The following relationship has been derived between the temperature T and constant heating rate for a constant value of the degree of conversion 1 T = a + b ln 尾 ( a = const., b = const.) The validity of the same relationship for non-classical non-isothermal kinetics is also discussed...
The temperature dependence of the rate constants for the reactions F + CH3F and F + CH2F2 The dependency of the rate constant k τ for the reactions O + + O 2 → O 2 + + O k 1 (1)O + + N 2 → NO + + N k 2 (2) on the gas temperature T, the vibrat... ...
The variables that influence the constant-rate period are the so-called external factors consisting of gas mass velocity, thermodynamic state of the gas, transport properties of the gas, and the state of aggregation of the solid phase changes in gas temperature, humidity, and flow rate will ...
The range and the rate of PAHs disappearance from soils was correlated with their volatilisation ability (characterised by Henry's constant H s ), bioavalibility (characterised by water solubility W s ) and sorption affinity (characterised by three parameters: octanolwater partition coefficient log...
aNewton's law of cooling: If an object is at a temperature T at time t and the surrounding is at a constant temperature Te then the rate of change in T is 牛顿的冷却定律: 如果对象在温度T在时间t,并且围拢在恒温Te然后变化的率在T上的是 [translate] ...
The sintering of alpha-Al_2O_3 powder compacts with the mean particle size of 350 nm has been investigated at constant heating rates of O.5-5 deg C min~(-1). Curves of the instantaneous relative density differences and the temperature for different heating rates were constructed, the ...
Incubation temperature also influences both alevin and fry size. In general, low incubation temperatures produce larger alevins and fry than high incubation temperatures.In addition to data on constant incubation temperatures, the effects of varying temperature regimes on the survival, rate of ...
One reason that thermophilic metabolism may depart from the canonical MTE hypothesis is that they assumed constant biomass with temperature, but microbial biomass in hot springs also decreases exponentially with temperature [20]. For thermophiles, environmental temperature has been a major determinant of ...
28 The rate of diffusion step in the permeation process may also increase with temperature following an Arrhenius equation type of relationship.27–31 Temperature, therefore, exhibits its effect on breakthrough time and permeation rate through the diffusion coefficient (D) and solubility (S). The ...
deion solution was perfused at aconstant flow ratethrough a chamber attached to the skin surface. The chamber was designed so that the electrodes were installed inside at the inlet and outlet, and a 14mm3channel was constructed at the bottom to wash out sweat. The 90%response timewas 0.12s...
