25mm
3.The stem thi ck was 1.5mm and wide 5mm,The length was variety:25mm,30mm,35mm,40mm,60mm,80mm,100mm,120mm. There were three to six poles i n the bar. Pole diameter was 2mm.
4.ventilator gauge 80*80*25mm, wind cover diameter 110mm, vent was on top;
5.Of 131 lesions, the CPM diameter less than 15mm was seen in 44, between 15～25mm in 66, 25～40mm in 17 and larger than 40mm in 4. And the wall thickness of the cavity below 4mm, between 4～15mm and over 15mm was respectively seen in 69, 44 and 18 CPMs.
6.The Interior Ballistic Analysis and Configuration Design of the 25mm Bore Hypervelocity Launcher
9.The ?25mm measurement area adopted by Drayton Method exerts far-reaching influence on the quenchant′s flow rate,thus ?50mm measurement area is highly recommended.
10.According to the gestational sac diameter,those patients were divided into three groups:less than 20mm,from 21 to 25mm and more than 26mm. There was no statistical difference among the three groups(P>0.05).
