1) minimum beam waist
最小光斑
2) minimum polygon
最小图斑
1.
By use of the rapid assessment approach of soil erosion based on minimum polygons,a case study is conducted in the Yellow River basin where serious erosion is occurring.
在前期研究的基础上,将基于最小图斑的土壤侵蚀快速评估方法应用到黄河流域土壤侵蚀的评估中,建立了土壤侵蚀特征指标(EI)与土壤侵蚀强度E之间的判别分析关系,并根据判别函数判断EI的归属类别,从而获得每个图斑的土壤侵蚀强度。
2.
In view of the limitations of the traditional models in applications in different temporal and spatial scales,this paper presents a rapid soil erosion assessment approach based on minimum polygons.
本文通过引入快速评估的思想,基于遥感监测数据和最小图斑,建立了土壤侵蚀快速评估模型。
3) Small optical beam method
小光斑法
4) size of light spot
光斑大小
1.
The relationship between angle errors outputting from a quadrant detector and its area and location,size of light spot was analyzed deeply,which shows that the shorter radius of light spot the better testing precision of angle errors,and the longer radius of light spot the bigger linearity span of angle errors.
从与误差信号测量误差关联的原理误差及与信噪比SNR有关系统误差出发,提出了光斑大小优化设计的问题,得出实际设计的光斑大小稍大于探测器有效半径的1/2有助于改善系统性能,并通过相关系统研制稳定性跟踪试验给予验证。
