箱形的

The manufacture process is very; the parts and components, including electric motor, reducer, breaker and cable reels, all adopt the updated products; the whole machine has advanced technologies, reliable performance and novel structure; it has many safety protection facilities, such as: overload equipment, height indication equipment, stroke ultimate position terminal protector, electric rail clamp and anemoscope to ensure the normal operation of the equipment.

跨度大，一机多用，可同时装置主钩、副钩等结构；主梁、横梁、支腿等主要结构为箱形梁，强度与刚度好，制造工艺简单；零部件包括电机、减速器、制动器、电缆卷筒等均选用最新产品，整机技术先进，性能可靠，结构新颖；有超载装置、高度指示装置、行程极限位置终端保护装置、电动夹轨器、风速仪等安全设施，保证设备的正常运行。

In the1940' s Brandt found an old Kodak box camera with a wide-angle lens focused on infinity and began using it to photograph nudes.

在本世纪四十年代，他找到了一架有广角镜、以无限聚焦的旧式柯达箱形照相机，于是就开始用它来拍摄裸体。

According to thermo-elastic-plastic theory, the simulation of welding good-sized steel box-beam is carried out.

本文根据热弹塑性理论，对大型厚板箱形梁对接焊的焊接过程进行了仿真。

The duct type jib of No.1 deck crane was found heavily bent and broken at the position of about 6.5m away from its heel about 0.8m in length.

一号甲板吊的箱形吊臂发现在离根部 6.5 米处严重弯曲并裂开约 0.8 米。

With the development of the prestressed concrete construction technology, more and more prestressed concrete box girder bridges have arisen in our nation. However, after construction, the appearance of the cracks on some of these bridges takes some unfavourable influence on the structures. In common sense, we should take some methods to strengthen and repair these bridges as soon as possible, but because of the civil pecuniary condition, we cant repair all the broken bridges in one time. Therefore a scientific estimation must be made about the load-carrying capacity of these prestressed concrete box girder bridges with cracks, so that we can decide which bridge should be repaired firstly.

随着预应力施工技术的不断进步，我国已拥有越来越多预应力混凝土箱形梁桥，这些桥在使用一段时间后，有很大一部分箱梁出现了大量的裂缝，这些裂缝的出现对桥梁结构将产生不利的影响，所以应尽可能的对其进行加固修补，但限于国内实际经济状况，我们不可能一次性全部进行加固改造，需要对在役的这些开裂后的预应力梁桥的工作状态特别是承载力做出科学的评判，以便区分轻重缓急，优先实施。

The numerical results were obtained for Reynolds numbers of 100, 1000 and 10000 as working examples.

数值结果给出了一箱形流道内雷诺数分别为 100，1000 和 10000 时的流场。

Another example, the consolidation phase of market entry, usually box or triangular form of convergence, and the medium-term average price (normally 10-20 antenna) deviates from the rate is gradually shrinking.

再如，市场进入盘整阶段后，通常出现箱形或收敛三角形态，价格与中期均线(一般为10-20 天线)的乖离率逐渐缩小。

The curve continual steel box Liang shearing force stagnates the effect finite element analysis box section Liang has the big flexural rigidity and torsional stiffness, the stress performance good, spanning ability big, on the bridge the field of vision open and so on the merits, is in the bridge design the commonly used structural style, when receives under the dead load or the symmetrical live load function winding, because the lifting surface detrusion causes its bending stress to present the non-uniform distribution condition along the Liang width direction, this phenomenon is called "the shearing force to stagnate the effect".

曲线连续钢箱梁剪力滞效应的有限元分析箱形截面梁具有较大的抗弯刚度和抗扭刚度、受力性能好、跨越能力大、桥上视野开阔等优点，是桥梁设计中常用的结构形式，在受恒载或对称活荷载作用下挠曲时，由于翼板的剪切变形致使其弯曲应力沿梁宽度方向呈现不均匀分布状态，此现象称为&剪力滞效应&。

Besides these,deck beam finite element analysis method can be applied flexibly to box girders with different cross-section or rib-plank structure and those without orthogonal support .

板段元法适用于其他断面形状的箱梁结构或肋板式结构，也可用于斜交箱形直梁的分析，具有较好的适用性。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.
