3) linear ordinary differential equation with constant coefficients 常系数线性常微分方程 1. To find a particular solution of a linear ordinary differential equation with constant coefficients,in which,the nonhomogeneous part f(x) is a polynormial;an exponential function;a sine or cosine function ...
number of grid points. The Euclidean distance can then be recovered from the wave function. Since the wave function is computed for a small but non-zeroh, the obtained Euclidean distance function is an approximation. We derive analytic bounds for the error of the approximation and experimentally ...

Replacing ṽ′(x0,τ) by J̇(x0,τ) because of (9) we can write the last equation as ∂τln(ñJ)=0 and get for the Lagrangian density by integration (13)ñ(x0,τ)=n0(x0)J(x0,τ), where n0(x0) is a constant with respect to τ, representing the initial dens...
A polynomial equation is defined as an equation that can be expressed as a sum of terms, where each term is a constant multiplied by a variable raised to a non-negative integer power. The roots of a polynomial equation can be real and distinct, real and repeated, complex conjugates, or ...

It is important to be aware that an assumption of the steady-state heat transfer cannot be used for modeling thermal processes of induction hardening because, according to the steady-state approach, the temperature would remain constant at a given point of heated component, for all time. However...
