查询词典 Shutter

Louis Daguerre in France made the first practical version of the silver camera, which is composed of two wooden boxes, insert a wooden box to another box in focus, shutter used as a lens cap, to control for more than 30 minutes of exposure time, can be taken a clear image.

1839年，法国的达盖尔制成了第一台实用的银版照相机，它是由两个木箱组成，把一个木箱插入另一个木箱中进行调焦，用镜头盖作为快门，来控制长达三十分钟的曝光时间，能拍摄出清晰的图像。

Based on the analysis of both home and abroad status quo of virtual assembly, this paper investigates the software and hardware architecture of virtual assembly system in network environment. It develops VR hardware interfaces based on Java platform, such as data glove, 3D position tracker and shutter glasses, etc.

论文在分析国内外虚拟装配技术研究现状的基础上，较为深入地研究了网络环境下虚拟装配系统的软硬件体系结构，设计了虚拟现实硬件如数据手套、三维位置跟踪仪、闸门式立体眼镜等设备的基于Java平台的接口，实现了立体显示、虚拟手抓取操作等功能，进行了虚拟环境中的碰撞检测。

2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.

给出双反射系统杂散光消除设计的具体要求，结合作图法，推导出考虑视场大小及初始中心遮光比确定时，主次镜内遮光罩顶点坐标公式；讨论考虑渐晕时主次镜内遮光罩的设计；为了减小初始中心遮光比，将次镜锥状遮光罩改进为百叶窗式结构；设计在杂散光源抑制角已知时的外遮光罩，并利用C语言实现程序化设计其挡光环的方法；设计主、次镜间镜筒内壁上等高挡光环，进一步抑制双反射系统的杂散光。

Drencher for rolling shutter: 0.5L/s.m, fire duration time is 3h

卷帘水幕用水0.5升/秒。米，火灾延续时间为3小时

The research about the critical technique includes: developing the radiation-hard CCD sensitive to the X and EUV ray; implementing the design of CCD driving clock and signal readout electronic using CPLD; implementing shutter design which can realizing 1ms - 10s exposing time.

关键技术突破包括：完成X射线和极紫外波段都敏感的抗辐照型CCD技术设计，并利用CPLD实现了非规则像素阵列CCD的驱动时序和读取电子学电路设计和调试：完成1ms～10s宽动态范围快门装置设计和调试。

The camera is provided with electromechanical program shutter controlled with electronic exposure meter ensuring automatic working of exposures.

如今玩Pola的人说，玩Pola就是为了及时分享拍摄带来的快乐。Pola最吸引人之处也在于此。

Set f-number on 7,0, shutter speed on 45, and film speed on 50. And here we got.

把焦距设置成7.0，快门调到45，还有胶片速度50，在看一下。

Next thing we need to do is to create vraycamera, this is very important, because without this type of camera we wouldn't get options like ISO, shutter speed, f-number.

下面我们要做的是建立一个物理相机，记住这是非常重要的，因为只有物理相机有iso，shutter speed，f-number这些选项。

Example3:Exposure control:film speed Exposure: on, Shutter Speed (s^-1): 60.0, f-number: 8.0, Vignetting: on, White balance: white

这项参数决定了图像对光的灵敏性-感光度。如果胶片速度值较高那么图像将会对光线更为敏感，图像也就越亮。

Example8: White balance Exposure: on, f-number: 8.0, Shutter Speed (s^-1): 200.0, ISO: 200.0, Vignetting: on

举个例子：在日光场景中可以使用桃红色来校正阳光的颜色。

As of Tuesday, Google's results were still censored in China.

截至周二，谷歌的搜索结果仍受中国审查。

In order to make the positive action increase and negative one decrease, the sub-forces of the social factors must be adjusted to form a centripetal force.

在这一过程中，人的主体性发挥是社会有机体健康发展的灵魂。
