  uniform rotation
The fluid flow between a pair of coaxial circular cylinders generated by the uniform rotation of the inner cylinder and an azimuthal pressure gradient is susceptible to both Taylor and Dean type instabilities.
      
However, the system is stable in the potentially stable case and unstable in the potentially unstable case for highly viscous fluids in the presence of a uniform rotation.
      
The effects of a variable horizontal magnetic field and a uniform rotation are also considered.
      
The boundary layer at the surface of an elliptic cylinder is considered, when the cylinder is set into uniform rotation about an axis through its centre, in a fluid that is otherwise at rest.
      
If the isotherms are perpendicular to the magnetic field, non-uniform rotation about the pipe axis occurs near the ends.

In this paper the macroscopic anisotropy in RKKY + DM spin glasses is investigated. The configuration of intermediate equilibrium is observed and the anisotropy constants are obtained by calculating the energy increment of the system due to uniform rotation. It is shown that the anisotropy in RKKY + DM spin glass is unidirectional and the constants are independent of the axes while proportional to the concentration of impurities. When an external magnetic field is applied, the distribution of rotation...

In this paper the macroscopic anisotropy in RKKY + DM spin glasses is investigated. The configuration of intermediate equilibrium is observed and the anisotropy constants are obtained by calculating the energy increment of the system due to uniform rotation. It is shown that the anisotropy in RKKY + DM spin glass is unidirectional and the constants are independent of the axes while proportional to the concentration of impurities. When an external magnetic field is applied, the distribution of rotation angles and of axes of spin clusters can be found, indicating that the system is undergoing a quasi-rigid rotation. Theoretical findings prove to be in agreement with recent tests on torque.

Traverse motion of the thread guide combined with uniform rotation of the bobbin is necessary to form a cylindrical package of yarn or thread material. The fluctuation of linear density (i.e., mass per unit length) of the wound thread as caused by the continuous changing of the thread guide position during its traverse motion is reflected directly in the variation of yarn tension or stress during the winding process, which is an important factor affecting the winding performance and the quality of the...

Traverse motion of the thread guide combined with uniform rotation of the bobbin is necessary to form a cylindrical package of yarn or thread material. The fluctuation of linear density (i.e., mass per unit length) of the wound thread as caused by the continuous changing of the thread guide position during its traverse motion is reflected directly in the variation of yarn tension or stress during the winding process, which is an important factor affecting the winding performance and the quality of the products. A theoretical analysis is therefore made, on a quantitative basis, of the general relationships between all the main relevant winding parameters and the resulting yarn unevenness. Also, some representative numerical results have been presented here for the reference of engineering design practice.

纱线依靠导纱器的往复运动和卷装本身的回转运动而绕成筒子.由于导纱器的位置往复变动,将使纱线的线密度(单位长度的质量)发生涨落变化.这种涨落实际上又反映了卷绕过程中纱线截面上应力(或应变)的起伏,从而将使卷绕效果和成品质量受到相应的影响.本文从理论上定量地分析了各主要运动学参数同不匀度之间的关系,并给出了几组代表性的数值解,可供工程实践参考.

In this paper, the differential equations of motion will be established for variable-mass holonomic mechanical systems constrained to the uniform rotation, including the equations in Lagrange form, Nielsen form and Appell form. The application of these new equations is illustrated with an example.
