扫描轨迹 meaning in English

scanning trace

In this thesis , the 2 dimensional ( 2d ) and 3 dimensional ( 3d ) models of the sls of 316 stainless steel powder were constructed . apdl ( ansys parameter design language ) was used to control the density of thermal flow , velocity and path of scanning
本文建立了316不锈钢粉末激光烧结的二维、三维模型;运用apdl语言控制热源的热流密度、移动速度以及扫描轨迹;研究了单层多道和单道多层烧结的温度场和应力场。
Abstract : in this paper ， a ray - optics analysis is performed to investigate the asymmetry of dual beam scanning field produced by a rotating polygon . some basic equations of dual beam scan are derived ， such as ， the position vector for the incident point ， the scalar expression for reflected ray ， scan pattern on observation plane ect . the far - field asymmetry of the scanning field has been discussed
