needle-density

The result shows that areal density has more effect on insulating ability than needling density and needling density has more effect on peel bond strength,and the processing technology is designed according to it.

通过实验研究了面密度和针刺密度对保温性能和剥离强力的影响。

The relationship between needling density, the depth of needle penetration and the properties of nonwovens, such as basic physical properties, mechanical properties and filtration properties is analyzed thoughout experiment and theory analyses.

经实验验证及理论分析 ,得出了针刺密度、针刺深度与非织造布物理性能、机械性能及过滤性能的关

A new algorithm using density pointer is proposed to initialize cluster centers.

提出了一种采用密度指针的聚类中心初始化方法——density pointer(DP)算法。
