稳态磁场对激光熔凝熔池的抑制作用研究

王梁[1], 胡勇[1]
[1]浙江工业大学，杭州，浙江，中国

激光熔凝通常被作为材料表面的最终处理工艺，然而激光熔凝处理后，材料表面容易出现高低起伏的波纹，降低了其表面质量。因此，为了在激光熔凝处理后获得平整的表面，同时降低后续机加工所需的成本和时间 ... 扩展阅读

关于气泡在LIMCA系统中变形的数值模拟

杨文志[1], 王晓东[1]
[1]中国科学院大学，北京，中国

LIMCA技术是一种原位测量高温液态金属中杂质颗粒的方法。测量的原理为：在一个小孔内外设置一对电极，并且通以电流，这样可以在孔口附近形成一个电敏感区，当杂质经过电敏感区时，通过测量电压脉冲信号以检测杂质的信息 ... 扩展阅读

Sound Cavity Acoustic Resonance Analysis of a Microspeaker/微型扬声器音腔声谐振分析

Z. Zhang[1], X. Deng[1]
[1]Jiangxi Lianchuang Hongsheng Electronic Co.,LTD, Nanchang, Jiangxi, China

移动电话产品向更薄的趋势发展，装入手机中的微型扬声器能使用到的音腔空间也就日趋减少。为了高效利用手机内部空间，手机音腔设计时往往导通扬声器位置周围的小空间作为其音腔，扩大音腔体积。与此带来的问题是，因手机内部空间限制 ... 扩展阅读
