拱腹

As far as orthogonal vierendeel latticed shell was concerned, its characteristic under static loads and dynamic loads was analyzed systematically in this thesis.

取出一榀空腹拱为研究对象，分析了它与实腹拱在受力特点和性能的异同。

A minimum of 4 timber props and 2 horizontal joists are required for the slab soffit.

混凝土拱腹最少要有四个木头支撑和两个水平连接。

T shaped props must be provided for beam soffit.

梁拱腹必须有T形支撑。

Based on f the stability computation theory of structures are elaborated in brevity and in consideration of material elasticity and geometrical nonlinearity, the 3-D model of finite element in studying on in-plane elastic ultimate load-carrying capacity of 工-section arches with holes in soffit is built by ANSYS software.

本文在简要阐述结构稳定计算理论的基础上，利用ANSYS计算软件，在弹性材料、几何大变形条件下建立了研究腹板开洞工形截面钢拱平面内弹性极限承载力的有限元三维模型，并把极限承载力的各种影响因子设为变量，形成了整个计算过程的MAC文件。

The interface bond capability and the failure mode of soffit strengthening are studied, as well as the influence of strengthening concrete technique to the interface bond capability. The cracked load, the failure load, the tension stiffness, the stress of the steel bar and the cracks of the strengthening arch are compared with those of the contrast arch.

第五，考虑到实际工程应用，设计并制作了采用增大截面法在拱腹部位加固钢筋混凝土拱圈试件，研究拱腹加固新老混凝土结合面的粘结性能及破坏形式和补强混凝土的施工工艺对新老混凝土结合面粘结性能的影响。

The thrust at spring of spandrel arch makes it different between compound arch bridge and ordinary arch bridge.

复拱桥腹拱拱脚对主拱有较大水平推力作用，这一水平推力使得复拱桥受力与普通拱桥有所不同。

The finite element analysis shows that the two kinds of trial designs meet demand.(3) Compared the static behavior of three kinds of designs with each other, the results show that using the steel web concrete combined box tie beam can reduce the structure internal force and is beneficial to structure stability.

采用波形钢腹板组合系梁和平钢腹板组合系梁进行了钢管混凝土拱梁组合桥的试设计，并进行对其有限元分析，结果表明两种试设计方案均满足受力性能要求。

Major characteristics:The breed has moderate body conformation,with mediumsized head,ununiform shape and depth transverse wrinkle,fairly small and lop ears,short and stout neck,wide and concaved back,arched ribs,large and drooping be11y,short and rough legs,unclamp rump,sleeping pastern,monkey-liked hooves.

主要特性：体型中等，颈粗短，有垂肉，背腰宽，背线多凹陷，肋骨拱曲，腹大下垂，四肢粗短，大腿欠丰满，多卧系，撒蹄，群众称"猴子脚板"，头中等大小，额部有形状和深浅不一的横行皱纹，耳较小、下垂，被毛为黑白花。

Used on exterior and interior walls, roofs and soffits and on

来实PA小肋板适用于外墙和内墙、屋面和拱腹，以及带有

The soffits below the bridges and under the cantilevers pick up the bright colors of the harbor; contain orange on the undersides of the Langenlinie, bright yellow on the undersides of the Marmormolen.

天桥和悬臂下的拱腹为整个海港增添了一丝明亮的色彩；&L&楼和&M&楼的下腹分别呈现出橙、黄两种颜色。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
