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。)
This is in vertical position. 149.9 But I would think that the uncertainty of my measurement is probably 1 millimeter.(放置的铝条，149。,考虑到,测量的不确定度,它大概是1毫米。)
On average these mosses grow at the glacial speed of 1 millimeter per year-and some of the turfs are meters thick.(平均来说，这些苔藓以每年大约1毫米的极慢速度生长，而某些草皮有数米厚。)
It's about a millimeter thinner than the iPhone 4, even though it's got most of the same guts.(它虽然和iphone4的内部配置相同，但看上去却少了好几毫米。)
The other type doesn't use X-rays but instead a technology called millimeter-wave scanning.(另外一种不使用X射线，而是采用了一种叫做毫米波扫描的技术。)
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。)
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。)
Researcher said it is the first true millimeter-scale complete computing system.(研发人员称这是第一套真正意义上的毫米级、完整的计算机系统。)
The millimeter-wave machine is grayish-white and is more cylindrical.(而毫米波扫描仪则是灰白色的，有些像圆柱形。)
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。)
