在谈到影响英语教学效率的因素时，人们常常会想到教师的素质和学生的智力与非智力因素，但事实上还有诸多因素影响着英语教学的效率，诸如英语教学进度，教材的质地，学习时间的分配，评价方式，听说读写译的顺序、程度等。这些因素看似隐性，但对英语教学的作用却是显性的。所以，对这些因素进行适当调控是提高英语教学效率的有力保障。 相似文献

参加过钓鱼大赛的人都知道,钓位的好坏让你服了,不服不行！抽到好钓位好运自然来,相反是一点辙都没有,这话乍一听多有过头其实一点也不偏离实际,引用朱德禄的话讲:“现在青年钓手高手很 相似文献

刑事附带民事诉讼对于有效维护公民、国家、集体财产不受犯罪侵犯、维护其合法权益，提高司法机关办案效率，具有重要意义。但长期以来，由于我国现行法律规定并不完备，附带民事诉讼的相关制度未能充分发挥其保障附带民事诉讼原告人合法权益的作用。从附带民事诉讼中的诉讼保全和精神损害赔偿两个方面来探讨如何更加有效地保障附带民事诉讼原告人合法权益。 相似文献

珠江三角洲稻区鼠类群落结构及演替研究 总被引：7，自引：0，他引：7
1985～1993年进行了鼠类群落组成、种间关系及群落演券规律研究．结果表明，珠江三角洲稻区的鼠类数量组成以小家鼠、黄毛鼠和板齿鼠为主，可划分两类群落类型．其鼠类数量组成均有极显著的季节波动，板齿鼠和黄毛鼠的生物g在A群落及B群落中均占绝大部分．板齿鼠与黄毛鼠的食性、栖息空间及活动节律相近．种间竞争较大．由于化学灭鼠及农田作物布局的改变．导致鼠类群落组成发生了显著的变动． 相似文献

Property path is the latest navigational extension of the standard query language SPARQL 1.1 for the Semantic Web.However,in the existing SPARQL query systems which support property path,the query efficiency is very low and does not support reasoning.This paper proposes a new existential semantics which has polynomial-time evaluation complexity and an equivalent relationship with the current semantics,and transforms the property path expressions to the extended nested regular expressions based on the existential semantics and proves the semantic equivalence after the transformation considering the RDFS semantics.The property path query engine is achieved by implementing the nested regular expressions algorithm and the transformation rules from the property path expressions to the nested regular expressions,which maintains the syntax simplicity of property path and the goal-oriented polynomial-time reasoning to avoid computing the RDF graph closure.The experiment results not only show the characteristics of query engine based on the existential semantics in efficiency and reasoning,but also further validate the equivalence between the results based on current semantics and those based on the existential semantics for property path after the removal of duplicate values. 相似文献

In order to evaluate all attack paths in a threat tree,based on threat modeling theory,a weight distribution algorithm of the root node in a threat tree is designed,which computes threat coefficients of leaf nodes in two ways including threat occurring possibility and the degree of damage.Besides,an algorithm of searching attack path was also obtained in accordence with its definition.Finally,an attack path evaluation system was implemented which can output the threat coefficients of the leaf nodes in a target threat tree,the weight distribution information,and the attack paths.An example threat tree is given to verify the effectiveness of the algorithms. 相似文献
