Technical characteristics: concavo-convex Nano-imprint lithography processing is a common business card printing and membership card making products that decoration, he uses the Teletext match concavo-convex stempelsysteme, by mechanical action make printing surface correspond to the Office of the permanent press deformation occurred in oilysludge, in the printing surface stereo pictures and texts, in recent years with the electronic sculpture and laser engraving technique, concavo-convex stempelsysteme mismachining standard qualitative leap, given the drlling of concavo-convex stempelsysteme makes it possible for the processing of via concavo-convex Nano-imprint lithography printed matter is more true to life on the surface of the graphics and text.

工艺特点：凹凸压印加工是一种常见的制卡和会员卡制作品表明装饰工艺，他使用图文信息相互匹配的凹凸印模，通过机械作用使印品表面对应处基材发生永久性挤压变形后，在印品表面形成立体图文，近年来随着电子雕刻和激光雕刻技术的不断提高，凹凸印模的加工水平有了质的飞跃，精雕细凿的凹凸印模使得经凹凸压印加工的印品表面之图文更加惟妙惟肖。

In order to study the influence of UV pulse laser pre-treatment on surface image of fused silica and validate its upgrade effect on anti UV laser damage ability of fused silica,using 355nm YAG laser raster to scan fused silica optics by means of power increase by degrees periodically,the change of surface image was studied and its anti-laser damage threshold at 355nm was measured.

为了研究紫外脉冲激光预处理对熔石英表面形貌的影响，验证其对熔石英元件抗紫外激光损伤能力的提升效果，利用输出355nm 3倍频紫外脉冲激光的YAG激光器，采用光栅式扫描的方式对熔石英表面进行了全口径能量周期递增的激光预辐照处理，并在处理结束后研究了表面形貌的变化，考核了其在355nm脉冲激光作用下的损伤阈值。

Scanning electron micrograph results showed no surface rupture either on garlic skin or garlic kernel by sodium alginate solutions. It also indicated tubular texture for the surface of garlic skin, and sponge-like structure for the surface of garlic kernel, respectively. Average surface roughness by magnetic force microscopy were under 57 for garlic skin, and under 13 for garlic kernel, respectively.

扫描式电子显微镜影像观察可知海藻酸钠薄膜溶液涂布后皆不会对蒜皮或蒜仁表面造成破坏，并且发现蒜皮表面较为粗糙之维管组织，相对於蒜仁表面较平滑之海绵薄壁组织。

It was found that the mechanical properties of the joints decreased by the alclad and it will be increased dramatically by removing the alclad. The effect of alclad on the bottom surface is larger than on the top surface. The mechanical properties of 2024-T3 joints will fall down because alclad is entrapped into the welded joints by the rotating and stirring tools during the friction stir welding, similar with "inclusion" in fusion welding.

研究结果表明，包铝层的存在明显降低了2024-T3铝合金搅拌摩擦焊接头的力学性能；去掉包铝层后接头的性能显著提高；下表面包铝层对接头性能的影响大于上表面包铝层；当2024-T3铝合金表面带有包铝层进行搅拌摩擦焊接时，在搅拌头的旋转和搅拌作用下，包铝层被卷入焊缝中，形成类似于熔焊的&夹杂&，从而使得接头的力学性能下降。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.
