n.挡板(减音器；折流器；节流阀)
Solid bulk cargo must be strictly trimmed until to ambient bulkhead.If not enough, then heavy cargo package and baffler shall be supplied. 固体散装货物必须严格平舱，一直平整到货舱四周舱壁，如果对稳性还有严重影响，则再加压包和挡板措施。
Second process: After operated by the front forward gas baffler, the paper reciprocates to the drum of the second layer to perform flanging of the backside. 第二个过程：纸张经前推气挡板之作用，再往复至第二层滚筒完成后边折边。
Third process: After operated by the back forward gas baffler, the paper reciprocates to the drum of the third layer to perform flanging of the front side. 第三个过程：纸张经后推气挡板之作用，再往复至第二层滚筒完成前边折边。
Being sealed on the isolation piece, the baffler forms closed area in advance.Thus, the invention raises reliability of image module assembled, and ratio of fine product. 由于本发明打线区上设置隔绝件，再将阻隔板封合于隔绝件上，先形成封闭区域，因此在组装时，本发明可提高影像模块的可靠度，进而使良率提高；
Compared with flat-bottomed aerator, the impact angle of the aerator with a downstream baffler was smaller and it has better aerated effects than the one without downstream bafflers. 结果表明，相比于常规平底掺气设施，平底下游加设贴坎掺气设施射流冲击角较小，能有效地抑制空腔回水，有稳定的掺气空腔，且通气量等掺气特性指标都有明显改善。
