large cone meaning in Chinese
大钟
Examples
- A varying - temperature etching method for fiber tip preparing was proposed , with which fiber tips with cone angle as large as 35 - 52 degree could be routinely made . to explore the mechanism of varying - temperature method the changing of the diameter of a fiber during etching process was carefully measured and an experiential formula was found . it reveals that the etching rate of fiber keeps constant until the diameter reduces to a certain amount , which explained the large cone angle obtainable with varying - temperature method
在光纤探针制作方面，本论文提出了一种变温腐蚀制备光纤探针的新方法，获得了35 52度的大锥角光纤探针；进一步对光纤探针腐蚀成形过程进行定量研究，发现当光纤直径腐蚀减小到一定程度以后，腐蚀速度随直径变小而加快；通过对多次实验结果进行拟合，得出了光纤直径随腐蚀时间变化的定量经验公式；借助该经验公式从理论上定量模拟了变温法获得大锥角针尖的过程。
