By starting with the basic theory of metropolis ring spatial development and drawing the experience of domestic and foreign metropolis ring, the paper makes a discussion on efficiency of metropolis ring pattern, development phases and spatial structure. It points out the three main phases of metropolis ring development—rudiment, growth and autumn. From the spatial structure, the paper stresses that metropolis ring has the features of "ring and layer", the size of the "ring and layer" has the direct ratio with city size, convenient degree of external transportation and city radiant intensity. It owns the idea that adjustment and control of metropolis ring spatial development should reflect the following concepts, including globalization, regional integrated harmony, views of scientific development, harmonious society, consultative city planning, people-oriented principle, guided city planning and responded city planning.

从都市圈空间发展的基础理论入手，借鉴国内外都市圈发展的经验，本文对都市圈模式效应、发展阶段和空间结构进行了探讨，认为都市圈发展阶段主要分雏形期、成长期和成熟期三个阶段；从空间结构看，都市圈具有"圈层式"的特征，圈层的大小与城市规模、城市对外交通的便利程度、城市对外辐射强度成正比；都市圈空间发展调控应体现全球一体化理念、区域整体协调理念、科学发展观理念、构建和谐社会理念、协商规划理念、以人为本理念、导向型规划理念和规划应变性理念。

Yangtze Delta Urban Economic Circle, Zhujiang Delta Urban Economic Circle, Beijing-Tianjin-Hebei Urban Economic Circle, Chengdu-Chongqing Urban Economic Circle, and Wuhan Urban Economic Circle are five important urban economic circles, among which, four economic circles except Wuhan Urban Economic Circle have club convergence phenomenon and this club convergence is greatly related to industrialization degree, inner economic structure and innovative ability of the five economic circles.

长江三角洲城市圈、珠江三角洲城市圈、京津冀城市圈、成渝城市圈、武汉城市圈是我国五个重要的城市圈；其中，除武汉城市圈外其他四个城市圈均存在不同程度的俱乐部趋同，而且这种趋同和五大城市圈的工业化程度、内部经济结构及创新能力有很大关系。

This study shows that there are 4 kinds of volcanic facies in deep volcanics in north Songliao Basin: eruptive facies, overflow facies, volcanic vent facies and volcanic sedimentary facies. There are 4 volcanic eruption cycles: Huoshiling period, Shahezi period, Yingchengzi period and Quantou period. There are 4 structural evolution stages: north-south accumulation, west-east subduction, uplift mantle and thin crust, alternative open and close. There are 4 kinds of pool-forming patterns:(1) pattern with the migration along the unconformity and fault to the near crater;(2) pattern with the migration along unconformity and fault to the rift margin;(3) pattern with the migration along unconformity, fault and fracture to the source rock;(4) pattern with the migration of the deep gas along the deep and large fault to the volcanic trap.

研究认为，松辽盆地北部深层火山岩主要存在四种火山岩相：即爆发相、溢流相、火山通道相、火山沉积相，划分为四个火山喷发旋回：即火石岭期、沙河子期、营城子期、泉头期，经历了四个构造演化过程：即南北夹攻、东西俯冲、幔隆壳薄、开合交替，具有四种成藏模式：即沿不整合面和断层运移至近火山口处火山岩圈闭聚集成藏模式、沿不整合面和断层砂岩疏导层运移至断陷边部火山岩圈闭聚集成藏模式、沿不整合面及断层、裂缝运移至源岩区内凹中隆火山岩圈闭聚集成藏模式、深部无机成因天然气沿深大断裂运移至火山岩圈闭聚集成藏模式。

By the types of oil or gas reservoirs, three kinds of oil or gas accumulation models fit to Wuerxun depression. They are the model of oil or gas migrating and accumulating in sandstone lens or fracture traps of source rock, the model of oil or gas accumulating in fault-block or fault-screened traps through vertical migration, the model of oil or gas accumulating in structural-lithological traps migrating laterally in short instance through sandrock.

在此基础上，根据油气藏类型总结出乌尔逊凹陷南二段油气成藏模式有①源内砂岩透镜体或裂缝圈闭油气运聚成藏模式②油气沿断裂垂向运移于断块或断层遮挡圈闭成藏模式③油气沿砂体短距离侧向运移于构造—岩性圈闭油气藏模式。

According to these mentioned above, it can be concluded that there are 4 types of accumulation model in west slope region, that is, sandstone up-dip trap, structure and structure—lithology trap, fault—lithology trap, sandstone lenticular body trap, and that oil-gas accumulation and distribution are mainly controlled by some factors that is trap growth, relationship of between trap and space orientation of oil-gas migration pathway, connection area of centripetal flow and centrifugal flow, oil-gas preservation condition and unconformability.

在上述基础上，总结出西斜坡区运聚成藏模式主要有砂岩上倾尖灭圈闭油气运聚成藏模式、构造及构造-岩性圈闭油气运聚成藏模式、断层-岩性圈闭油气运聚成藏模式、砂岩透镜体圈闭油气运聚成藏模式4 种模式。在上述基础上，总结出油气成藏与分布主要受圈闭发育、圈闭与油气运移路径空间位置关系、向心流与离心流交汇区、油气保存条件和不整合因素的控制。

During hollow spindle spinning, the yarn package rotates at a high speed, yarn untwists from the package and forms a balloon. The yarn balloon phenomenon exists commonly in spinning processes. The shape of yarn balloon is a general displacement of the forces acts on the balloon yarn. There is a close relationship between the yarn balloon shape and the forces acts on the balloon. The balloon shape is decided by the spinning force, on the contrary, we can find the value of the spinning force according to the yarn balloon shape. To a great extent, the spinning tension impacts the yarn structure and quality.

空心锭子纺纱过程中，纱线卷装随锭子高速转动并退绕，因而产生了气圈现象，气圈是纺纱过程中比较普遍的现象，气圈的形态是纺纱过程中气圈纱线受力的综合体现，纱线张力与气圈形态密切相关，纱线张力决定了气圈形态，反之则可根据气圈形态算出纱线张力，纺纱张力在很大程度上会影响成纱的结构和质量，而纺纱张力不便直接测量，因此通过观察气圈形态来估计纺纱张力是十分可行的。

Based on the detailed study of seismic tomography image in South China, and according to the geotectonic environment and shape and heat of asthenosphere upwelling, we divided the structure of lithosphereasthenosphere at the Mesozoic upper mantle of Eastern China into three types.(1)Continental platform area (North China platform and Yangtze platform): asthenosphere upwelled along paleorift; over the plume head, the granitic rocks of crust and mantle mixed and correspondingly, Au, Cu, Mo, PbZn, etc. mineralizationconcentrated regions were formed; and at the steep contact belt of asthenosphere and the thick area of lithosphere, mediatebasic complex was formed.(2)Central area of fold zone: asthenosphere was "recumbent" at suitable depth, with adequate heat and in a great extent; by heat conduction, the interior of partial crust remelted, and the crustsource granitic rocks, and correspondingly, W, Sn and rare elements mineralizationconcentrated regions were formed.

在深入研究华南地震层析成像的基础上，按照大地构造环境和软流圈上涌形状和热度，将中国东部中生代上地幔中岩石圈软流圈构造划分为3类：(1)陆台区，软流圈沿古裂陷上涌，其柱头上方形成幔壳混熔花岗质岩及相应Au、Cu、Mo、PbZn等矿集区，并于软流圈与岩石圈厚区之陡接触带形成中基性杂岩及相应Fe矿集区；(2)褶皱带中心区，软流圈在适当深度、热量充足、较大范围内&平卧&，因热传导而致使地壳内物质部分重熔，形成壳源型花岗质岩及相应的W、Sn、稀有元素矿集区；(3)褶皱带边缘区(大兴安岭南部及华南南缘)，在软流圈上涌柱上方形成幔源或幔壳混熔的花岗质岩，相应为Cu、Au、PbZn、Mo、Ag矿集区。

"Dog Flea" is a ring game song in which kids hold hands and circle around one person in the middle. That person tries to break out of the circle on the line "dog flea is a bitin' me," and the group responds,"don't keer caint git outa here." When someone finally does break out of the circle, everyone chases him or her until that person is caught.

狗身上的跳蚤」是一首围圈歌唱游戏，游戏进行时，孩子们围成一圈站立，手牵手把一人围在圈中；当唱到「我被跳蚤咬了一下」( dog flea is a bitin' me )时，站在圈中的必须试着破圈而出，而在同时，围成圆圈的孩子们则回以「你不能从我这儿出去」( don't keer caint git outa here )；最后，当有人破圈而出时，所有的人会开始追逐那个人，直到那个人被抓住为止。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
