limit cycle

基本解释

The existence of a limit cycle was proved.
证明了极限环和周期解的存在性。
This instability is intermittent so that the device can operate in expected steady states or limit cycle oscillation states by slightly adjusting the parameter.
这种不稳定是阵发性的，适当的调节控制参量，可使器件工作在所需的定态或极限环振荡态上；
The experimental results show that the direct compensation can eliminate the limit cycle, and improve the precision of the system combine precision compensation.
实验结果证明，直接补偿算法能消除极限环，直接补偿算法配合精度补偿可以消除间隙非线性引起的极限环并提高系统精度。

Furthermore, any limit on deficits should take into account the economic cycle.

One has to anticipate a continuing negative clean tech funding environment (and a future up cycle is likely too) and keep in mind that this will limit the ability for these companies to raise equity financing in the future.

极限环
In this paper,we present unioueness theorem of limit cycle of system =(y),=-g(x)-f(x)y. The result improves and extends the result in 1.
本文给出系统＝（y），＝-g（x）-f（x）y条件较弱的极限环唯一性定理。
