有孔膠片 的英文怎麼說
中文拼音 [yǒukǒngjiāopiān]
有孔膠片
英文
perforated film-
Due to the size of the defect, a fragment of bone is introduced to support the mucosal graft. strength of the repair is verified by increasing intercranial pressure with the valsalva maneuver, and it is seen to be watertight. rapid - setting fibrin glue is applied, and a second layer of mucosa is applied over this
由於瘺孔較大，置入一些骨的碎片以支持填塞物，通過valsalva法咽鼓管吹氣法增加顱內壓可以觀察修補的牢固性，可以看到沒有泄漏，利用可以快速固定的纖維蛋白膠進行固定，其上鋪上一層粘膜，然後再用膠水進行固定。In the experiment, we use the he - ne laser and the semiconductor laser as the source, record the bessel beam patterns behind the axicon by using a digital camera and a microscope, measure the radius of the bessel beam central spot by film - scanning and measure the effect of both the radius of the aperture and the open angle of the axicon on the maximum non - diffraction distance. the experiments show that a specific propagating range has constant power and the beam has a bessel - like distribution in this range. the results agree with the beam corresponding to a diffraction free beam
同時我們還採用膠片掃描的方法測量了無衍射光束的中心光斑尺寸，測量了不同光闌孔徑和不同稜角情況下的最大無衍射距離和傳播軸附近橫截面內微小光孔中的光強，實驗結果顯示當激光光束經過軸棱錐轉換後有一段距離功率變化很小，且分佈近似貝塞爾分佈，符合無衍射光束的特性;經過聚焦后，呈現三維分佈中空的光束bottlebeam ，實驗結果與理論分析基本吻合。Yiwu jufeng plastic co, ltd is professional manufacturer specializing in all kinds of plastic bags, like micro perforated wicket bread bags, flower bags, transparent pvc handbags, cosmetic bags, hot melt self seal bags, pp clothes bags, opp self adhesive bags, gift bags, courier bags and other plastic packaging bags
