The time evolution of C(t) is a monotonous descending process, while the whole C(t) versus t curve falls down with noises intensity reducing and the cross correlation between real and imaginary parts of the quantum noise weakening, which shows that the great influence of the noises intensity and the cross correlation between real and imaginary parts of the quantum noise on the time evolution of C(t).

The nonlinear optical properties of the films were determined by a single beam Z-scan. The values of the real and imaginary parts of the third-order nonlinear susceptibility X(3) were measured to be 3. 78 × 10-9esu and 1. 02×10-9esu.

The open-aperture and closed-aperture results show that SBN thin films exhibit a nonlinear optical response with the real and imaginary parts of the third-order nonlinear optical susceptibility being 4.139×10-7 esu and 1.104×10-7 esu, respectively.

Using the characteristic that the real and imaginary part of each harmonic copmonent of torsional vibration in transient operation is equal to the linear superposition of the real and imaginary parts of each harmonic component in steady condition and trend term,the accuracy amplitude of each harmonic component for steady condition can be received by eliminating the trend term.

The real and imaginary parts of the permittivity of water clusters with absorbed O2 molecules are aperiodic functions of frequency.

Both the real and imaginary parts of dielectric permittivity are substantially increased at frequencies corresponding to intramolecular vibrations of atoms when each cluster of aqueous system adsorbs one argon atom.

In this frequency range, both real and imaginary parts of dielectric permittivity decrease monotonically after the absorption of C2H6 molecules by an aqueous ultradispersed system.

The dispersion analysis of the frequencies of the real and imaginary parts of the complex impedance made it possible to reveal a unified equivalent electric circuit for these cells and to calculate its parameters.

The rms errors in measuring the real and imaginary parts of the complex permittivity, which varied over the ranges 4.79-11.03 and 0.39-3.15, were 0.21 and 0.03, respectively.

The pressure distribution of noncavitating potcnial flow around gate piers shown in Fig. la has been analysed. The analysis has its practical significance in that the minimum-pressure coefficient is closely related to the incipient cavitation number. After the W plane was mapped on to, the t plane with known transformations except an unknown parameter m, the complex velocity was expressed by Eq. (10) in terms of an unknown function Ω (t). Eqs. (13) and (16) indicate that along the boundary f and g are respectively...

The pressure distribution of noncavitating potcnial flow around gate piers shown in Fig. la has been analysed. The analysis has its practical significance in that the minimum-pressure coefficient is closely related to the incipient cavitation number. After the W plane was mapped on to, the t plane with known transformations except an unknown parameter m, the complex velocity was expressed by Eq. (10) in terms of an unknown function Ω (t). Eqs. (13) and (16) indicate that along the boundary f and g are respectively related, to the magnitude of the boundary velocity and the boundary geometry. Three equations to solve for the three unknowns are furnished by the conditions along the boundary: (1) The angle τ is given as a function of z. (2) f and g, being the real and imaginary parts of an analytic function, are related to each other. (3) The points of tangency are transformed to points on the real axis of the t plane. For the case in which the nose curve is composed of circular arcs, Eqs. (22), (28) and (29) were derived. The functions f and g were found numerically by iteration, and m was computed from Eq. (28). The distribution of velocity and that of pressure along the line of symmetry and the boundary were computed and plotted in Fig. 5, in which the pressure distribution from wind tunnel tests was also included. Preliminary results on incipient cavitation number were plotted in Fig. 6, to be compared with the theoretical |C_(pm)| curve. More tests are being done to study the scale effects.

The basic idea is as follows: By aid of Zangwill penalty method, the optimal load flow problem is transformed from a constrained optimization problem into a sequential unconstrained optimization problems which are solved by the BFS (Broyden-Fletcher-Shanno) method. The BFS method possesses better numerical stability so that the high precision of uni-dimensional...

The paper proposes a model for optimal load flow calculation in which the real and imaginary parts of all the node voltages are used as state variables. The basic idea is as follows: By aid of Zangwill penalty method, the optimal load flow problem is transformed from a constrained optimization problem into a sequential unconstrained optimization problems which are solved by the BFS (Broyden-Fletcher-Shanno) method. The BFS method possesses better numerical stability so that the high precision of uni-dimensional search is unnecessary. Therefore, the guadratic interpolation that needs smaller amount of calculation can be used as uni-dimensional search technique. Thus the amount of calculation of the method is decreased,and the convergence can be quaranteed sufficiently. Finally the effectiveness of the method is proved by the given examples.
