11. The measurements were correlated with the Tait-type equation for density and the Hard-sphere scheme for viscosity. 利用得到的实验数据,分别拟合了碳酸二乙酯黏度和密度方程。 12. Introducing mass density allows the equation to be simp... ...
The expression for qz contains the mass/charge ratio for a given ion, the size of the ion trap, r0, the amplitude V of the RF potential and the radial frequency Ω, that is, all of the parameters that are needed to understand the operations of the ion trap. View chapterExplore book ...
For mass balance calculations an equation of state (EOS) is required to calculate the density of the gases (CO2, CH4) at certain pressures and temperatures. There are numerous different EOS available, however the most commonly used ones are Span and Wagner (1996) and Setzmann and Wagner (19...

Through constructing a system of three first-order ordinary differential equations, the most important indexes for describing aerosol dynamics, including particle number density, particle mass and geometric standard deviation, are easily obtained. This approach has no prior requirement for particle size ...
A Criterion for Non-Darcy Flow in Porous Media Two types of criteria, the Reynolds number and the Forchheimer number, have been used in the past for identifying the beginning of non-Darcy flow. ... Z Zeng,REID GRIGG - 《Transport in Porous Media》 被引量: 346发表: 2006年 Numerical ...
An evolution equation for f2 involve f3, the joint distribution of three particles and so on up to arrive to the total particle number N. Here the Boltzmann main assumption enters, namely that two given particles are uncorrelated if the gas is rarefied: (3.10)f2(x,υ,x2,υ2)=f(x,υ)...
The Penman–Monteith equation provides the guiding theory for examining how changes in surface properties of vegetation and ecosystems will alter latent heat exchange, the energy used to evaporate water (Monteith 1981). From: Climate Vulnerability, 2013 ...
If a finite elements method is employed for the space discretization, also a mass matrix M has to be taken into account and the matrix equation we have to deal with has the form (2.4) See, e.g., [32]. The generalized Sylvester equation (2.4) can be easily treated as a standard Sy...
