Nanocrystals, also known as quantum dots, are semiconducting particles with a diameter of a few millionths of a millimeter.(納米晶體，也被稱為量子點(diǎn)，是一種直徑只有百萬(wàn)分之一毫米的半導(dǎo)體粒子。)

This is in vertical position. 149.9 But I would think that the uncertainty of my measurement is probably 1 millimeter.(放置的鋁條，149。,考慮到,測(cè)量的不確定度,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.(平均來(lái)說，這些苔蘚以每年大約1毫米的極慢速度生長(zhǎng)，而某些草皮有數(shù)米厚。)

It's about a millimeter thinner than the iPhone 4, even though it's got most of the same guts.(它雖然和iphone4的內(nèi)部配置相同，但看上去卻少了好幾毫米。)

The other type doesn't use X-rays but instead a technology called millimeter-wave scanning.(另外一種不使用X射線，而是采用了一種叫做毫米波掃描的技術(shù)。)

If the ground stations tracking the satellites are not accurate to the millimeter, then the satellites cannot be accurate either.(如果跟蹤衛(wèi)星的地面站位置不能精確到毫米，那么衛(wèi)星也是不可能精確的。)

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.(在離水不到一毫米的地方，空氣的溫度接近于地表水的溫度，空氣中的水蒸氣幾乎飽和了。)

Researcher said it is the first true millimeter-scale complete computing system.(研發(fā)人員稱這是第一套真正意義上的毫米級(jí)、完整的計(jì)算機(jī)系統(tǒng)。)

The millimeter-wave machine is grayish-white and is more cylindrical.(而毫米波掃描儀則是灰白色的，有些像圓柱形。)

The process is possible only with certain materials (plastics, resins and metals) and with a precision of around a tenth of a millimeter.(這個(gè)過程只能用特定的材料（塑料，樹脂和金屬），精度在0.1毫米左右。)
