周必大评苏的方法问题

周必大作为南宋前期重要的政治家,在当时朝野推崇苏学的政治背景和学术氛围下,十分关注与敬重苏轼。他采用考证、点评、辨析等方法,对苏轼的生平事迹、道德文章进行了深入考察和客观评价,体现了作者独特的人品风范与学问见识。文章对这些问题进行了系统梳理和总结概括。周必大提供的不少今人未见的苏轼佚文线索,表明苏轼研究的文献收集整理等基础工作,还需要继续努力进行。

传统农业区稻田多个物种共存对病虫草害的生态控制效应——以贵州省从江县为例

本文运用半试验与调查相结合的方法,以贵州省从江县传统农业地区的糯稻和杂交稻为例,研究了传统品种和现代品种在水稻单作(R)、稻-鱼(R-F)和稻-鱼-鸭(R-F-D)3种不同稻作方式下,稻田多个物种共存对稻田生态系统主要病虫草害及蜘蛛的影响。结果表明,就水稻品种而言,糯稻在3种稻作方式下的抑制杂草能力均优于杂交稻,糯稻田与杂交稻田的稻飞虱虫量、稻纵卷叶螟虫量以及蜘蛛量差异不显著,杂交稻在3种稻作方式下的抗稻瘟病能力显著高于糯稻。就稻作方式而言,R-F-D显著降低了田间杂草的发生密度,对稻田杂草鸭舌草(Monochoria vaginalis)、节节菜(Rotala indica)等的抑制效果达到100%,总体抑制效果显著优于其它的稻作方式;R-F-D系统的稻飞虱、稻纵卷叶螟虫量较水稻单作明显减少;R-F系统的蜘蛛数量最高;R-F-D系统的抗稻瘟病性最好。     

濒危植物巴东木莲花粉母细胞减数分裂观察

对巴东木莲Manglietia patungensis及其近缘种乳源木莲M. yuyuanensis的花粉母细胞减数分裂过程的基本特征进行了比较研究。乳源木莲与巴东木莲的染色体数目和核型相同,但不经任何人为因素诱导,它们之间在减数分裂过程中的染色体行为上有明显差异。(1)巴东木莲减数分裂中期I构型为0.30IV+18.33II+0.15I,与乳源木莲构型19II不同,巴东木莲可能存在同臂内倒位杂合子,染色体结构存在一定的杂合性。(2)后期I和后期II染色体行为异常现象发生频率明显不同。以后期II为例,乳源木莲减数分裂相中有迟滞染色体的细胞占8.8%,迟滞染色体不超过2个;巴东木莲有迟滞染色体等异常现象的细胞占29.2%,迟滞染色体最高达11个,还出现染色体碎裂成断片现象。巴东木莲减数分裂过程中染色体组表现出染色体结构杂合变异和迟滞染色体与染色体的断裂频率很高的异常现象在一定程度上可能影响了雄配子体的发育。     

Moral education and values education in curriculum reform in China

In the new curriculum reform in China, moral education and values education have been defined from the angles of the integrity and conformity of curriculum functions. Accordingly, a new education concept based on complete/integral curriculum functions is established. By discussing the essences of the curriculum, the basis of moral and values education, integrated curriculum setting in instruction structure, the presence of emotional and attitudinal goals in the subject standards, and teaching methods, this text points out that this curriculum reform looks to moral and values education in schools. The reform also emphasizes and will guarantee moral and values education in schools. Finally, the article recommends to elementary and secondary schools the studies on moral education in class conducted by the Research Institute of Moral Education of Nanjing Normal University, one of the Key Bases for Humanities and Social Sciences Research for the Ministry of Education. __________ Translated from Global Education, 2002:12

Some Effects of Teaching Designed to Promote Understanding of Racial Issues in Adolescence

Abstract:

Moral education must be based on universal religious values, such as equality and faith, if it expects to have an impact on character development The central objective of our moral education programme is co‐operation. To specify what is meant by co‐operation, three of its aspects ‐‐ courtesy, consultation and service ‐‐ are discussed. Methods of facilitating moral development fall into three categories: ground rules, modelling, and moral reasoning. These methods must be used jointly if they are to be effective. Releasing the potential of both the society and the individual constitutes the goal of moral education.

不同油莎豆品系块茎形成规律的比较研究

为揭示油莎豆块茎的形成规律,采用自然种植、定期采样观察等方法对三种不同油莎豆品系块茎的形成过程进行详细观测,结果表明：这三种油莎豆的分蘖数、匍匐茎形成时间、匍匐茎长度及直径、块茎开始膨大形成时间、每株形成块茎数量、块茎大小及形态、块茎在土壤中分布格局等性状存在显著差异,说明不同品系油莎豆的块茎形成特性不同,可为油莎豆的栽培和开发利用提供参考。
