适用于混沌密钥分发的新误码协调方法

对于现有的密钥分发中的误码协调方法的复杂性和多次传输的问题，使用倒三角类坐标定位法来解决。将所得裸钥放置于下三角矩阵中，三边分别进行奇偶比较并互相传输计算结果，以达到定位错误比特位的目的。使用互注入光反馈激光器产生相关性高的混沌态来提取裸钥，通过该协调方法，最终可以达到10－8～10－10量级的误码率。通过该方法可以简单、有效地删除裸钥中的误码，满足现实通信对误码率的容忍度。

CHARACTERISTICS OF QUATERNARY AMMONIUM RESISTANT BACTERIA FROM A FINE PAPERMACHINE SYSTEM

To evaluate the biocide effect of quaternary ammonium chloride (QAC), a whitewater sample was taken from a fine papermachine headbox. By plate spreading method, 51 strains of facultative anaerobe were isolated morphologically. Then the strains were separately transferred to basal medium and were incubated before the beginning of log phase. To identify strains with different QAC resistance, 30-120 ppm of N-Alkyl-benzyl-dimethyl ammonium chloride were added to basal medium.Biocide effect was investigated by comparison of bacterial growth, which can be monitored by 600 nm light absorbance of basal medium suspension. Among 51 strains, only 2 strains can Survive for QAC concentration up to 120 ppm. API20E aud 16S rRNA gene sequencing technique were applied to identify two strains with highest (120 ppm)QAC resistance. One strain (HB22)was identified as Morganella morganii. HB22 can resist QAC concentration up to 150 ppm. HB22 is Gram-negative rod, motile with flagella, catalase positive, oxidase negative, Indole positive, H2S production negative, facultative anaerobe. HB22 has optimum growth condition of 35℃ and pH 7.0.HB22 can catabolize only glucose and D (+)-Mannose.The other (HB45) was identified with high similarity among Pseudomonas cf. monteili or Pseudomonas mosselii or Pseudomonas putida. HB45 can resist QAC concentration up to 200 ppm.HB45 is Gram-negative rod, motile with flagella,catalase positive, oxidase negative, Indole negative,H2S production negative, aerobe. HB45 has optimum growth condition of 30℃ and pH 7.4. HB45 can catabolize L-Arabinose, L(+)-Rhanmose, D (+)-Mannose, Glucose, Glycerol, Lactose, Maltose,Raffmose, Xylose, Cellulose and Xylan. The implication of this work to paper industry is also discussed.     

浙江省农业现代化与农村经济发展的灰色关联分析

农业现代化是发展农村经济，提高农民收入的重要条件，本文运用灰色关联分析方法研究了浙江省农业现代化与农村经济发展的关系，通过研究，发现农业电气化水平对农村经济发展的影响最大，其次是机械化水平，而农田灌溉对农村经济发展的影响最小，最后根据灰色关联分析的结果，提出了对农业现代化建设的若干建议。

PIC系列单片机片内定时器实时时钟的实现

针对直接用单片机片内定时器作实时计时不准问题，本文提出了一种可以获取与秒成整数倍关系的定时器溢出信号的方法，同时克服定量溢出中信号被其它中断暂停所受的计时影响，实验表明，在4MHz晶振下，计时误差可控制在每天14s以下，本方法也适用于一般的单片机，在PIC87系列上的实验结果表明效果很好。
