3. A theorem on sufficiency and necessity of fuzzy positive matrix is proposed after much analysis. Based on the thought of minimun deviationan, an optimization model is constructed first, and then a formula with parameter is taken advantage to approximate the corresponding element in the fuzzy co...

(2) Relative atomic mass (r.a.m.)：一个 element 各 isotopes 的relative mass 的 weighted average（加权平均）。例如自然界中含 75% 的 35Cl 和 25% 的 37Cl。加权平均得r.a.m. of Cl = 35.5 (3) Relative molecular mass (r.m.m.)：一个 molecule 的 relative mass。例如 r....
Expressions of shape functions are given for the element. A test problem was solved using the element and the formula, and the results are shown to be more accurate than those obtained when solving the same problem using infinite elements with exponential decay and Gauss-Laguerre numerical ...

Calculation of overhead transmission line impedances a finite element approach In this paper, the finite element method (FEM) is used to calculate the frequency dependent series impedance matrix of an overhead transmission line. A nov... Triantafyllidis, D.G,Papagiannis, G.K - 《IEEE Transac...
Simplest formulas are determined by establishing the mass of each element present in a given mass of the compound. From those masses one finds the number of moles of each element. The mole ratio must be equal to the atom ratio in the compound and from that ratio the simplest (empirical) ...
This example, when added to the concat field, concatenates each element in the dogs field, containing, "Poodles":"Huskies":"Corgis" with each element in the love field, containing: "I love ":"I love ":"I love ": @For(n := 1;n <= @Elements(dogs); n := n+1; ...
Definition of 1) A formula unit in chemistry refers to the simplest ratio of ions represented in an ionic compound. It indicates the number of atoms of each element in a compound, providing a snapshot of the compound's composition. Category/Context...
