摘要:Research on a kind of mini high-performance auto-current-limiting device is shown in detail in this paper. The circuit philosoghy, function and features are introduced also.
摘要:The system response of the second - time vibration when acting and statics iron -cores touching together in the contact system of directive acting AD contactor was analyzed in this paper. The method of eliminating second - time vibration by improving mechanism was pointed out also. It provides the theoretical basis for design and improving AC contactor.

摘要:This article provides a new indirect determiation of DC Motor’s torque-speed Characteristic. According to the data of the experiments, We discussed the basis of each method and analysed the similarity of the results.
摘要:In the basic of the situation in the Muyu stone utensil machined, this paper presents an approach of turning replacing grinding for the Muyu stone utensil machined . The cutting feasibility is presented and mechanism study of Muyu stone utensils is carried out. The application results show the method of turning the Muyu stone utensils has a better quality of products and higher productivity than gringding ones.
摘要:The method of using false surface to solve descriptive geometry questions was shown in detail by means of illustrated examples in this paper. This method can simplify drawing process and improve drawing accuracy obviously.
摘要:This paper analyses three stages of athletes psychology exhaustion (Psychology shadow , Psychology disappointment and Psychology exhaustion), and then has a systematic study on every reasons of causing Psychology exhaustion of athletes.
