nember meaning in English
南贝尔
Examples
- The nember of the students in their school is over one thousand
他们学校的学生人数超过一千。 - First , the current optical system construction ' s optimization algorithms are based on the just optical system ' s preliminary construction which designers have selected . optical system program can not automatically change the optical elements ' nember . so that optical system design ' s intelligentized degree is not high . now this paper applies the genetic algorithms to lens design and shows that the genetic algorithms can effectively work in automatically changing the optical elements ' nember . next , this pape present a new computer design method that applies the genetic - simulated annealing algorithms to directly design the binary optical element
首先，由于现有的光学系统结构设计的优化算法都是在选定了初始光学结构的基础上，只对光学结构参数进行优化选择，在优化过程中不能够自动改变光学面数，导致光学系统设计的智能化程度还不是很高，采用遗传算法，实现了光学面的自动增减；其次，区别于传统的二元光学设计方法，为避免其量化台阶数过大导致的成本及加工复杂度的增加，提出了运用混合优化策略遗传-模拟退火算法直接设计二元光学元件的新的计算机方法。 - On views separation and coordinate standardization , a coordinate axis projection - based approach and an image scanning - based approach are proposed for views separation , the former reduces the compare times of 2d primitive in drawings and raises the efficiency simultaneously , the latter can separate free nember views of engineering drawing accurately and it has no correlation with complexity of primitive , then , two sets of 2 . 5d coordinate systems are introduced as intermediates to relate the 2d original drawing system to the 3d space projection coordinates anfd a formal technique is developed for constructing transformation matrices between coordinates
3 .在工程图视图分离和坐标规格化方面,提出了改进的坐标轴投影分离算法和基于图像扫描的视图分离算法。前者减少了工程图中二维实体的比较次数,提高了运行效率;后者可以准确分离具有任意视图数目的工程图,且算法的稳定性与边界复杂度无关。通过引入二维半中间坐标系推导出了从绘图坐标系到空间投影坐标系转换的转换算子并给出了基于转换算子的坐标规格化算法。
