Finally, to get the exclusive solution of a certain structure, the realization technology of electric and magnetic boundary conditions, as well as the quasi-periodic boundary condition is studied.

最后，对确定的高频结构，为了得到唯一确定的电磁场解，对基于有限积分理论的电边界、磁边界以及周期结构的准周期边界的数值实现技术进行了研究。

The hyperchaotic attractors along with chaotic, periodic and quasi-periodic attractors of these systems were obtained from circuit simulations.

电路仿真获得了这类系统的超混沌吸引子及混沌、周期和准周期吸引子。

All activities that are carried out according to the planned order re-lease for repetitive manufacturing can be triggered in the shop floor information cockpit.

该过程用于以下类型零部件的生产：一方面，该类零部件总是在流水线设备上以相同的方式进行生产的，有较长的生产周期；另一方面，其生产周期仅需要较少控制行为。

Through analysis on the structure of valence electron shell,the atom radius,the bonding orbital and other important parameters,this paper discusses the irregularity in the second circle of nonmetal elements and the irregular courses.

本文通过对第二周期元素价电子层结构、原子半径、成键轨道及其重要参数的分析，讨论了第二周期非金属元素的不规则现象，并且分析了产生这些不规则性的原因。

The Multi-stage Response Time is coming to be the core competition of the SC increasingly; however, the research of the optimization of logistic response time by LRP is still a vacuum.

目前在多阶响应周期日益成为供应链核心竞争力重要组成部分的今天，对于利用LRP优化物流响应周期的研究依然是空白。

Because the additional reference signal is not necessary, the delayed time is not related to the period of UPO and should not be the integral multiple of the period of UPO, so the presented method is simple and easy to apply.

由于不需要外加参考信号，延迟时间与UPO的周期无关，不必是UPO周期的整数倍，所以该方法简单易行。中国诺宇综合网http：//www.siaaa.com

In chapter 3,we discuss the existence of solutions for impulsive differential equations with two-point boundary condition.

通过使用脉冲不等式和分析方法，得到了一阶脉冲微分方程周期边值问题新的比较结果，借助所给的新的上下解，结合单调迭代技巧，建立了一阶脉冲微分方程周期边值问题极值解的存在结果。

The relation between periodic unit amounts and transmission properties of PDGS is given in the paper.

通过分析得出了PDGS结构的周期单元数与其传输特性之间的变化规律；NPDGS和PDGS相比，由于周期单元数和底面结构发生了很大的变化，从而导致其传输特性的表现形式相比于PDGS也产生了极大的差异，这样便能为新型DGS结构的分析和设计提供有力的指导。

The results indicate that weight factor had significantly effect on gait speed, steps per minute, gait cycle time, the ratio of stance time and swing time, maximal flexion angle of knee joint and the range of motion of elbow joint. Shelf height had significantly effects on hip flexion and elbow ROM. Box size factor had significantly effect on stride length, gait cycle time, the ratio of stance time and swing time, knee joint elbow ROM. For the muscle activity levels with EMG, load weight and shelf height both affected the %MVC significantly. When the subjects carrying a load of 14kg, the muscle activity and the subjective body part discomfort rating are both higher than that of 7kg. The box size had effect on the body part discomfort rating of upper extremity and back. For the kinetic and kinematics analysis, the shelf height around elbow height was better than the other two height levels.

研究结果显示，对步态时间与空间参数而言，重量因子显著影响步速、步频、步态周期时间与站立期摆荡期比值，箱型因子显著影响步长、步态周期时间与站立期摆荡期比值；关节活动度而言，重量显著影响膝关节最大弯曲角度、肘关节屈伸角度范围，高度因子显著影响髋关节前后倾角度、肘关节活动各变项，箱型因子影响膝关节弯曲最大最小值以及肘关节活动各变项，对肌肉活动度而言，重量与高度因子皆显著影响MVC%值，14公斤重者肌肉活动度与主观不舒适程度皆较7公斤者高，箱型因子虽无明显影响肌肉活动度，但是在主观不舒适程度上却明显影响上肢与背部，终点放置高度应设在肘高附近为佳。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
