A general equation for the determination of La using any laser energy in the visible range is obtained. Moreover, it is shown that ID/IG is inversely proportional to the fourth power of the laser energy used in the experiment. 展开
By plotting the capacitive current at 0.05 V versus RHE against the scan rates, the Cdl was obtained as half of the corresponding slope, and the ECSA was derived from the equation ECSA = Cdl/Cs, where Cs is the specific capacitance. The Cs for a flat surface was in the range ...
aDuring combustion, a good pressure fit is one of the most important parts of the analysis because it, and its first derivative are the primary in put to the nonlinear differential equation solution, Eq. (6).points 在燃烧期间,好压力适合是其中一个分析的重要部分,因为它和它的最初倒数是主要的...

Every solution of a linear elliptic equation on a bounded domain may be considered as an equilibrium of a free boundary problem. The free boundary problem consists of the corresponding parabolic equation on a variable unknown domain with free boundary conditions prescribing both Dirichlet and Neumann ...

equation. This paper aims to employ efficient and reliable approximate analytical methods to derive semi-analytical expressions for species concentrations and the effectiveness factor for the underlying kinetic model. The accuracy of the derived approximate analytical expressions of the concentrations is ...
In gyrokinetics, each plasma speciessis described by a distribution functionFs(X, v∥, μ, t) whose dynamics is governed by the following equation: $$\frac{\partial {F}_{s}}{\partial t}+\dot{{{\bf{X}}}\cdot \nabla {F}_{s}+{\dot{v}}_{\parallel }\frac{\partial {F}...
equation ECSA = Cdl/Cs, whereCsis the specific capacitance. TheCsfor a flat surface was in the range of 20–60 µF/cm2, and a value of 40 µF/cm2was adopted here to roughly calculate the ECSA. The stability was measured at a current density of 10 mA/cm2for 12 h...
We then used bivariate analysis and structural equation modeling (SEM)29 to assess fertilizer impacts, and disentangle the relative contributions of diversity and asynchrony to stability (Fig. 1e). Results and discussion Fertilization effects on diversity, asynchrony, and stability Analyses of variance ...
