以及部分样点的孔隙水中的重金属浓度，探讨了沉积物与重金属离子的作用；并根据采样分析结果对官厅水库及永定河沉积物中的重金属污染做了初步评价。

The long-term food security means a reasonable deployment and the sustainable usage of agriculture resource, as well as stable and unstinted food supply capability. Further more, it concerns about the middle and long term forecast of China\s food supply and demand, agriculture competence and farmer\s income within WTO frame, and the protection on agriculture environment.

短期粮食安全指保证粮食的短期供需平衡和粮食价格的稳定，主要考虑短期粮食安全的指标评价、粮食储备和短期粮食国际贸易等问题；长期粮食安全指农业资源的合理配置和可持续利用，保证国家有稳定的、充裕的粮食供给能力，主要考虑我国粮食供需的中长期预测、WTO 框架下农业的竞争力与农民收入以及农业生态环境保护问题。

Genetic cluster analysis is similar based on the results of morphological and DNA markers, the five populations could be divided into three groups. But there are different groups sort of individual locations, reflecting the similarities and difference about the analysis of the relationship between population with the two kinds of markers, It could be concluded that there was coupling and relevance to some extent in evaluating genetic diversity with the same experiment sampling by morphological and SSR marker variation. However, there was also differences. In research, the two can complement each other.8. Identification of Genetic Relationship of Amygdalus plants by SSRThe genetic relationship among 55 Amygdalus plants collections, belonging to 6 species and collected from both homeland and abroad were identified via SSR molecular marker technique.

新疆野扁桃遗传多样性不同研究分析方法结果的比较与评价表型与DNA二种水平的遗传标记方法揭示的遗传多样性水平有差异，表型性状比DNA分子标记具有更大的变异性；其受到环境的影响较大，也即对环境更敏感。2种水平的遗传标记聚类结果将野扁桃5个不同分布群体均可分为3个大类群，但是出现有个别不同的群体排序位置，反映了2种标记在分析种群间关系上的异同性，从本研究结果来看，说明表型与DNA标记有一定的耦合性和相关性，但也存在差异，在研究上可以互为补充。8。

The result showed that Imperata cylindrical, Digitaria sanguinalis, Erigeron acer Xanthium sibiricum and Hedyotis auricularia are the species with high tolerance to heavy metal pollutions adapted to the adverse conditions of wastelands. These species can be used as pioneer plants for recovety of the vegetation in the manganese-mined wastelands. The individual event pollution index of the heavy mentals, compared to their background values are higher than 2, with Pb as an exception, indicating that the soil in these areas has been contaminated and that Mn and Cd are the elements creating most serious pollution problems.

结果表明，白茅、马唐、飞蓬、苍耳、耳草对重金属有较强的耐性，而且能适应废弃地的不良环境，可作为锰矿废弃地生态恢复的先锋植物；用3种不同的背景值对废弃地土壤重金属污染程度的评价结果是一致的，除Pb外，5种重金属元素单项污染指数均大于2，表示被污染，其中以Mn、Zn、Cd污染最为严重。

STUDY OF DEVELOPING MECHANISM AND REGULATION OF CHINESE RESOURCE-BASED CITY Resource-based city of China is a traditional research realm of Geography, however the emphasis of research shifted with the times. Before 1980s,the research based on the resource explorement, emphasizing on the evaluation of resource conditions and industry distribution; after that it turned to the research of the developing diversity, whose emphasis became the adjustment of industry structure and the sustainable development.

资源型城市是地理学研究的一个传统领域，但不同时期研究的重点有所不同。80年代之前主要着眼于资源开发和基地建设，研究的重点主要是资源条件评价和产业布局；而80年代之后主要着眼于区域和城市的发展差异，研究的重点倾向于产业结构的调整和可持续发展。
