在几百只已合成的新的苯二氮(?)类中仅少数几个被临床认可。虽然被采用的这些药物比原先药物有一定改进,但仍未达到减轻副作用的期望。最近发现中枢神经系统中存在着特殊的专一结合点。这使苯二氮革类催眠药研制有了有效的改进和进展。图1描述了理想催眠药应具有的药理学和治疗特征。睡眠机制与失眠习惯上和临床术语中失眠指睡眠短缺或质量不佳,或者指两者皆有。

＜正＞In the paper induction machine（IM） torque control is studied as an example of a three-dimensional non-holonomic integrator that includes drift *** expanding Brockett’s controller derived for the driftless systems,a control structure is proposed that guarantees natural adjustment of both the amplitude and the frequency modulation of the sinusoidal stator current *** rotor flux linkage vector is implicitly forced to track natural periodic orbits satisfying non-holonomic constraints of the *** features of the proposed control include fast dynamics of the torque response,maximal torque per amp ratio for nominal parameters,exponential stability,and robustness regarding expected parameter *** overall IM control scheme requires cascaded high-gain current controllers together with rotor flux linkage vector *** and experimental results illustrate the main characteristics of the proposed control with the emphasis on the quality of the generated machine torque and estimated rotor flux linkage orbits.
