后平衡

Stability analysis of nonlinear magnetic suspension, the magnetic suspension system model was found based on electromagnet dynamics and voltage balance of the electromagnet coil; The feedback of position and velocity and current are used as the control variable; After the control rule was applied to the electromagnetic system, the louts criterion was used to get the range of the control parameter in which the system was steady-going.

非线性磁悬浮系统的稳定性分析，通过电磁铁动力学和电磁线圈的电压平衡方程，建立磁悬浮系统基本模型。求出系统奇点后，通过系统线性展开求出系统矩阵。用PD控制外加电流反馈量，将控制规律带入系统模型方程组求出矩阵的特征方程，由劳斯判据得知非线性系统稳定的位置反馈系数及取值范围。

Contrarily,if the stress of the wellbole is more than the rock strength,the wellbore will not be in stability. As the pressure of air drilling is so small that the pressure of well pit can not balance the layer pressure when the wellbore formated, and the stability of wellbore only depends on the rocks nature strength.

由于空气钻井过程中井筒内产生的压力很小，井眼形成后，井筒内压力无法平衡地层产生的应力，井壁是否稳定主要取决于岩石本身固有的强度性质。

Brain temperature in the unregulated group dropped to 34.0 +/- 0.4 degrees C at 1 h. The hypothermic group had improed motor function assessed using beam balance and inclined plane tests s.

未调温度组的脑温1小时后降低到34.0 +/- 0.4°，用游梁平衡和倾泻平面测试（beam balance and inclined plane tests）评估，低温组的运动功能比正常温度组有改善， 5周时 CA1海马神经元存活数目增加与低温的程度相关。
