两次曝光

In the double exposure hologram recording process, the sub-surface material placed before the mirrors for micro-wave displacement, then the mirror reflection of the reference beam ...

在两次 曝光全息图的记录过程中，置于物面的分波前反射镜作微位移，则该反射镜反射的参考光。。。

The spectrum of fiber Bragg grating can be controlled by double exposure technique. The first exposure is used to control the resonant wavelength of fiber grating by directly irradiating the naked photosensitive fiber.

该方法只使用普通Bragg位相模板，采用两次曝光技术，通过控制光纤光栅的本地谐振波长和反射率，达到控制光纤光栅谱形的目的。

The present invention makes it possible to make sample fiber grating with variable or fixed period simply and reliably.

控制了两次曝光的时间间隔，便可以控制取样周期；控制了曝光时间，便可以实现变占空比。

And latter by for many times the BMW of exposure downloads implement, script downloads implement series, newer frequency achieves semidiurnal above actually, rolled out technically still avoid kill a technology.

而近来被多次曝光的宝马下载器、脚本下载器系列等，更新频率竟然达到一天两次以上，还专门推出了免杀技术。

Using SPIV technique's photographic method,CCD camera was placed on a three-dimensional positioner system,took two photos from two directions of this holograms,andobtained two directions'particle images for three-dimensional calculation.

采用体视PIV技术中正直摄影方法，将一个CCD相机安装在高精度的位移机构上，从全息图再现象的两个方向拍摄，获取同一切面两个不同观察方向的两次曝光粒子图象，从而实现三维速度重建。

Experiments show that this technique can effectively extend the gray dynamic range of Xray image without increasing patient dose.

实验表明，该方法能有效扩展图像的灰度动态范围，并且两次低剂量曝光并未增加患者皮肤表面吸收剂量。

It was late in the summer, a quiet morning in Coney Island, and my initial idea was this: replicate the cover of Strictly Business, only with a double-exposure shot of Steph sitting on both cars.

那个夏天快要结束了，康尼岛上迎来了一个安静的早晨，我最初的想法是：模仿电影《登龙妙着》海报封面的风格，用两次曝光的方法拍一张史蒂夫坐在两辆车上的的相片。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
