Abstract: A coaxial double-rotor variable-speed electromagnetic drive includes an external rotor, an end cover, a load shaft, a stator, and an internal rotor, the external rotor, the load shaft, the stator, and the internal rotor being coaxially arranged. The end cover includes a first end cover and a second end cover that are respectively disposed at two ends of the drive, the external rotor is slidably connected to the two end covers separately by bearings, the load shaft is slidably connected to the first end cover and the inner side of the external rotor separately by bearings, the stator is fixed on the inner side of the first end cover and disposed inside the external rotor, air gaps are kept separately between the stator and the internal rotor and between the stator and the external rotor, the internal rotor is sleeved on the load shaft and is disposed inside the stator.

Abstract: An application of a combination of traditional Chinese medicine in the preparation of a potassium ion channel modulating agent. The combination of traditional Chinese medicine is made up of traditional Chinese medicine raw materials according to the following weight proportion: Coptidis Rhizoma 250˜450; Pinelliae Rhizoma 150˜350; Poria 150˜450; Aurantii Fructus Immaturus 62˜265; Dichroae Radix 150˜350; Nelumbinis Plumula 10˜70; Sophorae Flavescentis Radix 150˜350; Artemisiae Annuae Herba 150˜350; Ginseng Radix Et Rhizoma 65˜265; Ophiopogonis Radix 150˜350; and Glycyrrhizae Radix Et Rhizoma 62˜265.

Abstract: The present invention provides an application of a combination of traditional Chinese medicine in the preparation of a potassium ion channel modulating agent. The combination of traditional Chinese medicine is made up of traditional Chinese medicine raw materials according to the following weight proportion: Coptidis Rhizoma 250~450 Sophorae Flavescentis 150~350 Radix Pinelliae Rhizoma 150~350 Artemisiae Annuae Herba 150~350 Poria 150~450 Ginseng Radix Et Rhizoma ?65~265 Aurantii Fructus ?65~265 Ophiopogonis Radix 150~350 Immaturus Dichroae Radix 150~350 Glycyrrhizae Radix Et ?65~265 Nelumbinis Plumula 10~70 Rhizoma The combination of traditional Chinese medicine of the present invention could prolong the action potential interval of the myocardial cells, thereby prolong the refractory period of myocardial electrical activity. It has the function of inhibiting arrhythmia induced by excitatory reentry without toxic side effects.
