At the same time, some design and construction Suggestions of strengthening beam in joint zone what can be a reference for most engineering technologists are given.

同时，针对节点区梁端的加固设计和施工提出了建议，供工程技术人员参考。

The results show that diffraction efficiency of a lossless grating increases with the higher ratio of reference beam width to object beam width.

对于无吸收的光栅，参考光束相对物光束越宽，衍射效率将越高。

If a beam similar to the original reference beam is shone through a hologram, the result is a three-dimensional image of the object scanned.

ECONOMIST: Researchers can now broadcast moving holograms

When the reflected object beam and the reference beam are recombined, they create an interference pattern that encodes the 3-D image.
