To guarantee the live, unsettled and non-circulate before dealing with intactly Using TTL life time parameter, duplicate test parameter, circulation parameter to control the spread of message.The design of the model is a complicated and big problem.

为了确保查询消息在进行完整处理之前是存活的、未处理过的而且是非循环的，使用了TTL存活时间参数、复制测试参数、循环参数来进行传播控制。

Maximum shear stress may be transfered into maximum shear strain by simple cyclic constitutive relation for low-cycle fatigue of controlling strain. Manson-Coffin type equation is derived by considering effect of nonproportional additional hardening.

对于应变控制的低周疲劳，最大剪应力参量通过简单的循环本构关系转换为最大剪应变参量，由此导出了Manson—Coffin型的公式，考虑了非比例循环附加强化对低周疲劳寿命的影响。

The methods and devices to control the circulation solid flow pneumatically are studied in this paper.

Methods After giving out the relative increment matrix for keeping the system steady, the paper introduces the detail methods for the control of oxygen concentration after unchaining coupling in assistant breathing equipment cycled with mixed gases of helium and oxygen.

目的是通过循环式氦氧混合气辅助呼吸装置设计中的氧浓度解耦控制技术的研究，探索循环混合气技术在呼吸支持设备中应用的可行性及其重要意义。

The test results show that the crispest HAZ occurs in the process of welding of the 14MnNbq steel on the first heat circulation submerged welding overheat zone and the second heat circulation submerged welding overheat zone plus the not entirely re crystallized zone. The 14MnNbq steel has a tendency of being crisper due to overheat than the SM490C steel is. In order to ensure the toughness of the welding HAZ′s, the welding wire capacity should be properly controlled during welding.

由试验结果表明，14MnNbq钢焊接HAZ最脆区出现在一次热循环的埋弧焊过热区及二次热循环的埋弧焊过热区+不完全重结晶区；14MnNbq钢比SM490C钢有更强的过热脆化倾向，为确保焊接热影响区韧性，焊接时应适当控制焊接线能量。

Differential pressure control point of control: heating pipe network because of distance, signal transmission is not easy to achieve, or achieve a higher cost, the use of calculated values converted to the main circulating pump import and export; or in the pressure control point for backwater install pressure gauge, pressure gauge reference value to adjust the import and export of the main circulating pump pressure.

压差控制点处压差的控制：由于供热管网距离较远，信号传输不易实现或实现成本较高，采用计算值折算到主循环泵进出口；或在压差控制点供回水管安装压力表，参考压力表数值调整主循环泵进出口的压差。

The loop will execute while the switch on the front panel is FALSE and stop when the switch becomes TRUE.

当前面板的控制端子为&FALSE&时循环将持续运行，当开关为&TURE&时循环将停止。
