The definition and stability criterion of resonant operating points in a CPT system have been described. A Poincarémapping model has been built up and its Jacobian matrix has been derived with the implicit function derivative rule and chain rule. Then the stability of the fixed points can be determined according to the eigenvalues of the the Jacobian matrix. It has been used to study an example push-pull CPT system with three resonant operating points.

文中给出了CPT系统中谐振点的定义及判断条件，建立了系统的庞加莱映射模型，并根据隐函数及复合函数求导法则，推导出了系统庞加莱映射周期不动点的雅可比矩阵，根据雅可比矩阵的特征值分布情况，即可判断各不动点的自治振荡稳定性。

Results: There is a significant difference between the levels of Hb、SF、 FEP of model groups and normal group. The syndrome of every treatment groups is much better than physiological saline solution group, and recover gradually. The Hb、 SF、 FEP and IL-2、 IL-6 were recover gradually. But the improvement of AS two solstices pill add chalybeate group is comparatively obvious. Conclusions: AS two solstices pill add chalybeate has obvious therapeutic action on IDA model rats.

结果：造模后，各组大鼠Hb、血清铁蛋白、红细胞游离原卟啉与正常对照有明显差异，经治疗后症状表现上明显较模型NS对照组好，且逐渐恢复，Hb、血清铁蛋白、红细胞游离原卟啉、血清IL-2、IL-6水平逐渐恢复正常，其中以加味二至丸加铁剂组和当归补血汤加铁剂组最为明显。

Their purchasing power was evident during the last major round of auctions in New York in November, when Asian collectors won several works, including Christie's $10.7 million Degas ballet scene,'Danseuses,' and Sotheby's $8.1 million Picasso portrait,'Femme au chapeau vert.

去年11月纽约的2009年最后一系列大型拍卖会期间，他们的购买力已经显而易见。亚洲收藏者赢得了许多艺术品，包括最终以1070万美元在佳士得拍到德加的名作《舞者》，花810万美元在苏富比购得毕加索的肖像画《戴帽子的女人》。

介绍了一种采用机顶盒方案的有线电视条件接收系统，它是基于射频处理的同步抑制分级群加解扰系统，具有群加扰系统的相对低成本和多级别利于收费节目开发的优点。

The deterministic neuronal firing model could simulate only the period adding bifurcation scenario in which period n bursting was changed into period n+1 bursting directly. The period adding bifurcation scenario and the new firing pattern similar to the experiment could be simulated in the stochastic Chay model.

确定性神经放电理论模型只能模拟周期n节律直接到周期n+1节律的加周期分岔序列；而随机Chay模型可以模拟实验中的加周期分岔过程和新节律。
