1·These sections of rocks are dissected, using a laser, into slices a millimeter or less thick.

采用激光将这些小岩石块切分成一毫米或更薄的薄片。

2·It can make fine visual distinctions because it is blessed with one million cones per square millimeter in its retina.

它的视网膜上每平方毫米有一百万个视锥细胞，所以它能分辨出很细微的视觉差别。

3·Nanocrystals, also known as quantum dots, are semiconducting particles with a diameter of a few millionths of a millimeter.

纳米晶体，也被称为量子点，是一种直径只有百万分之一毫米的半导体粒子。

4·If the ground stations tracking the satellites are not accurate to the millimeter, then the satellites cannot be accurate either.

如果跟踪卫星的地面站位置不能精确到毫米，那么卫星也是不可能精确的。

5·They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment.

他们已经制造出能够在受控的工厂环境中识别出几分之一毫米误差的机器人。

6·The process is possible only with certain materials (plastics, resins and metals) and with a precision of around a tenth of a millimeter.

这个过程只能用特定的材料（塑料，树脂和金属），精度在0.1毫米左右。

7·Within about a millimeter of the water, air temperature is close to that of the surface water, and the air is nearly saturated with water vapor.

在离水不到一毫米的地方，空气的温度接近于地表水的温度，空气中的水蒸气几乎饱和了。

8·There might be a couple hundred of these color sacks per square millimeter of the octopus' skin, and depending on the species, they can come in as many as five different colors.

章鱼每平方毫米的皮肤上可能有几百个这样的色袋，根据章鱼品种的不同，色袋可以有多达五种不同的颜色。

9·However, the product has changed dramatically, from a single thickness of 6.8 mm to a range from sub-millimeter to 25 mm.

然而，玻璃制品在厚度上发生了巨大变化：从单一的6.8毫米变为亚毫米级至25毫米区间的任意厚度。

10·These seeds are actually chondrules: millimeter-sized melted droplets of silicate material that were cooled into spheres of glass and crystal.

这些种子实际上是陨石球粒：冷却后变成玻璃球和水晶球的毫米级熔融状硅酸盐小液滴。
