发散序列

If a sequence is not convergent, it is divergent

如果一个序列不收敛，我们称它发散。

Calculate Lyapunov spectrum of series of R-R intervals and R-wave peaks with different physiological and pathological states. On the basis of Lyapunov spectrum, first propose the concept of Rate of Convergency-Divergency which can judge dynamics characters of the heart by both convergency and divergency.

计算了不同生理病理状态下动态心电图中RR间期和R波峰序列的Lyapunov指数谱，并以此为基础首次提出了收敛发散比的概念，它可以从收敛和发散两个方面衡量心脏系统的动力学特征。

In this paper the structure principle of GM(1, 1) was analyzed and the defect was pointed out that the traditional model only adapt to the data with exponential law, and only can fit for the monotonic data. The prediction is defected when there are two consecutive data unchanged, and 'a' is equal to 0.5 in prediction formula.

从传统GM(1，1)预测模型构造原理出发分析其存在的理论缺陷，此模型适用于具有较强指数规律的序列，只能描述单调变化过程，而且预测数据序列中出现连续两个相等值时将使得a等于0，会使预测数列发散致使预测失效。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
