volumetric density meaning in Chinese

体积密度

In conclusion , solid immersion lens , which is feasible to focus femtosecond laser pulse in three - dimensional optical data storage , shows the rather potential to increase the volumetric density
总之，用固体浸没透镜在透明介质中进行飞秒激光三维存储是可行的、且其在提高体存储密度方面有较大的发展潜力。
The feasibility and some advantages of employment of sil have been discussed . the numerical aperture are calculated when laser pulse is defocusing . in contrast with traditional microscopy objective , the employment of solid immersion lens can effectively increase the numerical aperture of the recording system ; thereby it can increase the volumetric density and decrease the demand of the incident laser power
当脉冲聚焦点相对于固体浸没透镜底面离焦时，对系统的有效数值孔径进行了计算，结果表明采用固体浸没透镜离焦的方式进行记录，系统的有效数值孔径最低可增大到固体浸没透镜插入前的折射率倍，其数值孔径的理论极限值为存储介质的折射率。
