| 7 | History of Psychology in China: Contributions, Challenges, and Future显示文摘心理学的历史使三成为主要贡献:(1 ) 在中国支持心理学的发展;(2 ) 作为一个学术学科建立中国心理学的历史;(3 ) 在训练中国心理学家的下一代起一个重要作用。这个努力面对众多的挑战,包括在教小时的大学生的减小,衰退在研究生水平,在研究的有限革新,和金融支持的缺乏的注册。从主要的这些挑战茎在中国学术估计系统,放在试验性的心理学上的更大的重量,和一个少数变化为研究人员的机会。为了探讨这些担心,当也介绍它的调查结果给公众时,在中国的心理学的历史应该使中国心理学的历史成为它的研究优先级,并且开发创新的教和研究途径。 | Wendeng Yang Haosheng Ye | 2017 | Frontiers of History in China2017，12，2： | 0 |
| 8 | Research on and Design of Mechanical System with Optimal Cutting Movement Trajectory of Energy-Saving Stone-Sawing Machine显示文摘The technique of cutting slabstone with stone-sawi ng machine is analyzed completely. A new kind of cutting movement trajectory is gi ven whose actual cutting efficiency is near to 100%. It can reduce the energy w earing greatly, and the surface quality of the product is improved to the utmost extent. The design mechanism of the optimal cutting movement trajectory system structure is analyzed incisively. At the same time, the principle of the complex movement of horizontal movement and swing is researched. The optimal design scheme of th e cutting movement trajectory system structure is set up. The choice method to g et the superior value of the movement system structure is found. The mathematics function formula is established which exhibits the relationship between the par ameter of the complex movement structure and that of the system movement structu re. By the formula, the precision value of the offset can be figured out. The r ule is adapted to different types of energy-saving stone-sawing machines. The complex movement structure of horizontal movement and swing is designed to f ulfill the cutting movement. It can make the saw frame move up with the hanging pod deviating from the vertical direction. At the same time, the saw frame have a down-movement. Then the sum of the two movements is near to zero, and the saw blade and the stone can keep in touch during the whole horizontal cutting. The result is that the actual cutting efficiency is 100%. Also, when the hanging pod moves to the limited position, the saw frame can keep the original inertia, and continue to swing up. It makes the back-cutting have high energy-storing. The optimal design of the eccentricity balance wheel is done. The mathematics fo rmula for expressing the movement system structure is deduced. The calculation m ethod and formula is set up which is used to get the value of important componen ts such as offset. The choice method and formula of elasticity distortion coeffi cient is set up when the saw frame moves smoothly. It is concluded that the offs et is the key dimension to actualize the optimal cutting movement trajectory. The resolving of the technical problems discussed above offers a theoretic and technical basis for optimal design of energy-saving stone-sawing machines. | WANG Ji-rong 1, LI Lan-ji 1, LI Jun 1,3, LI Hua 2, ZHONG Yun-qing 3 (1.Qingdao University, Qingdao 266071, China 2.Wendeng Foreign Economic and Trade Corp, Wendeng 264400, China 3.Qingdao University of Science and Technology, Qingdao 266042, China) | 2002 | 厦门大学学报(自然科学版)2002，41，S1： | 0 |
| 9 | Defects and Electron Densities in TiAl-based Alloys Containing Mn and Cu Studied by Positron Annihilation显示文摘The defects and electron densities in Ti50Al50, Ti50Al48Mn2 and Ti50Al48Cu2 alloys have been studied by positron lifetime measurements. The results show that the free electron density in the bulk of binary TiAl alloy is lower than that of pure Ti or Al metal. The open volume of defects on the grain boundaries of binary TiAl alloy is larger than that of a monovacancy of Al metal. The additions of Mn and Cu into Ti-rich TiAl alloy will increase the free electron densities in the bulk and the grain boundary simultaneously, since one Mn atom or Cu atom which occupies the Al atom site provides more free electrons participating metallic bonds than those provided by an Al atom. It is also found the free electron density in the grain boundary of Ti50Al48Cu2 is higher than that of Ti50Al48Mn2 alloy, while the free electron density in the bulk of Ti50Al48Cu2 is lower than that of Ti50Al48Mn2 alloy. The behaviors of Mn and Cu atoms in TiAl alloy have been discussed. | WenDENG DingkangXIONG JingyangWang LiangyueXIONG MingzhouCAO ChiweiLUNG | 2003 | Journal of Materials Science & Technology2003，19，2： | 0 |
