讲理论

In chapter 3, characteristic paraments, focusing structure were discussed, the processing of double cell for phase conjugation was analyzed. Designing criteria of double cell phase conjugation mirror was given out. All phase aberrations could be compensated by using phase conjugation theoretically, but compensation is only effective to phase aberration of uniform polarizing state, it is not effective to aberration by thermally induced depolarization an diffractive effecting by aperture.

在第三章，我们讨论了SBS介质的特性参数，相位共轭镜的聚焦结构，分析了双池相位共轭镜的相互作用过程，给出了相位共轭镜的设计原则；从理论上讲相位共轭技术可以完全补偿热畸变以及因各种光学不均匀性造成的光束畸变，但是相位共轭技术只对偏振态均匀的相位畸变造成的光束畸变起补偿作用，而对由于热致双折射效应造成的退偏以及光束通过硬边光阑时的衍射效应造成的光束畸变无能为力。

This article has studied HG70 steel and HS-70 welding wires weldings,the welded joint,welding quality,and the welding operational performance,in restricts under the welding condition,Uses HS-70 welding wires,Experiments the steel plate the weld joint stretch,degree of hardness and the resilience test result indicated that,HG70 steel and HS-70 welding wires weld joints have the low crack sensitivity,The welding quality is good,Its weld joint has the fine mechanics performance,thus explained they had the fine welding match.

0前言非调质钢具有优良的使用性能和较低的生产成本，受到普遍重视。HG70钢是武钢开发的工程结构用钢，具有强度高、低温韧性好的特点。传统高强度钢一般碳当量较高，焊接性能较差。通过加入微量合金元素、采取新的控轧和调质工艺，使得HG70钢在提高强度的同时，亦保持了较高的韧性和较低的碳当量，因而从理论上讲HG70应具有较好的焊接性能，但HG70钢与HS-70焊丝的匹配情况，还有待于分析验证。

However a great deal remains to be done in terms of theorising what this whole experience of 'embedding' in war has to tell us about the increasingly blurred lines between journalism and public relations, about media/military relations, about the changes to television news coverage and to the very definition of 'news' being brought about by new technologies, and about differences between journalism practice and 'what the audience wants'.
