  1. On the other hand, the hydraulic performance of the hole, including flow rate coefficient and uniformity of flow rate, have been tested as standards to evaluate the quality of holes punched by laser drilling machine with much better results than that punched by mechanical drilling machine. the shape of holes taken by a microscope photograph can also give detail and well explanations for this test results

    對噴孔水力學性能的試驗研究表明,本文提出的用噴孔水力學性能指標(流量系數和流量變異系數)來評價微噴帶激光打孔機質量的方法是可行的,並證明微噴帶激光打孔機的質量明顯優于機械打孔的質量,用顯微鏡觀察噴孔的形狀的照片也同樣證明了這一點。
