According to the model, the deflection and main pre-brace parameters are illustrated with the Jinsong station of the tenth line in Beijing. It demonstrates that the curve shape of theoretical result, computing result and the on-set measure result are uniform in the main and the change law is similar; that the circumferential space of pipe-roof has a optimum value while satisfying the pre-brace function; that the relation between diameter of steel pipe and flexibility of barrel vault meets negative exponential function. And the diameter of steel pipe has a optimum value.

依据该模型，以北京地铁10号线劲松车站管棚支护为例，着重对管棚的挠度和主要支护参数进行的分析表明：理论结果与计算结果和现场量测结果的曲线形状基本相同，变化规律相似；在满足预支护作用的同时，存在相对较优的管棚环向间距；钢管直径与管棚挠度之间符合负指数函数关系，管径存在最佳值。

Pointing to the feature that the strata developed controlled by palergeomorphy,reef bank grew upward and sea level relative variability,then on the basis of synthetically analyzing Hthology and logging curves features,and applying the theories of sequence stratigraphy,divided Lianglitage Formation into TST and HST from bottom to top,and 3-4 parasequence sets,8 parasequences,and 11 members.furthermore, recognized shelf margin reef,grain bank, shelf margin bioherm and interbank sea these four facies and 12 subfacies.

针对上奥陶统良里塔格组地层的发育主要受古地理、礁滩体向上营建和海平面相对变化控制的特点，在进行岩性特征、测井曲线特征综合分析的基础上，应用层序地层学原理和方法，将良里塔格组自下而上划分为海侵体系域和高位体系域两个体系域，3～4个准层序组、8个准层序，细分为11个小层。并发育棚缘生物礁、粒屑滩、棚缘生物丘、滩间海4种相，12种微相亚相。

Beijing's guest international racing pigeon loft is Beijing's guest coffee co. investment sets pigeon breeding, training, King-cheung, sales of large international carrier pigeon loft.

北京赛客国际赛鸽公棚是由北京赛客咖啡有限公司投资兴建的集信鸽养殖、训放、竞翔、销售于一体的大型国际化信鸽公棚。

The Biaoyou international Racing pigeon center accounts for 35 Chinese acres, the pigeon shed area more than 1500 square meters, includes the observation awning, the treatment awning, the laboratory, the consulting room and so on.

Now the studies about broad-leaved evergreen plants mainly focus on some singular elements experimentized in laboratories. The paper studies the effect of cultivation methods such as plastic canopy, shade canopy, coving ground with pine bark on cultivation environment in two year.

目前对常绿阔叶植物的研究主要集中在单因子和实验室内的研究，而本文通过2年的观察和实验，研究塑料棚、荫棚、地面覆盖等保护地栽培措施对栽培环境的影响，而环境的变化进一步影响常绿阔叶植物在冬季的越冬表现。

In this study, cultivation methods and treatments such as plastic canopy, shade canopy, coving ground, anti-transpirant-pretreated, pachobutrazol-pretreated, burying for overwintering is used on the several broad-leaved evergreen plants in Beijing including glossy privet, Japanese privet, Japanese holly "Convexa", evergreen euonymus "Cu zhi", wintercreeper euonymus, English ivy, leatherleaf viburnum, littleleaf box "Wintergreen", and star Jasmine.

在研究中，采用塑料棚、荫棚、地面覆盖、喷施抗蒸腾剂、多效唑、埋土越冬等措施和处理对北京地区几种常绿阔叶植物——女贞、日本女贞Ligustrum japonicum、皱叶荚蓬、龟甲冬青(Ilex crenata'Convexa)、'粗枝'大叶黄杨(Euonymus japonicus 'Cu zhi')，'冬绿'小叶黄杨(Buxus microphylla'Winter-green')，络石、洋常春藤、扶芳藤进行了实验。

In this paper, the important thing is analysis the function of the pipe umbrella in excavating period.

隧道开挖过程中管棚的作用机理分析是本文的重点，在分析了国内外的研究成果的基础上，提出了管棚的受力模式，并推导出管棚受力条件下的挠度方程。

"The northern ice front of the Wilkins Ice Shelf has become unstable and the first icebergs have been released," Angelika Humbert, glaciologist at the University of Muenster in Germany, said of European Space Agency satellite images of the shelf.

德国明斯特大学冰川学家安洁莉卡杭柏特，在谈到欧洲航太局的冰棚卫星影像时评论道：「威尔金斯冰棚北端已呈现不稳定的状态，因此在冰棚断裂后释出了第一批冰山。

The new icebergs added to 330 sq kms of ice that broke up earlier this month with the shattering of an ice bridge apparently pinning the Wilkins in place between Charcot island and the Antarctic Peninsula.

本月稍早已有330平方公里的冰脱离了冰棚，近日这起崩裂又增加了破冰的面积。冰桥塌陷是造成冰棚再次破裂的原因。这座冰桥无疑能将威尔金斯冰棚固定在沙科岛和南极半岛之间。

I thought, there would be a lot of trouble if someone fell down into the water. On the oyster shed I saw a lot of oyster shells,and just when I was curious about why oyster shed floated, the guide said it was relying on the buoyancy of Styrofoam to support the weight of the oyster shed, although I do not know the number of Styrofoam blocks under the shed, but I know that there must have been a lot of Styrofoam blocks.

在蚵棚上，我看到了许多蚵的壳，正当我好奇蚵棚为什麼会浮起来时，导览人员说他是靠保丽龙的浮力来支撑蚵棚的重量，虽然我不知道下面到底有多少个保丽龙块，但我知道下面一定有很多保丽龙块。
