For the transition induced by the asymmetric perturbations is double - direction , the particle number in the core state is always less half of the total particle number . so , from the point of view of average over time , it is a coexisting state of rotating and without rotating that is formed . this state which is in the josephson tunneling regime of the macroscopic quantum tunneling is a quantum self - trapping state 由于不对称的微扰引起的跃迁是双向的，使得核心态上的粒子数总是少于总粒子数的一半，因此从时间平均的角度看，形成的是旋转的和不旋转的态共存的状态，而且处于宏观量子隧穿的约瑟夫森隧穿区域中，是量子自束缚状态。
It is time for us all to take much greater care when commenting on the cpi figures . many commentators missed the timing of the beginning of the end of deflation - on average by seven or eight months . so let s not be too hasty in predicting the return of inflation , particularly when this can be self - fulfilling , in view of the effects of the sensational headlines on inflation expectation , the lack of objective analysis notwithstanding 既然许多评论员都未能及时指出通缩开始消失的时间平均迟了7至8个月，大家也不用急于预测通胀重临的日子，尤其在没有客观分析支持下，对通胀的预期采用这么煽情的字眼可能会产生很大的影响，以致通胀真的重临。
A two - cylinder model for saal incorporating bem simulations is proposed , which introduces a factor concerning the geometric parameters of the levitator into the expressions for the time - averaged potential u , acoustic radiation force f , and restoring force constant ki , respectively , and builds up the relationship between the levitation capabilities and the geometric parameters of a single - axis acoustic levitator 建立了单轴式声悬浮的优化设计理论模型，采用边界元方法求解入射声场，在表征声悬浮性能的时间平均势u 、声辐射力f _ i和回复力常数_ i的表达式中分别引入了一个涉及悬浮器几何参数的因子。
On the other hand , it is indicated that the velocity field consists of a depth - independent inertial oscillation and a time - mean shear flow , which can be obtained by subtracting the inertial oscillations time mean in one inertial period . the hodograph of the velocity vector of time - mean flow at the different depths consists of a ekman spiral , and the surface velocity is 30 . 3 ? to the right of the wind 一维模式的流场结果表明，混合层中的流场是由惯性波动与时间平均流两部分叠加而成，且通过时间平均消去惯性波动后得到平均流，其不同深度的流速矢量构成一ekman螺旋，表层流速矢量相对风向右偏了30 . 3 ’ 。
Individual experience estimated an ordinary internet bar computer every day might receive the quantity equally to be near about 4 people , each person ' s surfer time average about 2 , 3 hours , the mean or will have no intention 23 click screen goal place to have the possibility very much , in addition will face the tabletop ( computer ) the tendency and will have the contact duration , the attention to be possible to digest to a certain extent in the cerebrum 个人经验来估计一个普通网吧一台电脑平均每天可以接待量将近4人上下，每人的上网时间平均在2 、 3个小时左右，有意或无意两三次点击屏幕目标处很有可能，加上面对桌面（电脑）的动态及必须接触时间，注意力可以在一定程度上被消化在大脑中。
