Simplier and more efficient ion extraction methods for atomic vapor laser isotope separation AVLIS were evaluated using a 2-D electron-equilibrium model to compute and compare three electrostatic methods the parallel electrode method, the Π type electrode method, and the improved M type electrode method.

为探索用于原子蒸气激光同位素分离AVLIS的简单有效的离子引出方法，用二维流体理论电子平衡模型计算比较了3种静电场方法平行板电场法，Π型电极法，改进M型电极法计算发现，二维流体理论电子平衡模型并不能很好地描述Π型电极法对另外两种静电场方法，计算了不同外加电压、不同的初始原子密度和不同的目标同位素丰度等条件下的离子引出情况从计算结果可以看出，改进M型电极法不论是从离子引出时间还是从碰撞损失率，都要比平行板电极法好得多当外加电压较高或初始原子密度较高时，这种好处就更加明显因此，改进M型电极法是一种可供实际采用的比较好的静电场方法

Applying LMI technique, quadratic stability theory, and H〓 control theory, three methods of robust stability analysis and robust controller design for uncertain fuzzy systems are proposed respectively. Among them, LMI based technique can analyze the uncertainties raised in the premises and in the consequent of fuzzy systems. The resulting stabilizing state feedback controllers have maximum stability margins for both kinds of uncertainties. Quadratic stability theory based approach can apply LMI technique and other methods to design fuzzy controllers. H〓 control theory based design can get H〓 controller with constant disturbance attenuation for each local subsystem. Using the given stability criterion of generalized systems, the robust stability of fuzzy systems can be checked.

其中，基于LMI的方法可分析由模糊系统的前件或后件引起的不确定性，得到的稳定的状态反馈控制器对这两类不确定性具有最大的稳定裕度；基于二次稳定理论的方法可应用LMI技术和其它方法设计模糊控制器；基于H〓控制理论的方法可得到各局部子系统具一定干扰抑制性能的鲁棒H〓控制器，而全局系统的鲁棒稳定性可应用所给出的稳定条件进行检验。

Methods Pure tone audiometry,SISI,ABLB and white-noise masking effect(Langenbeck's methods) audiometries were performed in 30 patients (44 ears) with sensorineural hearing loss with BOSCH audiometer made in Germany.
