acritical怎么记

At the same time, we introduce a unified chaotic system with single parameter, called Lorenz system families, which contains the Lorenz and the Chen systems as two dual systems at the two extremes of its parameter spectrum, and acritical system as a transition system.

同时，提出了一个单参数的统一混沌系统&Lorenz系统族，它包含Lorenz系统和Chen系统作为参数区间的两个极端系统，临界系统作为一个过渡系统。

The results showed that applied stress has an effect on the hydrogen concentration distribution, and the applied stress has acritical value. When the applied stress exceeds this value, the hydrogen concentration in the prestressing steel wire will sharply increase following the stress.

结果表明外部施加应力对预应力钢丝中氢浓度的分布会产生影响，而且外部施加应力存在一个临界值，当超过此值时，预应力钢丝中的氢浓度随应力的增加而急剧增加。

In through-feed superfinishing of tapered roller, the guide roller plays a role in supporting, guiding and driving the rollers, and has acritical influence on accuracy and surface quality of tapered roller.

在圆锥滚子无心贯穿式超精研加工中，导辊对滚子具有支撑、引导和驱动三方面的作用，对滚子的加工精度与表面质量具有关键性的影响。
