之后包括模板和细胞立方体在内都要用聚乙二醇再次包被，后者作为粘合剂使立方体块紧密相连并牢牢地固定在支架表面。

Both template and cell cubes are coated again with the PEG polymer, which ACTS as a glue that holds the cubes together as they pack themselves tightly onto the scaffold surface.

每个机器人都由多个10 cm大小的立方体组成。这些立方体具有同一的部件、互相连接或分离的电磁石和计算机复制程序。

Each robot consists of several 10 cm cubes which have identical machinery, electromagnets to attach and detach to each other and a computer program for replication.

和球形“地球”具有同等体积的立方体的每个边长应当是10000公里，每个顶点到立方体中心的距离是8700公里！

A cube with the same volume as the spherical Earth would have a side 10, 000 km (6, 400 miles) long so the corners are 8700 km from the center!

So in order to fill them, he would have to have eight electrons or an octet around the cubes.

因此为了填满它们，他必须放上八个电子或者说一个“八隅体“,在立方体周围。

So, basically what he's showing in these cubes is that there are eight spaces that need to be filled up to have a full cube.

因此，基本上他在这里展示是这些立方体中一共有,八个位置，需要把它们都填满才得到一个完整的立方体。

So, let's go back to the notes, and let's fill these in, seven electrons. Another way you could have known them was to look at Lewis' notes here, where if look at this box carefully you see there are seven dots around the cube, so there are his seven valence electrons.

那么，让我们回到讲义，把它们填进去，七个电子，还有另外一种方法可以知道这些,那就是看看路易斯的讲义这里，大家可以看到这个立方体周围有七个点,因此有七个价电子。
