They work day after night , repeating monotonous tasks just like machines , they have to finish their tasks at the highest speed , since maximum output per unit time means that they will earn as much money as possible ; but in fact , even that is rather slim 他们日夜加班,像机器一样重复着单调的动作一一手中的活计必须以最快的速度完成,因为最大可能地提高单位时间里的工作效率即意味着他们在月底能拿到最多可能的薪水;而事实上,即便这“最多”也仍旧少得可怜。
Circulation for transferring record then , based on the above limitations , this paper proposes a dynamic load balancing method . through the simulation of the change over time of the traffic of customer data , it draws a comparison in the deviation of the change over time of the traffic in a certain sdm ( service data module ) with respect to that of the average traffic of all modules between old method and new method . the load imbalance ratio , the number of records transferred per unit time and the reduction of number of modules are evaluated 本论文针对上述两个问题,提出一种改进的负载平衡方法,通过对用户数据流量随时间变化的仿真,比较了记录迁移方法改进前后每一模块的流量变化与所有模块平均流量变化的趋近程度,同时还对几个重要参数:模块数量缩减率、负载不平衡比和单位时间内记录迁移数量,它们之间的关系进行讨论,得出改进后的记录迁移方法能够达到动态平衡负载的效果。
Considering the vectorial property of the time - average energy flow density , a new extensive definition of the light intensity has been proposed . it is expressed as the time average of the amount of energy which crosses in a unit time and a unit area , so it can be applied to measure quantity of the light intensity at any curved surface 对于非傍轴标量光场能量传输规律的描述则必须考虑其能流密度的矢量特性,应当采用光强的精确定义? ?单位时间单位面积上所流过能量的时间平均值来精确地描述某一横截面上的能流,这也与光强的实际测量值是一致的。
Advanced algebra traditional teaching model to keep pace with the times , practice has proved that higher algebra teaching computer - aided teaching some skills , not only to raise the utilization rate of hours , but can be greatly increased unit time to teach students knowledge of the volume of information , expanding the knowledge base , be conducive to improving the quality of teaching advanced algebra 摘要高等代数传统教学模式要与时俱进,实践证明,在高等代数的教学中应用计算机辅助教学的一些技巧,不但可以提高课时利用率,而且可以大大增加单位时间内给学生传授知识的信息量,扩大学生的知识面,有利于提高高等代数教学质量。
The second section is to discuss the capacity coordination of international multi - transport , in the macro angle , we may found that the layout coordination is a research of matrix structure , while the capacity coordination is to research the transport capacity in the max unit time under the reasonable organization and design . the third section discusses the technology and equipment coordination 第二节对国际多式联运系统能力协调进行研究,从宏观上我们可以这样认为,布局协调是区域间能力协调问题,是一个矩阵结构的研究,而能力协调是指对系统设施在合理组织、全面规划、协调配合下所形成的最大单位时间的运输量的研究。
The exhaust noise contains complex noise elements , including the exhaust noise with a base frequency measured in the number of exhausts in unit time , the resonance noise of the gas column in the pipe , the gas stream blowing noise at the exhaust manifold , the exhaust gas jetting and impact noise , the helmholtz resonance noise of the cylinder , the karman eddy noise and the turbulent noise inside the exhaust system 排气噪声包含了复杂的噪声成分:以单位时间内排气次数为基频的排气噪声、管道内气柱共振噪声、排气歧管处的气流吹气噪声、废气喷注和冲击噪声、汽缸的亥姆霍兹共振噪声、卡门涡流噪声及排气系统内部的湍流噪声等。
It is impossible to bargain one - to - one for all sellers and buyers in real life . because different buyers cannot be distinguished , the seller may bargain with many buyers . at that time the effective interval changes , the seller tries to maximize his income in unit time , while buyers make decision independently 但是,现实中的卖者和买者之间可能并不一定都是一对一的进行讨价还价,由于不能区分不同的买者,卖者可能会面对一对多进行讨价还价的情形,此时讨价还价双方的有效区间会发生一定的变化,而卖者是从自身的单位时间内收益最大化进行考虑,买者则是单独决策。
It defines the implication of the cost and analyses the features , the constitutes and the influencing factors of the cost and studies the ways and strategies to cut down the customization cost of the products in the production of mass customization . the author raises that the customization cost is related with the location , numbers of the customization spots and with the time the customization costs and with the unit time cost of the customization means . then the paper detailedly studies the customization cost from both qualitative and quantitative angles and shows the mathematics model aiming for the customization batch which is " 1 " and not " 1 " 界定了大规模定制生产中成本的含义,分析和研究了大规模定制生产中成本的特点、构成、影响因素以及降低大规模定制生产中定制产品的定制成本的途径和策略,提出了大规模定制生产中的定制成本与定制点的位置、数量、定制所花的时间以及定制手段的单位时间成本的关系,并从定性和定量两个方面对大规模定制生产中的定制成本进行了详细的分析研究,分别针对定制批量为1和不为1的情况建立了数学模型。
