NaCl胁迫对不同番茄品种幼苗及果实的影响     

鲍维巨  方巍  张琪晓  吴菊  杨飞 《河南职业技术师范学院学报》2011,(4):12-14

研究了NaCl胁迫对5个不同番茄品种的幼苗生长、果实可溶性糖含量及产量的影响.结果表明,盐胁迫抑制了番茄幼苗植株的生长,降低了幼苗的单株鲜重,减少了果实产量,但可以提高果实可溶性糖含量.同一盐胁迫条件下,不同番茄品种性状存在显著差异.  相似文献   

论教育宽容与创新人才培养     

田友谊  邱月 《天津师范大学学报(基础教育版)》2011,(4):7-10

教育宽容是在平等、理解、尊重的基础上,对教育及教育过程中的人与事给予一定限度的包容。然而,当前教育存在的不宽容,妨碍了创新人才的培养。因此,我们需要以教育宽容滋养创新人才成长的环境。  相似文献

深圳大鹏澳断裂构造及其对库坝区水文工程地质条件的影响     

黄玉昆  陈国能  王建华  赵不亿  夏法 《中山大学学报论丛》1992,(1)

本文从断裂构造及其活动性分析入手,结合地形、岩性和水文地质条件,讨论了库区蓄水后可能产生的坝基渗漏及绕坝渗漏问题。库区发育了NNW、NW、NE及NEE向几组断裂,但它们的大多数为压性或压扭性断裂、断面闭合、构造岩硅化甚强、致密坚硬、整体性良好。而张性断裂又多被后期岩脉充填,且与初选坝址平行分布,有利于防止库区内外水体的沟通。同时库区的所有断裂均未见其切割全新统地层。同位素测年资料表明,库区几条主要断裂的最后一次活动时间发生在晚更新世初期,目前属于不活动断裂。基于各方面的分析结果认为,库区水体向外渗漏或相邻海域海水向库区灌入的可能性较小。  相似文献   

论证券虚假陈述民事赔偿制度的缺陷与完善     

张卫国 《衡阳师范学院学报》2006,27(2):107-110

证券虚假陈述民事赔偿责任是信息披露义务人违反信息披露义务而承担的特殊侵权责任,适用证券侵权行为的一般理论。我国证券立法在虚假陈述民事赔偿责任的主体、归责原则、因果关系、损害赔偿范围等实体法律制度上存在缺陷,有待进一步的完善。  相似文献

论幼儿园在幼儿伤害事故中的责任归结     

彭茜 《西南师范大学学报(人文社会科学版)》2007,33(3):78-81

幼儿园对幼儿的教育、管理和保护职责不是基于《民法通则》设置的监护制度，而是源于带有公法性质的《教育法》、《未成年人保护法》等法律的规定，幼儿园与幼儿之间的法律关系是一种教育管理法律关系。幼儿伤害事故分为过错事故和意外事故，在过错事故中，幼儿园按照过错责任原则归责，但是应采用举证责任倒置的方式，在意外事故中，幼儿园不需承担法律责任，解决意外事故的真正出路在于幼儿园参加责任保险和幼儿参加人身伤害保险。  相似文献   

A comparison of Waldorf and non-Waldorf student-teachers’ social-emotional competencies: can arts engagement explain differences?     

Philipp Martzog  Guido Pollak 《师资教育杂志》2016,42(1):66-79

Teachers are confronted with complex and unexpected classroom situations that not only demand knowledge but also social–emotional competencies. Consequently, researchers have tried to identify conditions that support the development of relevant abilities in this domain. This study examined the frequently stated, but not yet empirically investigated, idea of immersion in the arts as a facilitator of aspects of empathy and tolerance of ambiguity (ToA). The paper compares Waldorf student-teachers who are strongly immersed in arts activities in their training with non-Waldorf student-teachers who do not participate in the arts on the constructs of empathy and ToA. Results indicated higher scores in the Waldorf group on both emotional and cognitive dimensions of the empathy construct and marginally higher scores on ToA. The results of this study and subsequent discussion suggest a new perspective on the relation between arts engagement and the specific domain of social–emotional competencies.  相似文献   

Fuzzy Comprehensive Assessment Method to Determine Tectonic Stress Patterns     

张海  戚蓝  郝彩哲  郭磊 《天津大学学报(英文版)》2007,13(6):462-468

The tectonic stress patterns were determined by a fuzzy comprehensive assessment method. Data of in-situ survey and fault information were utilized in the method. First, by making pressure and tension in the directions of along-river, cross-river, shear clockwise, and shear counterclockwise , 26 types of tectonic stress patterns were presented. And the stress vector of each pattern was obtained with FE software by taking unit displacement as boundary load. Then, by taking the 26 types of tectonic stress patterns as index set and 3 main stresses as factor set and choosing various operators, comparison of directions of computational stress vector and survey stress vector was made and the most possible tectonic stress pattern was obtained. Taking the 26 types of tectonic stress patterns as index set and strike angle as factor set, comparison of relationships between formation of fault and tectonic stress was made,and the tectonic stress patterns were assessed with known fault information. By summarizing the above assessment results, the most impossible tectonic stress pattern was obtained . Finally an engineering case was quoted to validate that the method is more feasible and reliable than traditional empirical method.  相似文献
