质量函数 meaning in Chinese
mass function; quality function
Examples
- So quality functions are presented to define wrinkle , flat area , fracture and springback tendency etc
为此，本文提出了质量函数的概念，并对起皱、平台区、破裂及回弹等常见缺陷进行了定义。 - The number density distribution of globular cluster in space will change with time due to the dynamic evolution , especially for those in the central region of the galaxy ; 5 . for the power law initial cluster mass function , the peak value of the mass function after the dynamic evolution is sensitive to the lower limit of the initial mass function we adopt . the suggested value in this paper is - 104m , which is consistent with that reduced from the dynamical analyses for the giant molecular clouds
对于幂率的初始质量谱，球状星团系统动力学演化后质量分布的转折点质量主要是由初始质量函数的质量下限决定的，最为适合的值为10 ~ 4m _ ；幂率的初始质量谱的谱指数对球状星团系统动力学演化后质量分布的转折点质量也有影响，其最佳值为1 . 5 2 . 0 ；经过大约5gyr的动力学演化，幂率的初始质量谱就会演化成为高斯的对数质量分布并具有在随后的动力学演化中保持对数高斯形式质量分布的特性。 - The global normalized ants - seed pheromone update rule is presented to ensure that the sum of the pheromone distributed over the construction graph is a constant , in addition , the normalized mechanism solves the problem of pheromone initialization and avoids the influence of the scale of the quality function of the solution
本章还提出了一种全局归一化的的蚂蚁种子信息素更新规则，该规则能保证分布在整个解构造图上的信息素的总量保持恒定，同时解决了信息素初始化的问题以及消除了解质量函数的量纲对算法性能的影响。
