Energy Assessement for Procedure Rationality of Recycling Materials from Wastes

The mathematical relationship for assessing total energy consumption within a material life cycle is presented in this paper. According to the relationship,the procedure rationality of recycling waste may be assessed quantitatively.     

A New Adaptive Sequential Diagnosis Algorithm in the PMC Model

We present an adaptive algorithm for sequential diagnosis in the PMC model,which can directly identify a faulty processor without first identifying a fault-free processor.     

Studies on the Oxidation of Weathered Coal with Nitric Acid

A raseach has been done on the possibility of producing nitriochumic acid fromweathered coal of Nantong,Sichuan,oxidised by nithic acid.The optimun reacting conditions,whichare found through the way of orthogonal experiment,are suggested as follows:concentration ofHON3 35%,rate of HON3 to coal 3.5,reacting take 15 min,and reaction temperature 369 K. Thecomposition of product is Wf 2. 91 %;Ag 14.06%;HAg 78.28%;Ng 1.62%.     

The Software Implementation of Neural Network Fuzzy Inference Cooperation System

This poper sets up a new Neural Network Fuzzy inference Cooperation system which is based on fuzzy inference principle in Expert Systems,take advantage of the powerful learning function, the little sensitivity to input layer's samples,and the fast convergence and so on in FCBP and take advantage of the good sort property and good suit property to fuzzy value in MFART Network.     

Practical Criterion for Voltage Stability of Substation

This paper presents a new practical criterion for voltage stability based on the real-time information at the substation and the quasi-time information from power system.By using the criterion,it is effective to predict the bus voltage stability margin.This is of great importance to raise the security operation level and prevent voltage collapse.The practical criterion for voltage stability is tested on the IEEE-14-bus test system.It needs less calculation time and is very suitable for real-time control of power systems.     

The Generalized Conjugate Direction Method for Constrained Optimization A Geometrical Approech

The conjugate direction method for solving the unconstrained optimization problem is extended to solving the constrained optimization problem by method of differential geomtry.By inducing a new class of affine connections on a constrained sub-manifold, the primary constrched optilnhation problem is converted to a unconstrained local quadratic programming problem.Based on the definition and construction of a new class of generalized conjugate directions, it isproved that optimum value of the primary constrained optimization problem must be located on thegeodesic line which is formed by the conjugate directions mentioned above and can be reached withinfinite searching step. Therefore a new curve search algorithm with generalized conjugate directions isput forward.     

The Method of Diagnosing Brain-dysfunction Based on Membership Function and BP Neural Network

Membership functions.formed with the characteristic values obtained by applying the continuous reaction time (CRT) theory from controls and heptic encephalopthy and proposedin this paper.whith these membership functions,the CRT data to be diagnosed are calculated in advance,and then discriminated by BP meural network to differentiate patients with or without braindysfunction.The troubles of low accuracy and efficiency,encountered in training BP network withfuzzy samples.scattered data and extended samples,are solved.

‘福山包头’大白菜叶柄黑点病发生特点及抗性分析

以‘福山包头’大白菜为试材,利用田间调查、显微观察和叶片离体培养的方法,对‘福山包头’系列大白菜叶柄黑点病的发生特点及抗性进行了研究,以期为改善‘福山包头’大白菜抗病性及新品种选育提供参考依据。结果表明:(1)大白菜叶柄黑点病主要发生于叶柄表皮细胞且起始于细胞周质或细胞壁,该病可发生于大白菜的整个生育期,且进入包心期后发展较快;(2)氮素能诱导叶柄黑点病的发生,且铵态氮较硝态氮诱导效果更明显;(3)氮素浓度与叶柄黑点病的发病程度呈正相关,但氮素并不是影响叶柄黑点病发生的唯一因素;(4)‘福山包头’系列大白菜种质资源中,‘福东2号’‘福山82’对叶柄黑点病的抗性较强,‘福小87-13-13’‘皱福’的抗性较弱。
