| 中文摘要: |
| 为了促进自动变光焊接液晶光阀的发展与应用,对其响应特性的研究就变得非常有必要.在对光阀的光透射比和遮光号进行研究的基础上,提出了对响应特性中响应时间和保持时间的精确定义.通过对不同标准中不同测量方法的比较,确定了对其响应特性的精确描述. |
| 英文摘要: |
| To facilitate the application and development of the automatic welding filter,it is necessary to study its response characteristics.On the basis of the analysis and research about luminous transmittance and the scale number of the filter,this article proposes a solution to the specific definition of the response and holding time.By comparing different calculation methods in different standards,a felicitous way is chosen to describe the response characteristics accurately. |
