绿豆幼苗发育初期叶绿素生物合成的研究

为了探讨被子植物幼苗发育初期Chl生物合成和调控机制,本文采用不同波长的光照和抗生素处理,分析了光照诱导绿豆黄花幼苗发育初期Chl含量的变化和抗生素对Chl生物合成的影响.结果表明：绿豆黄化幼苗在光照最初4 h,单色光有利于Chl生物合成;光照4 h后,单色光不利于Chl生物合成;同时单色光能够诱导提早Chl b生物合成,BL的作用大于RL1和RL2;脉冲光可以诱导Chl生物合成;抗生素实验显示,在光照2 h内,Chl生物合成过程不受质体和细胞核的调控;光照2 h以后,细胞核对Chl 生物合成有明显的调控作用,光照12 h后叶绿体的发育对Chl生物合成有明显的作用.本实验从亚细胞器水平探讨了绿豆幼苗发育过程Chl生物合成的可能调控机制.     

绵羊泰勒虫病的诊断与防治

对河南新乡市某羊场患病羊进行临床检查、病理剖检、血液染色镜检,并对泰勒虫和蜱进行形态学观察和虫种鉴定.结果表明,小羊红细胞染虫率为58％,大羊为25％.虫体和蜱经鉴定分别为泰勒虫及长角血蜱,确诊该羊场疾病是由长角血蜱传播的泰勒虫感染引起的,应用血虫净治疗及敌百虫灭蜱,疫情可得到控制.     

教育公平视角下城乡义务教育非均衡性分析

在将教育公平动态地划分为起点公平、过程公平与结果公平的基础上,将义务教育均衡划分为起点均衡、过程均衡与结果均衡。城乡义务教育起点不均衡,主要是教育机会与投入经费的非均衡;城乡义务教育过程非均衡,着重表现为办学条件与师资力量的非均衡;城乡义务教育结果非均衡,主要体现在升学率与学习能力的非均衡之上。为了促进城乡义务教育均衡发展,应该树立科学的均衡观;加快消除城乡二元结构;明确各级政府责任,实现投资主体上移而管理主体下移。     

Mechanism and implementation of directional quantum-behaved particle swarm optimization in OC-SVM

This paper uses the training of OC-SVM to analyze the mechanism of the Quantum-behaved particle swarm and develops a method of training OC-SVM based on the directional- QDPSO .The new position of the directional particle is calculated based on the current global best point(gBest), which identified the optimized direction conforms to Zoutendijk fastest decline method principle.In the initialization, the position of one particle is initialized according to SMO, which makes its position nearer to the global optimum solution. The boundary points of subjected plane are concerned as the initialized position of other particles, so as to make the searching area wider.The experiment result shows that the convergence and the generalization of D-QDPSO is good, the misrecognition of D-QDPSO is 0.12% lower than that of SMO, and the operating speed is 2 times faster than that of LPSO.     

Phylogeny of Limenitidinae Butterflies （Lepidoptera： Nymphalidae） Inferred from Mitochondrial Cytochrome Oxidase I Gene Sequences

The phylogenetic analyses of the subfamily Limenitidinae are performed based on 1471 bp of mtDNA cytochrome oxidase subunit I (C01) gene sequence data which were obtained from 21 individuals spanning 9 genera, along with those of 17species obtained from GenBank, using Apatura iris, Aglais urticae, and Polyura dolon as outgroup species. Although the transitions at the third codon positions of the COI data set were highly saturated, they were still retained for analysis as they contain the majority of the phylogenetic information, and thus, the maximum pasimony (MP) under different weighting schemes and maximum likelihood (ML) trees were reconstructed in this study. The results showed that within this subfamily, the results based on the COI gene sequences are approximately identical to the traditional classification results. However, the clustering of Lexias pardalis and Tanaecia julii within the genus Euthalia as well as the clustering of Phaedyma aspasia within the genus Neptis with weak support are different from that of the current classification scheme made by Chinese scholars. The genus Limenitis is splited into two subelusters in the trees constructed by using MP and ML methods. These results support one of the strongest hypotheses for the tribe relationships within Limenitidinae.

从长期施用多菌灵的葡萄园土壤中分离纯化得到一株对多菌灵降解效能高的菌株2-1。试验研究表明,该菌降解多菌灵的最适pH值为4.0~9.0,最适温度为25~30℃。该菌在培养温度30℃,pH7.0,摇床转速200 r/min条件下培养64 h,对多菌灵(200 mg/L)的降解率达100%。     

论高校学生伤害事故校方法律责任制度的完善

随着高校办学规模的扩大,学生伤害事故的发生日趋频繁。为此,有必要在对众多学生伤害事故分类研究的基础上,建立一个系统的事故防范与解决机制,借助社会保险、互助基金等手段,以化解学校管理面临的巨大压力,在尽最大可能缓解受伤害学生及家长痛苦的同时,维护学校及其他学生的基本利益,做到定纷止争,促进和谐校园建设。
