The computative methods of the relative rotation in the velocity field and the whole rotation of linear structure and the error ellipsoid of the velocity field are also discussed.

A method without any approximation to separate the global rotational degrees of freedom in the Schrdinger equation for an N -body system completely from the internal ones is presented.

The technology of whole turning and raising and the method of monitoring and controlling to some concrete continuous beam bridge with multispan are introduced. According to the practical results, some advices are advanced to the construction and control of similar engineering.

As being superfluid, particle current in BEC is irrotational and this makes that its respondence to rotation is different from rotating as a whole for usual fluid and is to form a vortex or vortex lattice.

The surface reliefs of lath martensites, {225 }f and {259}f martensites are compared based on AFM abservation and measurement (with assistants of SEM and optical microscope) in this paper. As a result, the surface reliefs of lath martensites are found to have an arc appearance , which embodys the rotation of the martensites , the least width and the largest change interval of measured list angles ;

Because they fossilize well, these 'stones' inform us in detail about the geological past; not only about the history of the Earth as a whole (rotation, tectonics, sea-level changes), but also about past local environmental conditions in the sea.

However phosphorus and potassium are required and would normally be applied as maintenance dressings for the benefit of the whole rotation.

There are few data points, but they do not cover the whole rotation length, or the same kind of production systems.

4), suggest that movement detectors looking into opposite directions in the visual field might interact specifically to extract global rotational image flow.

Hence the global rotational correlation time is not very high (τg298=3880±750?ps) compared to the corresponding DTPA-BA-based polymer (about 15 monomeric units), where τg298=6500?ps.

The global rotational correlation times increase with increasing length of the side chain (500-2800?ps for C10-C18).

Vertical distributions of various components of the tropospheric global rotational kinetic energy, enstrophy and available potential energy during July 1979, and the contributions to these from different zonal wave categories were studied.

These expressions include only trigonometric functions and are easily evaluated by hand calculation for estimates of the essential quantities from which we can determine a global rotational motion of the torque-free motion.

In this paper, a general approach to establish differentia 1 equations of the forced vibration for the planar and spatial nonorthogonal bar-chain system under multi-support excitations,which may be arbitrarily irregular at each support and along each direction(x,y, z), is studied, considering the complicated geometrical constraint lelationship of the system,The final result of the study is given in form of forced vibration under the action of multiple equivalent disturbances.In the typical equations, the independent axis rotational displacements of the bar or chain are taken as the generalized coordinate vectors, of which the number of orders is evidently equal to that of degrees of kinematic indeterminacy of the system. The corresponding generalized mass matrix depends on both the mass distribution and the geometrical constraint characteristics of the system. The corresponding generalized stiffness matrix depends on both the stiffness characteristics and the geometrical constraint characteristics of the system.The equivalent disturbance matrix (i. e. the earthquake input) is the resultant of two components. One is inertial input which depends on accelerations on the multiple supports along differnt directions (x, y, z) and the mass distribution of the system. The other is elastic input which depends on the displacements on multiple supports along different directions(x, y, z)and the stiffness characteristics of the system. Furthermore, both components depend on the geometr cal constraint characteristics.The existing 3-dimensional theory of seismic loads and the expression of pseudostatic transmission of the earthquake are special cases for the results given in this paper.

A rigid pier foundation is sufficiently stiff to displace (rotate) under lateral load without causing appreciable distortion from its axis, The lateral displacement at any depth is related to the center of rotation without exception.This condition simplifies the displacement compatibility analysis and has generated a proliferation of "rigid pier" solutions.

A rigid pier foundation is sufficiently stiff to displace (rotate) under lateral load without causing appreciable distortion from its axis, The lateral displacement at any depth is related to the center of rotation without exception.This condition simplifies the displacement compatibility analysis and has generated a proliferation of "rigid pier" solutions. The lateral load-deflection response of a rigid pier sometimes maybe significantly influenced by the friction force at the interface between the pier and soil; this fact, however, is not often considered in most of the published rigid pier solutions. In this paper a better answer is given for the problem, taking into account the effect of the lateralfriction force by the subgrade-reaction approach, in which the pier reaction at any point is described to be directly proportional to the deflection and a power function with the depth at that point.

Many single-story mill buildings were destroyed in Tangshan,Hai-cheng and Xingtai Earthquakes. In these buildings the damage of corner columns and columns remote from the terminal transverse wall are more serious than others. It means that the roof slabs were deformed and rotated in horizontal plane during earthquakes. According to the experimental data and conclusions drawn from the earthquake damage surveys, a spatial structural mechanical model in consideration of lateral stiffness of transverse masonry wall...

Many single-story mill buildings were destroyed in Tangshan,Hai-cheng and Xingtai Earthquakes. In these buildings the damage of corner columns and columns remote from the terminal transverse wall are more serious than others. It means that the roof slabs were deformed and rotated in horizontal plane during earthquakes. According to the experimental data and conclusions drawn from the earthquake damage surveys, a spatial structural mechanical model in consideration of lateral stiffness of transverse masonry wall and its spatial action and rotational effect of roof slab has been established in the paper. The calculating scheme with "series-parallel multiple mass particles system" is adopted in the translation-torque coupling earthquake response analysis for single-story unsymmetrical mill buildings. A practical method according to the earthquake response spectrum is also given. Based on the calculation results of spatial analysis of several hundreds mill buildings, some applicable tables are made and a simplified method for manual calculation is presented in the paper as well.
