Through image digitalization and digital image frame analysis, the dynamic change of arc state and droplet motion before and after its detachment from wire tip can be quantitively described. The kinematical and kinetical parameters of droplet motion can be solved. The development of the system provides a new way for the study of metal transfer mechanisms and the interaction between droplet transfer and weld pool.

该系统通过对高速摄影图象的数字化处理及时间图象序列分析,可以对熔滴过渡过程中电弧变化的动态过程及熔滴脱落前后的运动过程进行定量分析,并可提取出熔滴运动的各种运动学和动力学参数,为进一步的熔滴过渡机理及熔滴与熔池相互作用的研究提供了新的研究手段。

The results show that the main CO proliferation forms in coal bed are the Knudsen proliferation and the transition proliferation.

结果表明,CO在煤层中的扩散主要为Knudsen扩散及过渡型扩散方式,过渡孔的增加有利于其扩散,而微孔的增加则不利于其扩散。

Martha Bigelow, Letitia Basford and Esther Smidt.(2008)."Supporting Hmong Newcomers' Academic and Social Transition to Elementary School."
