From October 27 to October 30, 2006, Chinese Society of Engineering Thermophysics Branch of Heat and Mass Transfer Conference 2006 was convened at Academic Convention Center in Nanjing University of Science and Technology. There are many people such as associate Professor Zhang Li-Xin, Professor Yang Mo with graduate student Li Zi-yun, Liang Hao (studying in Tongji University), postgraduate doctor Huang Fu-quan, Wang Zhi-yun, etc. in the conference. At the meeting, they read out a number of papers. The graduate students above have practice or work under way at the R & D centers. The two of the papers, a 《a multi-tower type of test equipment for Cooling Tower》and 《a study of closed circuited cooler heat transfer method》were concerned about because relevant research in the heat and mass transfer is not common.
