Rather like blood circulating in our veins, inside the termites nest it is air that is moved by external temperature and pressures.
就像我们血管里的血液流动一样，在蚁穴里的空气也是由外界的气温和压力控制的。
Note: the operations from day 3 to day 12 depend on site crew, re-bar complexity, concrete type, external temperature, etc. and are estimation from past jobs.
注：3-12天的工作进度取决于工人素质、钢筋笼的复杂性、混凝土类型、环境温度等。
Considering the effect on permafrost table, there is a kind of dynamic equivalence to some degree among pavement types, external temperature and embankment heights.
从对基底冻土上限影响的角度来看，路面类型、外部气温与路基高度三者间存在一定的动态等效关系。
The parts have a standard voltage input, which together with the differential reference input allows easy interface to an external temperature sensor, such as an RTD, thermistor, or diode.
两款器件都有一个标准电压输入，当与差分基准电压输入结合使用时，可方便地与一个外部温度传感器(如rtd、热敏电阻或二极管等)接口。
In the mass concrete construction in cement plants, cracks in the concrete may be controlled by reducing the hydration heat and cooling with water to control the internal and external temperature.
在水泥厂工程大体积混凝土施工过程中，可以通过降低水泥水化热和冷却水冷却，控制混凝土内外温差等措施来控制大体积混凝土有害裂纹的产生。
