The rotational effect of the shield lining joint and the setting processof grouting material at shield tail point from liquid state to solid state are taken into consideration in the finite element analy-ses. The mechanical behavior of the segment lining is simulated by use of the author's beam-joint model and the equivalentmethod of variable stiffness of grouting material related with each construction stage.

For further study in dynamic behavior of visco-elastic structures the characters of free vibration for a Burgers visco-elastic beam with rotating effect are also discussed.

As an example, a practical drilling case is analyzed, indicating that the rotating effect has significant influence on the buckling behavior of the drillstring.

A fast reliable theoretical method was sought to predict the performance of the variable-pitch turbines for renewable tidal-current energy conversion. Four streamtube models(single-disk single-streamtube SDST, double-disk single-streamtube DDST, single-disk multi-streamtube SDMT and double-disk multi-streamtube DDMT)based on the momentum theory with the modification of the blade rotating effect were described and compared.

The results show that the poloidal component is generated not only by gravitational force, thermal force and coriolis force as well as stress, but also by the purely mantle's free thermal movement, the toroidal field is only related to the rotation domino effect of earth and the rotation shear movement between the various blocks of lithosphere.

A unified theoretical treatment of the Born-Lertes rotational effect is presented for the special case of a system of two concentric cylinders.

The turbulence in the liquids created by the rotational effect on the dielectric molecules by the electric field may also be a factor in further enhancing the mass transfer rates from the samples.

An analytic model of the rotational effect thermal actuator was established in order to show the periodicity of the capacitance when the angle increases.

Porosity reduces the effect of both, the rotation and the magnetic field, whereas the concentration of the suspended particles reduces the rotational effect.

Taking the microparticle rotation effect into account leads to bimodal wave vibrations, and under conditions of long-short-wave resonance the nonlinear generation of high ultrasonic frequencies by seismic waves is possible.

This paper is concerned with the preparation and characterization of cerium-substituted yttrium iron garnets, which are known to be oxides having a large Faraday rotation effect.

The results indicate that the rotating effect leads to stabilize the basic flows and the horizontal shear effect leads to destabilize the basic flows.

The aim of this paper is to discuss the temperature distribution insidethe event horizon by applying the internal properties of the T--S metrics.We obtain the following conclusions: 1. In the case of T--S metric for odd distortion parameter δ, thereexists a gradient of temperature on a surface of x=const inside the eventhorizon. The temperature on the poles is higher than that on the equator andthe temperature difference is proportional to the rotating rate. But thedirection of the gradient of temperature inside...

The aim of this paper is to discuss the temperature distribution insidethe event horizon by applying the internal properties of the T--S metrics.We obtain the following conclusions: 1. In the case of T--S metric for odd distortion parameter δ, thereexists a gradient of temperature on a surface of x=const inside the eventhorizon. The temperature on the poles is higher than that on the equator andthe temperature difference is proportional to the rotating rate. But thedirection of the gradient of temperature inside the event horizon is justopposite to that of on the surface of a pulsar as we have already pointedout in a preceding paper. 2. We find that the temperature is an imaginary number inside theevent horizon for even δ , It is remarkable that the region inside the eventhorizon is the forbidden region for even δ. So, the imaginary temperatureis corresponding to the forbidden region of motion for the photon. Thisproblem will be investigated later. If all singularities in space--time are hidden behined the non--singularevent horizon in the course of collapse, the space--time may always berepresented by the Kerr metric, i. e., the T--S metric for δ=1, followingthe Israel--Carter theorem. However, the T--S metrics do have ring sing-ularities on the equatorial plane outside the non--singular event horizons.Therefore, the existence of the T--S metrics for δ≥2 dose not contradictthe Israel--Carter theorem because one of the premises of this theorem isnot satisfied in the T--S metrics, that is to say the imaginary temperatureinside the event horizon for even δ is possible of realization.

In addition to pboto-elastic effect, we have also considered rotation and electro-optic effects in calculating Brillouin tensors of LiNbO3 crystals. After careful design and adjustment of the experiment system. Brillouin spectra of LiNbO3 crystals were measured in the 90° scattering scheme. We measured all independent elastic and piezoelectric constants of LiNbO3 crystals made in China in the hypersonic region. The spatial were also measured in the 180?back scattering scheme. Experimental results are in good...

The derivation of the acoustic wave equation which is valid for piezoelectric semiconductor crystals of any symmetry and for any acoustic propagating direction is presented. Three mechanisms contributing to Brillouin scattering in high resistivity ZnO crystal are analysed. They are the elasto-optic effect, rotational contribution of shear wave and the electro-optic effect induced by the aocompaning potential. Thermal Brillouin scattering in ZnO crystal is performed. All of five independent elastic constants of ZnO crystal in high frequency range at room temperature are measured and the values are smaller than those reported in lower frequency by about 4.5%. Four photoelastio coefficient relations are given and the curve of the reciprocal velocity of quasi-longitudinal acoustic wave in x-z plane 10 depicted.
