A team from Romania and Japan has now demonstrated a system that can focus two or three laser beams into an engine's cylinders at variable depths.
一个来自罗马尼亚和日本的团队现在已经证明了一种系统，这种系统可以在可变深度上将两三束激光聚焦到发动机汽缸里。
This variable contains the ID of the control that has the focus and was registered using IFocusService.
此变量包含拥有光标焦点的控件的ID，该控件使用IFocusService注册。
That is, it's hard to identify patterns and integrate higher-level behavior when your focus is narrowed down to the size of a source line or a variable.
当您将关注的焦点集中于一行或一个变量时，它很难识别出模式并综合高级行为。
A new style of flexible focus variable mirror which is forced by piezoelectric ceramic is designed in this paper.
设计了由压电陶瓷施压的柔性变焦镜的结构。
Placing a diffractive optical element(DOE) on the incident laser beam to improve the depth of focus, the DOE'S aperture is variable.
在入射光束的孔径受限制的情况下，利用衍射光学元件来增加激光束的焦深。
