Viscosities and molar volumes of binary solutions,viz., Toluene-Nitrobenzene, Toluene-Bromobenzene, Toluene-Cyclohexanone, Cyclohexane-Cyclohexanone, Cyclohexane-Nitrobenzene, Cyclohexane-Acetic acid, Cyclohexane-Propionic acid and Cyclohexane-Butyric acid have been measured. The experimental results have been discussed in terms of viscosity-composition relations developed for binary solutions by Grunberg and Nissan and Katti and Chaudhri. 相似文献

Exchange of intensities among various spectra of Mn2+ in NaCl single crystal, corresponding to Mn+2 ion associated with various point defects, is described as a function of temperature and time. The variation of line width with temperature is discussed. The fine structure parameter D for a particular spectrum is measured with temperature and is shown to behave like D=D0 (1+bT+cT2). Thermal formation of new complexes and their lifetimes are discussed. A new short-lived complex is found and a model for the same is suggested. 相似文献

A portable bifurcation and stability analysis package, called BISTAB, is described. The package is written in FORTRAN V and can follow the connected set of equilibrium curves for a system of nonlinear ordinary differential equations in the state × parameter space by varying a bifurcation parameter. The curves are traced from an initial point with the continuation method of Kubicek, and the tangent method of Keller is used to find initial points on bifurcating curves near simple bifurcation points. Linearized stability analysis, location of Hopf bifurcation points, and sorting of points for plotting are also supported. While the package contains no new numerical methods, the lack of a requirement for any derivative information higher than the Jacobian makes BISTAB computationally efficient and useful for applied problems where nonnumerical bifurcation analysis may be difficult. 相似文献

We explicitly compute, following the method of Weyl, the commutator [Q, P] of the position operatorQ and the momentum operatorP of a particle when the dimension of the space on which they act is finite with a discrete spectrum; and we show that in the limit of a continuous spectrum with the dimension going to infinity this reduces to the usual relation of Heisenberg. 相似文献

We present an approach to providing broad-based accessibility to graphical applications by employing the capabilities of the
Eclipse platform and aspect-oriented programming (AOP) in a way that leverages the strengths of each. We first describe the
Eclipse platform and the variety of frameworks that can be useful to the effort. We also present the advantages of aspect-oriented
programming and contrast aspect-oriented programming with object-oriented programming (OOP). Then, we discuss how to use the
Eclipse frameworks and AOP in the design of accessible Eclipse-based applications and share some situations of when to leverage
these frameworks and when we do not from the perspective of robustness and efficiency. 相似文献
