The stability conditions are extracted by analyzing the open-loop transfer function of three-order charge PLL. It shows that the stability are mainly affected by the ratio of the two capacitors of the two-order loop filter, loop damping factor and loop zero. The ranges of these parameters are also calculated.

通过分析三阶电荷泵锁相环的开环传输函数来确定系统的稳定性条件，得出了系统的稳定性主要与二阶滤波器两电容的比值、系统的衰减因子以及系统的零点分布有关，并计算出在不产生过冲的情况下这些值的范围。

The most powerful tool of tribology study is experiment and all kinds of friction testing system is designed and manufactured for friction test.

但在这些摩擦试验系统上都无法实现摩擦速度实时改变的试验，为了验证摩擦速度变化对摩擦磨损情况的影响，同时也为了研究周期性波动摩擦速度变化下的摩擦材料性能和特点，从探讨非匀速摩擦磨损过程的构思出发，提出构建一种非匀速摩擦磨损试验装置。

Because the cactus stem is very thick, which can store a lot of water, the water can dry it in extreme cases of life-sustaining.

因为仙人掌的茎很厚，里面能储藏了很多水份，这些水份能使它在极度缺水的情况下维持生命。

These bridges—regarded as the linchpins of seabasing—will remain stable in swells of up to 2 metres.

这些桥被看作是构成海上基地的关键因素——能够在2米高海浪的情况下保持桥面稳定。

If nitrogen is present as single atoms, it would hint that the diamonds were produced rapidly and at relatively low temperature - as might happen if the diamonds formed from pockets of graphite in the zircons in a single, rapid event.

如果氮元素以单个原子存在，这将暗示这些钻石是在相对比较低温的情况下快速形成的。

In extreme cases, these conflicts can lead to more violent behavior, such as school shootings.

在这种极端情况下，这些冲突很有可能会导致更加暴力的行为发生，像校园枪杀事件等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
