diffusion timeの例文

• This function is typically repeated, varying the duration of gas input and diffusion time.
• By contrast, a meter-sized volume of seawater has a magnetic diffusion time measured in milliseconds.
• Consequentially, since diffusion time for the surfactants is large, the Marangoni effect has time to take place.
• Slight changes to the amount of diffusion time, uneven doping levels, etc . can have large effects on device properties.
• The surfactants have a larger diffusion time than the bulk of the solution; therefore, there is a smaller concentration of the surfactants in the indentation.
• In 1980, Pearsall developed a photodiode design that exploits the uniquely short diffusion time of high mobility of electrons in GaInAs, leading to an ultrafast response time.
• However, such enhancement is not observed for small droplets with diameter of nanometer scale, because the wetting time scale is much smaller than the diffusion time scale.
• In practice, the diffusion times need to be sufficiently different a factor of at least 1.6 which means the molecular masses must differ by a factor of 4.
• After a few times the diffusion time scale one would expect the air to have separated to the degree it is able, but it would not be a big effect.
• The diffusion time scale in absolutely still air will be t \ approx { l ^ 2 \ over ( 0.2 cm ^ 2 / s ) }, where l is the characteristic length of the system.
• One can estimate the diffusion time across a solar active region ( from collisional resistivity ) to be hundreds to thousands of years, much longer than the actual lifetime of a sunspot so it would seem reasonable to ignore the resistivity.
• To prevent saturation of the active transistor so that the diffusion time that slows the recovery from saturation will not be involved in the logic delay, the emitter and collector resistances are chosen such that at maximum input voltage some voltage is left across the transistor.
• It is defined by E _ T = \ hbar D / L ^ 2, where D is the diffusion constant and L the size of the system, and thereby inversely proportional to the diffusion time t _ D = L ^ 2 / D through the system.
• According to current models, random scattering from free electrons in the solar radiative zone ( the zone within 75 % of the solar radius, where heat transfer is by radiation ) sets the photon diffusion time scale ( or " photon travel time " ) from the core to the outer edge of the radiative zone at about 170, 000 years.
