Multiple Layer BP Neural Network for Fuzzy Calculating

The FCBP(Fuzzy calculating BP) algorithm which is proposed by this paper hasovercome the sensitivity for samples,reduced the number of input layer's samples,lightened the burden of input layer.it is suitable to fuzzy inference and pattern recognition.     

Experimental Study on the Extended Length of Negative Reinforcement Cut-in Phases in Continuous Beams

In this paper through the static loading tests of 6 inflexion zones and 2 cantilever zones in full-size constrained R/C beams, the stress performance in rebars cut-in-phases and subjected to negative moment is studied. The stress properties of extended length of rebars with different shear-span ratiosare analysed on basis of the full measurement of strain distributions combined with the investigation on state and regularity of the diagonal cracks development and series of new knowledge are obtained. It is found that current Concrete Design Code provisions on the extended length are inadequate for the high shear-span ratio and superfluous for the low shear-span ratio. The theoretical and experimental foundations are provided for determining proper value of extended length for rebars cut-in-phases.

超级稻“三定”栽培法研究 Ⅱ.不同施肥量对超级杂交稻产量及生长生理特性的影响

2004—2005年在长沙（28°13′N）采用低肥（N 135kg/hm2、P 29.7kg/hm2、K 112.1kg/hm2）、中肥（N 180kg/hm2、P 39.6kg/hm2、K 149.4kg/hm2）、高肥（N 225kg/hm2、P 49.5kg/hm2、K 186.8kg/hm2）3种施肥水平，对超级杂交稻两优293和准两优527的产量及生长生理特性进行了比较研究。结果表明：在试验范围内不同施肥量处理间超级稻产量及有效穗、每穗粒数、结实率等产量构成差异不显著，2年平均产量以中肥处理最高，其中准两优527为9.03t/hm2，两优293为7.28t/hm2；不同年际间超级稻产量及有效穗、每穗粒数、结实率等产量构成差异显著；超级杂交稻准两优527和两优293的适宜氮肥用量为150~180kg/hm2。与准两优527比较，两优293茎秆粗壮，根系发达、根系活力强、分蘖力强、但分蘖成穗率不高，而准两优527前中期生长平稳，分蘖成穗率高，抽穗后光合产物积累多和运转率高，有利于高产形成，但不抗倒伏，生产上应适量减少氮肥施用量。     

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.
