particles (assuming their reference system is Ru), as a particle swarm, move in a certain direction with a group speed u (i.e., the norm of the average velocity) relative to R0, their (or the sub-particle swarm's) average speed relative to Ru is slower than that of particles (or ...
The Conservatives plan to adopt this strategy by making utility companies print the average local electricity and gas usage on people's bills. 出自-2015年12月阅读原文 Take your average trade union member, chances are they will be politically motivated and be used to collective action— much like...
of the average flow speed of the gas-solid two-phase flow in an industrial pipeline with the measurement error being 2%.The straight tube section required for installation at the site is short.The meter has a small flow resistance and a long service life,capable of meauring the average flow...
SAT物理题Which of the following statements is true about the ideal gas contained at a fixed volume when its temperature is raised?A.The density of the gas decreases.B.The average velocity of the gas particles increasesC.the density of the gas increases.D.the pressure remains constant.E.the ...

and then the liquid is blown out by another fluid (usually compressed gas) to measure the maximum pore size of the porous materials [10,13].The infused liquid is pushed out to make bubbles when the gas pressure reaches a certain value, and the pressure difference is measured when the first...
The convective component of heat conduction is due to collision of gas molecules residing in the space between soil particles and requires the presence of an atmosphere to operate. Since sensible and latent heat fluxes are several orders of magnitude more effective in transporting energy compared to...

pollution is the gas from cars. Statistics (统计资料) show that 93 percent of all auto trips are within cities. Another major kind of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city ...
The resolution of this conundrum, developed over the past several years, is that the gammas are not emitted immediately; instead the initial energy release of the explosion is stored in the kinetic energy of a shell of particles (including photons as well as electrons and their antimatter counte...
