diameter of hole meaning in English

最大孔径

The required porosities for various cases were obtained through varying the diameter of holes and spacing among the holes
各物理模型通过改变气膜孔径大小和孔间距得到不同的孔阵排列疏密度。
The diameter of holes in porous - layer alumina is about from 50nm to loonm , and the distance between holes is about from 100 nm to 150nm
其中阻挡层氧化铝和多孔层氧化铝构成纳米氧化铝模板。纳米氧化铝模板中孔的大小约为50 100nm ，孔间距约为100 150nm 。
The relationships between the laser performance index , such as laser power densities , pulse energy and energy densities , and the diameter of holes have been set up , and a experience formula between the energy density and the diameter of holes has been established by the regression method , based on the experiment results
在此基础上，本文对微喷带激光打孔机的性能进行了试验研究，得到了激光功率密度、激光脉冲能量和激光能量密度对打孔孔径的影响关系。通过数据回归的方法，建立了激光能量密度与孔径之间的半经验公式。
