This paper studies on the impression cylinder of J2108 offset press. With finite element method, deflection character of cylinder is achieved in static and dynamic load. Active-compensation to improve flexing-change of cylinder is bring forward, and its compensation character is simulated.

本文以J2108型胶印机压印滚筒为研究对象，通过有限元分析获得滚筒动静态挠曲特性，提出用主动补偿方法改善滚筒挠曲变形，并仿真分析了补偿特性。

Richards Bay in South Africa and the Australian coal terminals at Dalrymple Bay, Hay Point, Gladstone and Newcastle endure constraints that force vessels to wait weeks before they are able to load their cargo.

南非的理查兹湾和达尔林普尔湾的澳大利亚运煤中心，海波因特，格拉德斯通和纽卡斯尔等煤炭码头都在遭遇阻碍，船只往往要等上几个星期后才能装货。

Introducing the parametric plane, the stable map of Hill equation was drawn, i. e. the map of damped oscillation of crane load.

最后引入参数平面，绘制Hill方程稳定图，即起重机吊重做减幅摆动的图示。

We can also see that because damping factor is a ratio that requires the load impedance to compute, it must be stated against some known impedance to be meaningful.

我们还可以看到因为阻尼因子是一个比率值，而且需要负载阻抗已知才能够进行计算，所以阻尼因子必须和某一已知的阻抗同时具明才有意义。

Technically, the damping factor is the specified load impedance (in use, that'd be the speaker system) divided by the amplifier's output impedance.

技术上，阻尼因子就是指定的负载阻抗（实践中，也就是扬声器系统）除以放大器的输出阻抗。

调整Rockwell测试仪的表盘，使得在机器上没有样品或没有压头降载荷施加到蛅座上时，操作柄在4-5秒内完成其行程。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
