Express in self representation about the orbit angular momentum Operator,eigenvector of p electron in hydrogen atom and transformation each other about mechanics quantity representation have been discussed with the theory of representation. We have got succinct practical express form.
This article dicusses whether single mechanical quantity has certain value in eigen state and uneigen state and discusses the conditions for several mechanical quantities to have certain values simultaneously in the quantum mechanics
In this paper, the author selected the corresponding cells according to the microstructures performance of the materials AM60 to set up the mechanics analysis models and practical effective methods which is across micro/meso/macroscopic scales so that carry out the quantitative transform of stress, strain and other mechanics parameter across different scales.
The results show that if the contact displacement is a constant in the contact zone, the vertical contact stress has order -1/2 singularity on the edge of contact zone, which provides the important mechanics parameter for contact deformation of the quasicrystal.
The results show that if the contact displacement is a constant in the contact zone, the vertical contact stress has order 1/2 singularity in the edge of the contact zone, which provide the important mechanics parameter for contact deformation of quasicrystalline material.
An alternative model is proposed where a mechanical quantity was defined, able to describe the blood damage sustained by red cells under unsteady stress conditions, taking into account the load history.
Geodesic motion in infinite spaces of constant negative curvature provides for the first time an example where a basically quantum mechanical quantity, a ground-state energy, is derived from Newtonian mechanics in a rigorous, nonsemiclassical way.
An observable mechanical quantity is represented by a Hermitian operator whose eigenvalues are real.
The operator of a mechanical quantity is a linear operator in this space.
We distinguish the latter mechanical quantity from the thermodynamic work of adhesion, and we describe explicitly how both may be calculated.
Errors in determining the therapeutically effective force system may result from the electrical measurement of the mechanical quantities by the sensor system and from the fixing of the archwire in therapeutic position.
The application of this method is usually justified by resorting to the energy conservation principle, written in terms both of electrical and of mechanical quantities.
The perturbation parameters chosen here are obtained from solving the equations and are not certain mechanical quantities given precedently.
The protonation of azanaphthalenes and azabenzenes has been studied theoretically using CNDO/2 wavefunctions and perturbation theory in order to examine the correlation between pKa values and quantum-mechanical quantities.[/p]
A particular application of the theory to the Feyman path integrals defined in previous work by the authors yields asymptotic expansions to all orders of quantum mechanical quantities in powers of Planck's constant.
