Axisymmetric elasticity problem of cubic quasicrystal is reduced to a solution of a partial differential equation with higher-order by introducing displacement function.
The large deflection problem of cantilever beams was studied by means of the biparametric perturbation method and the first order derivative substitution from pseudolinear analysis approach.
The condensability of liquid,the Westphal's effect and the continuous flow condition are not only comprehensively considered,but also the dynamic property of the ball valve being established.
A relatively direct method is expounded in this paper to prove the termwise differentiation of power series, and a simple method is expressed to calculate the Fourier coefficient.
The formula of the curve tangent slope at some peculiar point in the orthograph on the stereoscopic surface intersecting line and the method of making tangent are given as well.
We recorded the changes of the heart rate the blood pressure, and the left ventricle pressure, and observed Ginkgetin effect on reducing the myocardial infarct death rate of AMI - reperfused rabbits.
Further, one might suppose that the substance which according to them underlies as matter is too mathematical, and is a predicate and differentia of the substance, ie.
However, the settlement curves of these two typical continuous beam models (Timoshenko and Euler-Bernoulli) are smooth and differentiable, failing to describe the discontinuous features of shield tunnel settlement.
Takes a while to derive. In Math, this word means to obtain something from something else, to get a function or equation from another sequence, for example, by differentiation.
An ordinary differential equation for the longitudinal deformation of an existing tunnel subjected to ground surcharge was established, and the analytical solution of the longitudinal deformation was obtained.
