多次揭示一阶系统的运行规律，其中τ(tao)就是时间常数time constant。
The mechanism, which dominates the heat transfer in the system, is found from the plot of the temperature dependence for the time constant. The heat loss to the surrounding gas and the thermal contact between sensor and crucible through the gas layer between are the main reasons for the ...

Assuming the thermal properties are constant, temperature response can be calculated for the insulated steel member subjected to a time-varying boundary condition (e.g. fire condition), using the principle of superposition (Duhamel's theorem, [11]), asTs(t)=T0+∫0tθg(t-ξ)d(1-θs(ξ)...
The new method is compared with the classic Beck''s function specification method, i.e., with a constant number of future temperatures. Using a clear definition of the different errors, the comparison shows that, in many cases, the modified method significantly improves the IHCP resolution.doi:...
engineering interest reduce to this classic case. As we heat the material from the left surface, the entire volume of material gets gradually, but nonuniformly, hotter. There is also radiative cooling and some free convection from the left side, approximated as a constant heat transfer ...
Analysis of a simple circuit for constant temperature anemometry Perturbation equations describing the response of hot wires and hot films operating in a simple constant-temperature circuit are developed. The heat transf... PD Weidman,FK Browand - 《Journal of Physics E Scientific Instruments》 被引...
So, two piecewise dynamic equivalents (constant current load equivalent and constant transfer admittance) are introduced to eliminate the algebraic equations. The proposed method is about 4–6 times faster than the full Jacobian technique. The stability evaluation time is about 0.5 s, which can be ...
[10] assumed that a real collision takes place in every fictitious collision predicted by the modified spring constant and simulated metallic solid sintering in fluidized bed. A similar approach can be adopted to deal with particle-to-particle heat transfer and/or van der Waals interactions. View...
