椭圆化 meaning in Chinese

ovalization

A theoretical and experimental study of a new , efficient technique to couple a laser , emitting a highly elliptical beam , to a single - mode fiber without the use of bulk optical components is presented . the technique involves butt coupling the laser to a cylindrical lensed fiber and spherical lensed fiber
本文从理论上和实验上呈现了一个实用的耦合技术，即在没有使用分立球形光学元件的情况下将高度椭圆化的激光光束通过透镜光纤耦合到单模光纤中。
The sintef work indicates that it is possible for the increased flexibility due to ovalization of the bend to be more than compensated for by a large increase in the wall thickness of the bend , with the result that the global flexibility factor could be less than 1 , i . e . the bend is stiffer than the pipe
试译如下： sintef的文件表明由于弯管椭圆化所增加的挠度可能更容易被弯管壁厚的较大增量所抵消，从而整体挠曲系数会小于1 ，如果弯管硬度大于管道硬度。
