The force acting on the inner cylinder by the viscoelastic fluid while the innercylinder moving axially at a uniform velocity in the eccentric annulus is carried out inthe paper. As to second-order fluid, the numerical results show that T_x makes the innercylinder eccentric while the cylinder stays stable, where T_x is the resultant force actingon the inner cylinder in x -direction; and maks the inner cylinder concentric if thepressure gradient is small while the cylinder is exerted a upward or downward velocity, and vice versa; and the effects will be even obvious if the eccentricity being increased; but as to power-law fluid T_x will be zero.
数值计算结果表明，对于变系数二阶流体在内管做轴向匀速运动的偏心环空中的定常流动，当环空内管静止时，内管所受x方向合力T_x使内管产生偏心效应；而当内管匀速向上或向下运动时，T_x在较小的压力梯度下使内管产生居中效应，在较大的压力梯度下使其产生偏心效应；且随着偏心度的增大，T_x使内管居中或偏心的效应也更加明显；而对于幂律流体，T_x却为零。

而生命美学之所以一再强调，对于超越必然的自由即自由的主观性、超越性的考察，也正是因为它是美学之为美学所必须面对的当代问题，也正是生命美学得以诞生的
This week, the upward revisions have continued on hopes the government's auto stimulus program would propel consumer spending in coming months and force auto makers to make more new cars than previously planned.

The results are as follows:(1) With the imposing of orthopedic force of simulating maxillary protraction on maxilla, in the sagittal direction, the maxillary complex of the SD Rats in experimental group grows more quickly than that in two control groups, and the extent of the maxillary complex increases more evidently. The maxillary complex displays anti-clockwise forward and upward rotation.(2) With the imposing of orthopedic force on maxilla, upper incisors exhibit labial-inclined, labioclination of lower incisors changes insignificantly, and the shape and the dimension of skull are not affected significantly.(3) The expression of TGF-3, in frontomaxillary sutures and palatomaxillary sutures shows different intensity in different extent of time. But The expression of TGF-{3, in experimental group is more intensive than that in two control groups, and that in operated control group and natural growth group has no significant difference.

如果你的能量场内没有红色存在，就会没有足够的生命力量来产生持续提升，因为为了给持续增加振动的向上动力加燃料，提升需要越来越多的生命力量存在。
However, few articles had discussed these differences. We recruited 15 young adults and 13 elderly to join our study. Subjects walked upward and downward in slopes with four different inclinations (0, 5, 10, 15).The vicon 612 motion analysis system was used to collect kinematic data, two AMTI force plates were used to collect kinetic data. A lower extremity model was developed to calculate three dimensional joint angles and moments.
