| 4. | Chapter two is a report on genetic organization of the hindlll - l fragment of hasnpv . the fragment that is 7501 bp long and located at map units ( mu ) 12 . 3 - 17 . 9 of the viral genome was sequenced 对棉铃虫单核衣壳核多角体病毒( hasnpv )的研究历史和近期对hasnpv的基因组学研究以及本论文的研究内容作了简要介绍。 |
| 5. | In the present work , sequence - paleogeographic mapping is implemented on the s econd member of the upper triassic xujiahe fm . and the upper jurassic ponlaizhen g fm . in western sichuan , china , with system tracks taken as the mapping units 研究重点选择上三叠统须家河组二段和上侏罗统蓬莱镇组,按体系域进行层序-岩相古地理编图。 |
| 6. | On the basis of mapping unit of 50m 50m the paper makes use of logistic regression analysis and information value method respectively to have a hazard assessment of landslide on main urban areas of wanzhou and gets a hazard map finally 文中使用50m 50m的评价单元,分别使用逻辑回归分析法和信息量法,对万州主城区研究区进行了滑坡危险性评价,最终得到的危险性图与已有的滑坡分布吻合良好。 |
| 7. | Abstract : on the basis of a study of sequence stratigraphy , with the systems tract and related boundaries as the mapping unit and using the systems tract condensation method and instantaneous map production method , the authors have compiled the permian sequence paleogeographic map of southwestern china and systematically elucide the characteristics of the permian sequence paleogeographic evolution of the region 文摘:在层序地层研究成果基础上,以沉积体系域和相关界面为编图单元,采用体系域压缩法和瞬时编图法,编制了西南地区二叠纪层序古地理图,全面系统地阐述了该区二叠纪层序古地理演化特征。 |
| 8. | Abstract : sequence - paleogeographic mapping is to use information gained from integrated pa leogeographic and sequence stratigraphic studies to produce a synchronic or inst antaneous lithofacies - paleogeographic diagram , in which the recognized key bound ary - surfaces , sequences and system tracks are taken as mapping units 文摘:层序-岩相古地理编图就是将岩相古地理的研究和编图与层序地层学的研究紧密结合,利用层序界面和其它关键界面,以体系域、层序或等时界面为编图单元编制等时或瞬时岩相古地理图。 |
| 9. | In this paper , i establish a set of updating the basic land - use map technology and flow after i go deep into studying the methods of updating the basic land - use map based on 3s technology . it is very important point that i bring forward some methods of change information automatic detected founding on land - use map unit , cross correlation analysis with multispectral image and object - oriented classification aiming at difference data and difficult identifying change information problems . and then , i compile the programme and practise validating to examine technics flow 本文在深入研究了基于3s技术更新土地利用图件的方法基础上,从实用化的角度出发,建立了一套利用3s技术更新土地利用基础图件的技术流程与方法,并针对不同的数据情况和变化信息自动提取等问题提出了基于土地利用图斑单元的知识库变化信息自动发现方法、多波段遥感影像交叉相关分析变化识别方法及面向对象的遥感影像分类变化检测方法。 |
