So the idea here is that the ants are working so hard to hang on to the wall or the floor or whatever you call it that they're less likely to interact, and so the relationship between how crowded they are and how often they meet would be messed up.
这个实验的想法是 蚂蚁要花大力气把自己挂在墙上 或者也可以说是地板上, 你怎么看都行 这样它们就没有精力去交互了, 所以关于蚂蚁密度的信息 以及它们相互遇见的频率 都会乱掉.
