以单元密度为设计变量，材料用量为约束，以结构最小柔顺度为目标函数。

The density of elements was designed with theamount of the materials. The objective was to reduce flexibility of thestructure.

然后将“贡献度”作为网格单元密度，使用密度阈值函数来定义网格的密度阈值进行聚类。

Then the Contribution is the grid density and dispose of density threshold of grid by the method of density threshold.

尽管这些图像没有彻底展示显示器的高分辨率，但是您可以从许多屏幕单元中的文本密度看到高分辨率。

Although these images don't quite demonstrate the high resolution of the display, you can see it in the density of text in many of the screen cells.
