Discriminating scheduling policies are applied to the 2 subsets . real - time tasks are also categorized 2 - dimentionally by arrival pattern ( periodic tasks vs . aperiodic tasks ) and deadline type ( hard real - time tasks , firm deadline tasks , etc . ) , and the policies to implement deadline monotonic algorithm on these types of tasks are discussed 并且将实时任务按照到达模式(周期性任务，非周期任务等)和截止时间类型(硬截止时间单调技术研究与实时调度模型的实现实时任务，固定截至时间任务等)两个维度进行了分类，讨论了如何利用截至时间单调算法处理不同类型的实时任务。

Deadline monotonic algorithm is studied from several perspectives including the development history of the theory , the scheduability test algorithm , priority inversion solutions , aperiodic task handling etc . and 2 important conclusions of the theory : static optimal property and the sufficient and necessary feasibility test , are discussed in proof form 从理论发展历史、可调度性测试方法、优先级倒置的处理、非周期任务的处理等几个方面对截止时间单调算法进行了研究。并对算法的两个重要结论：静态最优性和可调度性测试方法分别进行了证明和推导。
Using the general finite element programming package of ansys10 . 0 , the study of gabled frames beam - column end - plate connections is made , considering synthetically nonlinear ( material , geometry and contact ) , bolt pretension forces and ratio of axial compression stress to strength . elastic - plastic finite element analyses are carried out among 28 species of 3 series under monotonic loads , in order to discuss the influence of parameters including stiffness of end - plate , bolt diameter , friction coefficients and so on 本文使用通用有限元软件ansys10 . 0综合考虑了三重非线性(材料非线性、几何非线性以及状态非线性)的影响,同时考虑了螺栓预拉力的影响,对考虑端板厚度、端板加劲肋的设置、螺栓直径、摩擦系数等参数不同的3个系列(端板系列,螺栓直径系列,摩擦系数系列) 28个试件进行了有限元数值模拟,对连接节点的性能进行了分析研究。
The alloys , which were cold - worked followed by recrystallization annealing , display cyclic softening in the range of low strain because the cyclic stress - strain curve lies below the monotonic stress - strain curve , and show cyclic hardening in the range of high strain because the cyclic stress - strain curve lies above the monotonic stress - strain curve 在低应变范围，冷加工后经再结晶退火处理的错合金的循环应力一应变曲线位于单调拉伸曲线的下方，表现为循环软化;在高应变范围则位于单调拉伸曲线的上方，表现为循环硬化。
2 , the friction coefficient at the pitch point is not a monotonic quantity of the rational speed or the load , instead of having a maximum value . and the value of the friction coefficient is very small , its order of magnitude only being 10 - 3 . so , it is reasonable that the friction force on teeth surfaces are ignored when the gear - driven contact fatigue strength is designed 2 、当轮齿在节点啮合时，随着转速或载荷的变化，齿面摩擦系数并非呈单调变化，而是存在极值点;节点啮合处的齿面摩擦系数很小，其数量级为10一， ，因此在做齿轮强度设计时，忽略齿面摩擦力的影响是有理论根据的。
