BORDER PORT MANZHOULh URBAN FUNCTION AND SPACE DEVELOPMENT

Manzhouli is the largest land port city on the Sino-Russia border, transit cargo through the land port amount-ed to 5.95 million tons, transit tourists were 304 500 in 2000. It stands at the joint place of China, Mongolia and Russi-a, faces to Siberia area of Russia, receives direct support from the Northeast China and Bohai Sea Rim Area, and possess-es priorities in geographical location, land port infrastructure, water resources, coal resources, tourist resources andgreat potentiality in economic cooperation with Russia. The future urban function is a key port on the First Eurasia Continen-tal Bridge. Manzhouli Port will keep its first place between China and Russia land transport, and it is forecasted that thetransit amount through Manzhouli Port will go up to 10 million tons in 2005 and 20 million tons in 2010. It will be construct-ed to be a trade center of the peripheral area extending to Russia and Mongolia, a key export-oriented processing industri-al zone supported by industries such as export processing industries, export agriculture, trade services, technology trad-ing and the other service industries. It keeps being a well-known touring city for trade, shopping, sightseeing, vocation,local food, recreation and cultural events. To build Manzhouli Export Processing Industry Zone will improve city econom-ic structure, and the main sectors are organic food processing, livestock products processing, garment and furniture indus-try. Moreover, Manzhouli Export Processing Industry Zone will eventually be upgraded to be a border free trade zone.The city functional transition will inevitably affect urban spatial restructure and its expansion. The city space transforma-tion will develop as such: one development axis of No. 301 highway paralleling with Bin - Zhou(Harbin - Manzhouli) rail-way which cuts through central part of Manzhouli City, and links Zhalainuocr District with central city; three urban unitsincluding central city, Zhalainuocr District and Manzhouli Interchange Trade Zone; cohesion with Aoerjin and Cuogangpastures; regional dual-nuclei structure of Hailaer City and Manhzouli City; and the Manzhouli-Zabaykalsk Free TradeZone.     

平衡剖面的制作流程及其地质意义

平衡剖面技术是地质思维和计算机技术的结晶,使对断层构造的研究提高到定量阶段,其依据是在垂直构造走向的剖面上,地层长度和面积(2D)或体积(3D)是均衡的。在此原理基础上利用数学手段对盆地的构造发育史进行正演和反演模拟,直观地再现地下构造的原始几何形态,迅速提供地震剖面的构造解释方案,并对解释结果进行检验(不平衡的剖面其解释一般有问题),为深刻认识构造发育史、分析油气运移及聚集规律提供依据,提高了工作效率。其结果也为盆地模拟、油藏模拟、定量计算构造伸缩量等地质研究打下了坚实的基础[1]。     

矿产资源开采中的供地方式

矿山企业是用地大户，往往也是占用耕地、污染环境、破坏生态的大户 　对矿山企业用地实行有偿使用，并由其对占用的耕地进行复垦，对污染的环境进行治理，是用 地制度的一项改革。但这一改革还不尽完善，使矿山企业面临诸多新的矛盾 　如何完善矿产资源开采中的土地供应方式，作者的一些设想颇有见地     

Influence of the Choice of Core-Envelope Transition Point on the Binary Merger of Two Main-sequence Components

We have studied the influence of different choices of core-envelope transition point on the final merger of contact binaries with two main-sequence components. A binary of 1.00 + 0.90M⊙ with an initial orbital period of 0.35d is examined. The mass fraction of the primary mixed with the matter of the secondary, qmix, determined by the chosen core-envelope transition point, ranges from 0.04 to 1.00 in our analysis. If as qmix< 0.8, none of the     

奎屯河山前扇形地的地质灾害分析

奎屯河山前扇形地(简称奎屯扇形地)特有的自然地理条件,存在地震、洪水、泥石流、滑坡、崩塌和尘暴等多种地质灾害,并具有特殊的发生规律和表现形式,本文通过调查研究对地段性的地质灾害活动进行了分析、评价,初步提出有方向性的躲避和有目标性的抗灾.以及主动控制的治理措施.     

浙西北江山─绍兴断裂带构造演化特征

江山—绍兴断裂带是中国南方最重要的构造带之一。它是江南陆块与华夏陆块神功运动形成的碰撞拼贴带。它表现出明显的多期变形、构造叠加的特征：神功运动形成近东西向平卧褶皱；印支运动沿断裂带有向北西强烈的推覆挤压。断裂带不同时期的活动反映了不同特征的构造环境，形成不同的构造变形特征，并对两侧的地质历史具有明显的控制作用。     

恒星内部电荷屏幕对电子俘获反应的影响

本文分析了在恒星环境下，电荷强屏蔽对原子核电子俘获反应的影响，分析中忽略了电荷屏幕对核跃迁矩阵元的影响。作为例子，分别讨论了电荷屏蔽对核素＾３３Ｓ、＾３０Ｐ和＾５７Ｆｅ的电子俘获率的影响。结果表明：在较低温度和较高密度下，由于电荷屏蔽，其电子俘获率相对于无屏蔽情形有明显降低，这可能对恒星晚期演化和超新星爆发理论带来明显的影响。     

恒星的初始-终止质量关系

本文研究了星族ＩＲＧＢ／ＡＧＢ星外壳结合能为零时的核质量与其初始质量的关系，发现此关系与Ｗｅｉｄｅｍａｎｎ和Ｋｏｅｓｔｅｒ观测得到的初始终止质量关系相符，并与Ｚｈａｎｇ和Ｋｗｏｋ得到的行星状星云核质量分布的观测结果相符合．采用相同的假设，本文还得到了星族ＩＩ恒星的初始终止质量关系．对于相同的初始质量，星族Ｉ恒星的终止质量比星族Ｉ的大～１０％－２０％．
