| 1 | Multivariable temperature measurement and control system of large-scaled vertical quench furnace based on temperature field显示文摘A temperature control system of 31m vertical forced air-circulation quench furnace is proposed,which is a kind of equipment critical for thermal treatment of aluminum alloy components that are widely used in aerospace industry.For the effective operation of the furnace,it is essential to analyze the radial temperature distribution of the furnace.A set of thermodynamic balance equations modeling is established firstly.By utilizing the numerical analysis result to modify the temperature measurements,the control accuracy and precision of the temperature are truly guaranteed.Furthermore,the multivariable decoupling self-learning PID control algorithm based on the characteristics of strong coupling between the multi-zones in the large-scaled furnace is implemented to ensure the true homogeneity of the axial temperature distribution.Finally,the redundant structure composed of industrial control computers and touch panels leads to great improvement of system reliability. | XuanZHOU ShouyiYU JiangYU LiequanLIANG | 2004 | 控制理论与应用(英文版)2004，2，4： | 7 |

| 4 | Current Status of Alligator sinensis显示文摘The status about the resources of Alligator sinensis was investigated by sampling methods from August to September in 1994.In the National Nature Reserve for Chinese Alligator (ANNRCA) in Anhui,156 marking caves of alligators were found,77 alligators were seen by lighting-counting method and 253 by visiting.Analysing the results above,there were probably 667~740 alligators in ANNRCA and the population age pyramid was wide at the top and narrow at the base,which indicated that the survival situation of the population was serious.In the Chinese Alligator Reproduction Research Center of Anhui Province (CARRCAP),there were 4376 alligators by the end of the year 1994,of which 248 were breeding alligators,1542 recently hatched and 2586 of different ages.The population with an age pyramid that is narrow at the top and wide at the base shows that it has fast growing potential. | LI CHENYUAN SHAO MIN ZHU HONGXIN NIE JISHANThe Administrative Office of the National Nature Reserve for Chinese Alligator,Xuanzhou,Anhui,242034 | 1996 | 生物多样性1996，4，B10： | 0 |
