Application of Increasing PID Controlling Method in Temperature Controlling System
YAN Xiao-zhao,ZHANG Xing-guo(School of Mechanical Engineering,Nantong University,Nantong 226007,China)Temperature control is widely applied in scientific experiments and industrial processes.However,the temperature control system has characteristics of being nonlinear,time-varying and has hysteretic complicated large inertial system,and the effect of control is closely related to the algorithms adopted.In this paper,an experimental temperature control system is developed to meet the requirement of innovative ability training for mechatronic undergraduates.An increasing PID control algorithm is designed.The experimental results prove that the effect of the designed algorithm is better than the traditional PID algorithm.

Overview of SERS
LAN Yan-na,ZHOULing (Nantong Institute of Technology,Nantong226007,China)The principle of Raman spectrumis expounded first.Then the characteristics of SERS effect in experiment is summaˉrized and the mechanism of SERS is described.It's an accepted viewthat the mechanism of electromagnetic enhancement and the mechanismof chemical enhancement are both in existence.But which one is more important in different experiment depends on specific condition.
Application of ANSYS to Reinforced Concrete Beam
WANG Ya-ping 1,CHEN Jian-ping 2 ,CHEN Wu-zhou 3(1.Nantong Institute of Technology,Nantong226007,China;2.Nantong Architectural Design Institute of Industry,Nantong226001,China;3.Nantong Water Conservancy Construction Company,Nantong226005,China)In this article,taking features of reinforced concrete into account ,FEM software of ANSYS was used to calculate the beam' s deformation and the stress and strain of the normal section.At last,the answers to ANSYS(crack length,stress of reinforc-ing bar and concrete)and theoretical answers were compared in search of reasons and ways or measures that can amend it.
Research Status of the Bond - slip between Reinforcing Steel Bar and Concrete
CHEN Jian - ping, XU Xun - qian, BAG Hua (1. Zhuyuan Design Company Ltd., Nantong 226000, China; 2. Nantong University, Nantong 226007, China)Many researchers have been devoting themselves to the study of the bond - slip between reinforcing steel bar and concrete . However, because of the complexity of the transferring - force on the interface between them, a number of factors and different tests and diverse surveys have led to sporadic experimental data, so we haven' t had any uniform formula up to the present. In this paper, external and internal research status of the tests, the constitutive relationship and FEM analysis are discussed briefly one by one.
Analysis of Information Security in Nantong Power System Dispatching Automation System
CHEN Guo-hua,MAO Wei-dong (Nantong Electric Power Supply Branch,Jiangsu Power Company Nantong226006,China)The threats to information security in Nantong power system dispatching automation system are analyzed.In the light of the computer structure in power system dispatching automation system,some security strategies are proposed such as network security subarea,physical gap,private network,firewall technology measures and some security control measures.

ZHUQi-xin,WUJian-guo,LUGuo-ping,DUJun,ZHOUHui,JIANG Ping (Nantong Institute of Technology,Nantong226007,China)The conceptof network control systems is presented in this paper.Some basic problems including time-varying transˉmission period,network scheduling,network induced delay,single-packet and multiple-transmission,wrong order of netˉwork packet,dropping network packets,driving mode of node and clock synchronization are discussed.Network induced delay is analyzed too.
The State and Prospects for Copper Tailings as Resources
CHEN Yu - feng, LU Xiao - yan (1. Hehai University, Nanjing 210098, China; 2. Nantong University, Nantong 226007, China)This paper expatiates the dangers caused by copper tailings, and their utilization state for copper tailings is summarized . In the end, the measures of using copper tailings in a reasonable way are put forward.
The Photoluminescence Spectra and the Energy Level of ZnO Thin Films
MIAO Shi-qun (Nantong Institute of Technology,Nantong 226007,China)In this paper, some photoluminescence spectra of ZnO thin films are compared with the energy level as has been worked out with the full - potential linear muffin - tin orbital method (FP - LMTO) . The paper concludes that the emission of the red light is rekted to oxygen vacancies and zinc intervals, while that of the green and the blue light to zinc intervals and zinc vacancies a well as oxygen vacancies.
