In gases, conduction occurs by the random motion of molecules, so that heat is “diffused” from hotter regions to colder ones.金属导热源于自由电子的运动,因此导热系数与电导性是一致的。导电性较差的固体和液体,热传导源于相邻分子或原子振动引起的动量传递。气体热传导则源于气体分子的自由运动,即热量从...
The field dependence of the drift velocity is explained qualitatively. The observed maximum in the electron mobility as a function of temperature can be related to correlation effects between the molecules in the liquid.关键词: Experimental/ argon electron mobility organic compounds/ motion of excess ...
The fact is that there are electrons in each atom, and we know from their spectra that there are internal motions; each of the electrons should have at least \frac{1}{2}kT of kinetic energy, and something for the potential energy, so when these are added in, γ gets still smaller. ...
States of Matter:The most commonly known states of matter are solid, liquid, and gas. Two other states have been discovered recently. In a plasma, designated as the fourth state of matter, the electrons are independent of the atomic cores. A fifth state are the Bose-Einstein conden...
motion; in particular electrons should be accom- panied by waves which determine their motion. It would seem at first sight that this would involve a contradiction with what is already known about the motion of electrons. For example, waves spread after passing through a small aperture, while...
same laser field then accelerates ions and free electrons toward the electrodes. The current depends on the laser field, e.g., for a certain CEP more electrons impinge on the left detector than on the right (as shown in Fig.1b) or vice versa when introducing a shift ofπin CEP. The ...
Further promotion of the catalytic site activity has been reported in the heterogeneous Fenton literature by adding electron-rich materials to the catalyst, such as carboxylate ligands (Hou et al., 2016; Huang et al., 2017; Wang et al., 2011; Zhang et al., 2014), combining with carbon ...
1.(General Physics) the study of the behaviour of conducting fluids, such as liquid metals or plasmas, in magnetic fields 2.(General Physics) the generation of electricity by subjecting a plasma to a magnetic field and collecting the deflected free electrons ...
“photocurrents” generate ultrabroadband terahertz radiations which find direct applications in the coherent spectroscopy of macromolecules. At relativistic intensities, gas plasmas develop nonlinear electrostatic fields used in laser-wakefield particle acceleration. Accelerated electrons crossing the plasma-vacuum...
