大伙房水库输水(二期)工程取水口型式独特,结构异常复杂。因工期调整需要,闸墩混凝土浇筑由原计划常规翻升模板改为滑模浇筑,通过技术攻关,高效、优质、安全地完成了取水口闸墩混凝土浇筑任务,压缩直线工期3个月,经济效益显著,为后续项目的施工争取了主动。

表面等离子体激元具有近场增强效应,可以代替光子作为曝光源形成纳米级特征尺寸的图像.本文数值分析了棱镜辅助表面等离子体干涉系统的参量空间,并给出了计算原理和方法.结果表明,适当地选择高折射率棱镜、低银层厚度、入射波长和光刻胶折射率,可以获得高曝光度、高对比度的干涉图像.入射波长为431nm时,选择40nm厚的银层,曝光深度可达200nm,条纹周期为110nm.数值分析结果为实验的安排提供了理论支持.

为了使服装教学适应企业自动化、数字化和智能化需求,本研究以方形贴袋为例,利用常规缝制法和3种不同模板制作法进行比较。研究结果表明:智能化模板制作工艺方法所需时间更短,成品效果更好,大大提高了制作效率,降低了产品对操作者技能水平的依赖;同时也发现针对不同的面料性能和需求应采用不同的模板,才能更好地操作,进而提高制作效率和工艺效果。
