查询词典 shutter weir

The quarter ellipse curve is used at upstream face of weir crest and intake side of surface hole, the downstream face of weir is linked with 1:0.7 slope section, then linked with ogee spillway, its radius is equal to 30m.

表孔堰顶上游坝面及进口侧采用1/4椭圆曲线，堰面下游接1：0.7的斜坡段，再接R=30m反弧段，并采用长隔墩布置方案。

Effects of weir-dam combi- nation, gas curtain instead of weir or dam on fluid flow characteristic were compared in detail.

比较了传统堰坝组合，吹氩气幕挡墙分别代替堰、坝对中间包流体流动特征的影响，并尝试在中间包内采用双气幕挡墙的控流方式。

For the structure that the side-frusta is also used as retain wall,considering the side frusta fastened on the weir body,the plane stress is calculated at first. Then the moments,horizontal shear force and vertical force on the bottom of the retain wall are applied as fixate,and stress distribution on the weir body are calculated piecewise.

对于边墩兼作挡上墙结构，通常是将边墩视为固端于岩体上，先进行下端为固端的挡墙平面受力计算，再将挡墙下部的弯矩、水平剪力和垂直力作为集中外荷载进行堰体的应力计算，堰体也只能分段进行片面受力计算。

A measurement method of effective exposure time on curtain shutter is raised,which is based on analysis and calculation of effective exposure time on aerial camera shutter.

为评测卷帘式航摄快门曝光时间的均匀性，根据有效曝光时间的分析计算，提出了一种可变缝宽式快门有效曝光时间均匀性的测试方法。

Although factors that affect the quality of an image captured at high speed include scene luminance, aperture size (f-number, f/#), shutter speed, and field of view, a simple calculation can determine the approximate shutter speed needed for such an application.

尽管影响高速捕捉图像质量的因素包括场景的亮度、镜头大小、快门速度和视野，不过对于这样的应用场合可以很简单就计算出大致所需的快门速度。

If your shutter speed is fast (eg 1/4000th of a second) it's not going to see much movement (unless the the subject is moving mighty fast) while if you select a longer shutter speed (eg 5 seconds) you don't need your subject to move very much at all before you start to see blur.

如果快门速度较快（以1/4000s为例），看不到较多的动态，如果你选择了较慢的快门（5s），要让目标物体模糊，你不需要运动物体移动很快。

The electroplated ferronickel shutter is suspended by a silicon spring The shutter is fabricated by the nonsilicon surface micromachining techniques. The planar coil is fabricated by high-aspect-ratio photolithography and mask-plating processes. And the silicon spring and the fiber alignment components are fabricated by the reactive ion etching and by the silicon anisotropic etching process.
