To analyze the academic characteristics and medication rules of traditional Chinese medical master Liu Zu-yi for treating insomnia. Totally 178 cases of insomnia treated by Professor Liu were collected,and the treatment data were input into traditional Chinese medicine inheritance support system( TCMISS) by using data mining methods,such as essential information,frequency statistics of symptoms,syndrome type statistics,extraction of syndrome elements,frequency statistics of drugs; and four properties and five tastes of drugs,distribution of meridians,regularity of prescriptions,new prescription analysis were mined. It was found that the most commonly used drugs( over 100 times) were Albiziae Cortex,Longgu,Polygoni Multiflori Caulis,Ostreae Concha,Ziziphi Spinosae Semen,Crataegi Fructus; the commonly used couplet medicines were Longgu-Ostreae Concha,Ziziphi Spinosae Semen-Polygoni Multiflori Caulis,Ziziphi Spinosae Semen-Albiziae Cortex-Polygoni Multiflori Caulis; and seven new prescriptions in treating insomnia were explored,such as prescriptions containing Hordei Fructus Germinatus,Ziziphi Spinosae Semen,Galli Gigerii Endothelium Corneum,Rehmanniae Radix,Lilii Bulbus. Based on the introduction and discussion of Professor Liu's academic views and characteristics on insomnia treatment and the illustrative evidences added to the typical case list,this paper combines the academic characteristics,data support and typical medical records to verify each other,and objectively summarizes his academic experience for treating insomnia. Treatment shall focus on the primary cause of disease in three aspects; syndrome differentiation shall distinguish between excessive disease and deficient disease; therapy shall reinforce deficiency and reduce diarrhea,regulate the five internal organs,and emphasizes the heart and liver,particularly the liver; medication shall focus on the drugs for calming the mind and protecting the stomach and spleen,which are commonly combined with three types of traditional Chinese medicine with effect in introducing Yangqi( Pinelliae Rhizoma Praeparatum,Prunellae Spica,Polygoni Multiflori Caulis) and restraining Yangqi( Longgu,Ostreae Concha,Ziziphi Spinosae Semen); nursing care focuses on preserving the body and tranquilizing the mind by means of three methods for tranquilizing the mind and three methods for preserving the body.

In this study, taking the advantage of ultrasonic motors, a locking device driven by ultrasonic motor for magnetic bearing flywheel has been manufacture and evaluated. A locking device is used to eliminate the gap between the rotor and the stator of magnetic bearing flywheel in order to prevent it from shock and vibration. Since the present locking devices driven by initiating explosive device or magnetic motor have the disadvantages such as high, shock, large size, and heavy weight. The system of locking device includes mechanical structure and motion control. The driving component of mechanical structure applies a traveling rotary wave ultrasonic motor (TRUM). The transmission employs worm gear so as to drive the executive body. Then the flywheel is protected. The power input of the ultrasonic motor is stable and the temperature rise of ultrasonic motor is 4°C. The force of actuated clutch is 17.1 N along with the radial. So the locking device has a highly-efficient locking performance.

5 at.% Mn-doped and undoped, 200 nm thick BaTiO3 thin films have been grown under different oxygen partial pressures by pulsed laser deposition on Pt/sapphire substrates. X-ray diffraction (XRD) measurements reveal the same polycrystalline single-phase perovskite structure for all the thin films despite the different oxygen partial pressure, while their preferred orientation strongly depends on the oxygen partial pressure. The 5 at. % Mn-doping decreases the dielectric loss of the Mn-doped BaTiO3 thin films, however, their relative permittivity is also decreased. Ferroelectricity has been probed on the Mn-doped and undoped BaTiO3 thin films grown under relatively high oxygen partial pressure. A ferromagnetic coupling of the Mn dopant ions has been probed at room tempetature on the Mn-doped BaTiO3 thin films prepared under low oxygen partial pressure and is understood in terms of the bound magnetic polaron model.
