5. Methane is a flammable gas on Earth but liquid on Titan because of the moon's intense atmospheric pressure and cold. 6. The fabric was kept inflated by an internal pressure higher than the outside atmospheric pressure. atmospheric pressure 英英释义 ...
Atmospheric pressure is the force per unit area exerted by a body of air above a specified area (called an atmospheric column). It is expressed in several different systems of units, including millimeters (or inches) of mercury, pounds per square inch (p
Core Nutation (FCN) and some forced nutations are evaluated numerically from the global pressure field provided by the European Center for Medium Range Weather Forecast (ECMWF) on the Earth's solid surface using a 12-year long pressure data set sampled every 6 h on a (1.125掳脳1.125掳) ...

3、Then the material in the feeding tank enters the feed hose and the charging cylinder via the tee piece underatmospheric pressure.(供料桶内的物料被大气压力压入出进料软管,通过进出料的三通管进入料缸。) 4、Theatmospheric pressureat the surface is only 1% of that on Earth.(在表面的大气压力...
Pressure caused by the weight of the air. At sea level it has an average value of one atmosphere and gradually decreases as the altitude increases. Did You Know?The atmosphere that blankets the Earth gently presses down on us, and the subtle variations in thisatmospheric pressuregreatly affect...
every air molecule that bumps into any object exerts a force. Atmospheric pressure is simply the sum of those many forces. On average, the atmospheric pressure on Earth, at sea level, is 14.7 pounds per square inch. This means that there is a force of almost fifteen pounds pushing against...
A barometer measures atmospheric pressure. There is a right way and a wrong way to use one, however. (Image credit: Sergey Tarasenko | Shutterstock) Books on meteorology often describe Earth's atmosphere as a huge ocean of air in which we all live. Diagrams depict our home planet as ...
so long as attention was confined to daily mean values of pressure, I have now obtained results pointing to a hitherto unsuspected relation between the type of the diurnal variation of pressure and the general state of magnetic conditions, as regards disturbance and quiet, over the earth. As...
