查询词典 beams

It is found that the stiffness of the beam is inadequate, which result in two gaps between the central beams of the moving beam; there are two weak strength sections where existing in the tie rod cylindrical hole and chamfering nearby the perforation cylinder.

A new anchorage system for girder to obtain pretension stress at section top-edge in middle of span is shown. Based on the research of bi-prestressing beams inside test-room and the test of the prestress bar character, method for calculating the full size gird and choosing section are proposed. A new-style corrugated pipe which is shown in the paper is used, to solve the transformation of compressed thread bar and the contradiction between loss of friction resistance and pumping in pipe.

I'll describe a shot from the Exterior Brookfield sequence of an exterior of a row apartment on fire with an explosion blasting out the third story windows. The shot was composited on an Inferno by Bob Wiatr. We started with a live plate of the street scene. Our first task was to remove a foreground chainlink fence and camera crew. We recreated the fg matching the flashing ambulance lights. To create a snowy, misty look we used a number of logic ops of the bg with a mist plate which was basically the bg heavily blurred and multiplied back onto itself, graduating to create a sense of dimensionality. Glows were added around lights and flames using Sapphire plug-ins and light beams were added to streetlights. Four or five layers of 3d particle snow created in Maya were combined with practical elements varying in size and focus depending on distance from the camera.A miniature explosion element was incorporated into the comp, also with added glows, interactivity with the building, and rotoscoping of foreground objects. The entire comp was then time warped for editorial matching with the subsequent cut.

我可以描述一个Exterior Bookfield的几个镜头，那是一排的公寓着火，在三楼窗户引起爆炸，这个镜头是Bob Wiatr用Inferno合成的，我们用一个现场的街道镜头开始，我们的第一个任务是删除一个在前景中的链条状的篱笆和摄像人员，我们重新制作了前景以期与前景中的闪烁的救护车灯匹配，为了制作一个下雪的雾蒙蒙的效果，我们用了大量的logic ops，用了一个雾层，这个层基本上就是把背景尽量模糊然后再把它重新加到背景上面，渐变式的制作出一个层次感，自发光用Sapphire插件加在灯光和火焰的周围，而光线被加到路灯上，在maya中制作的四到五层的三维的粒子雪用来和不同大小的真实的素材混合在一起，焦距则依赖镜头的景深，同时在楼房爆炸的地方加入了一个缩小了的爆炸素材，以及爆炸的辉光效果，和重新放置的前景物体，整个的镜头接着匹配时间用来做最后的剪辑制作。
