During horizontal adjustment of the cutting plane, the level can be adjusted at any time according to the requirements of the cutting plane, which overcomes the shortcoming that the platform cannot be

此机的切割平台装置多组水平调节机构，在切割平面水平调节中可随时根据切割平面的要求、调整调节水平，克服了切割机出厂后不能再调节平台的缺点。

As a miniaturist and model maker, this tool has been invaluable for cutting one or a myriad of small parts at various angles and sizes -- to change the angle you slide a self-indexing metal guide that runs perpendicular to the blade.

如果你是微图画家或者模型制作者，这种工具对于各种各样角度和大小的小零件的切割——无论是单个切割还是大批量地切割都是至关重要的。如果要改变角度，你只需滑动垂直于刀刃的金属制成的指示器。

This article is focus on the design of a real-time embedded control system for online laser cutting of packaging paper.

本文主要论述了一种用于激光切割控制的实时嵌入式系统的设计过程，该激光切割系统主要用于包装纸的在线切割。

The experiments showed that both rotary belt cutter and the jagged chain cutter can realize high speed cut with high ground speed, the former cut speed and operating speed can reach 17 m/s and 15 km/h separately, and the latter can reach 7 m/s and 13 km/h responsively.

试验表明，回转带式切割器和齿形链式切割器均可实现高速切割和高速作业，前者(来源：ABC55论文网www.abclunwen.com)的切割速度和作业速度分别达17m/s和15km/h，后者的切割速度和作业速度分别达7m/s和13km/h；工作平稳，割台振动小，割茬整齐，无撕裂、漏割、重割和堵刀现象；适于收割小麦、水稻等细茎秆作物和牧草。

However,the princess cut is not a modification of the step cut diamond, but of the brilliant cut .

尽管如此，公主方形切割并不是阶梯形切割的改良，而是明亮式切割。

Phase correlation and then reaches image mosaic by graph cut and poisson image fusion.graph cut is used to find a globally optimized seam-line for deghosting while poisson image fusion is used to realize smooth mosaic without exposure difference.a new weight calculation method based on the statistics of guadient direction histogram is presented here in order to robustly realize graph cut.an edge transition poisson image fusion method is also proposed to reach exposure difference removal

该方法在相位校正的基础上将图切割和泊松融合相结合实现拼接，图切割用于搜索全局最优的缝合线以去除鬼影，泊松融合用于曝光差异的处理。本文给出新的基于梯度方向直方图统计的权值计算方法，实现稳定的图切割。另外，本文还设计出重叠过渡的泊松融合方法，较好地完成图像合成。
