The gentleman experienced some change of feeling ; he drew back his chair , took a newspaper from the table , and , glancing over it , said , in a colder voice , 达西也觉得心情有些两样，便把椅子拖后一点，从桌子上拿起一张报纸看了一眼，用一种比较冷静的声音说：
And of course , steven gerrard as a deep - lying striker : if this was a move intended to create confusion , it succeeded admirably , not least in the mind of gerrard 当然，还有杰拉德出任拖后前锋：如果这样的变化是故意为了制造烟幕的话，那么可以算是大获成功，当然杰拉德或许不会这么想。
Petr cech was given the all - clear earlier this week and could take his place in goal wearing special protective headgear , but is more likely to start on the bench 埃辛可能要代替被停赛的马克莱莱打拖后中场的位置，这样的安排让中卫位置上出现很大空档。但特里是否能够及时伤愈归队填补空缺还是未知。
S . instinctively fernand drew back his chair . " he is the cause of all this misery - i am quite sure of it , " whispered caderousse , who had never taken his eyes off fernand , to danglars 美塞苔丝已离开了老人的怀抱，正虚弱地倒在一张椅子上，碰巧弗尔南多的座位就在她的旁边，他本能地把他的椅子拖后了一点。
This paper develops a new vmi model with linear time varying demand and partial backlogging , which includes a single vendor and buyer and from raw material to final product 摘要考虑订货商面临线性时变需求和仓库在出空期间出现短缺量部分拖后的情况，提出了一个从原材料到产成品包括单一供应商和订货商的供应商管理库存模型，并进行了最优解仿真寻优计算。
I usually use my dmc and fcd in these roles , as the dmc holding the ball allows the defence to regroup and the fcd allows for the chance of wingers overlapping him which opens up more attacking angles 我通常使用我的防守中场和拖后前锋来担任这个角色，因为防守中场控球就能使得防线有机会重组，而拖后前锋控球就能使边锋创造出来的机会更加容易来自于好的角度。
This paper develops a deterministic inventory model for perishable items with a mixture of back orders and lost sales under inflation and time discounting , where the backlogged demand rate is dependent on the negative inventory level during the stock out period . the main differences from the existing related models are that the present model takes the maximum present value of profit in a repeatable order cycle as the objective function and proposes a more practical constraint of maximum customer - waiting time to ensure a proper customer service level . then the existence and the uniqueness of the solution to relevant systems are examined and a solution algorithm is shown to find the optimal replenishment policy . at last , some numerical examples are presented to illustrate the applicatioh of the model 本文建立了一种考虑通货膨胀与时间价值的变质性物品的库存模型,在模型中允许短缺发生且拖后的需求速率与在缺货期间已经发生的缺货量有关.和已有相关模型的主要区别在于本模型把一个可重复的订货周期内的最大平均利润的净现值作为目标函数,且增加了在缺货期间最长顾客等待时间的限制,以确保库存系统拥有较高的服务水平.然后讨论了模型最优解的存在性与唯一性,并提供了寻求模型整体最优解的算法.最后用实例说明了此模型在实际中的应用
