a上周操场上有两棵树,现在只有一棵了。下周操场上会有五棵树。 Last week in the drill ground had two trees, now only then.Next week in the drill ground can have five trees.[translate] afrida frida[translate] aGiven an equilibrium point 给出平衡点[translate]...
aThe stability boundary of stable equilibrium point is given by the union of unstable manifold of the controlling equilibrium points on its stability boundary. 稳定的平衡点稳定界限由控制平衡点的不稳定的多头管联合在它的稳定界限给。[translate]
6 A differential equation is given by(dx)/(dt)=(k-R)x-5x^3 .dt where R and S are positive constants and k is a parameter.(i) If k R, show that there is only one equilibrium point and comment on its stability.[4](ii) If k R, find all the equilibrium points and comment ...
This result can explain the nonzero thermal expansion coefficient of solids. As τ increases, the equilibrium point shifts(see also the discussion in Kittel,Introduction to Solid State Physics, p.142, where(14)is obtained by a different method).反馈...
a conical surface that has any given vertex, and is described by a straight line which moves in such manner that the moment of inertia of the given rigid body about the line is in all its positions the same. See also:Equimomental ...
aGiven the nature of the problem and the quantum of data, we first study the data properties from an econometric perspective and find that co-integration and error correction models are required to establish the equilibrium relationship between the markets. 假使问题和量子的本质数据,我们首先学习数据...

Under suitable assumptions on ...
As in quantum mechanics, the eigenstates can be the starting point for many analytical and semi-analytical studies. One common technique is perturbation theory, applied to small deviations from an ideal system – closely related to the variational eqn [3], perturbation theory can be exploited to...
Assume that ξ is a Lebesgue point of μ and that μ′ is positive and continuous at ξ. Let { A n } be a sequence of positive numbers with limit ∞. We show that one can choose ξ n ∈ [ ξ A n n , ξ + A n n ] such that lim n →∞ K n ( ξ n , ξ n + a ...
