驳“司马迁‘心折长卿之至’”论

《史记·司马相如列传》是司马迁笔下一篇较为特殊的文章。作者的叙事较少,而传主的文赋却选录极多。前人认为这是由于子长极为喜爱相如文赋所致,但从全篇的行文结构、作者对司马相如的评价及该文与《屈原贾谊列传》比较阅读而言,实非如此。司马迁选录相如的文赋,并非是欣赏其中雍容华丽的辞章的表层形式,而是结构全文的需要,也是借他人之文抒发自己的政治主张;对于司马相如本人,司马迁在字里行间透露了中肯但并不褒扬的客观态度,并不是"心折长卿之至"一语所能道尽。     

初中化学解题推理思维的案例分析

在初中化学教学阶段,由于受年龄和身心发展的影响,学生思维的运作形式主要是具体形象的推理思维,包括演绎推理和归纳推理,本文结合具体的案例,从定性推理思维和定量推理思维两个方面加以分析。1 定性推理思维及其案例分析定性推理是确定研究对象具有某种属性的推理     

A learning-based method to detect and segment text from scene images

This paper proposes a learning-based method for text detection and text segmentation in natural scene images. First, the input image is decomposed into multiple connected-components (CCs) by Niblack clustering algorithm. Then all the CCs including text CCs and non-text CCs are verified on their text features by a 2-stage classification module, where most non-text CCs are discarded by an attentional cascade classifier and remaining CCs are further verified by an SVM. All the accepted CCs are output to result in text only binary image. Experiments with many images in different scenes showed satisfactory performance of our proposed method.

论不动产物权登记的效力

不动产物权登记是物权法中的一项重要制度,不动产物权登记的变动在不同立法体制下表现出差异。我国的法律应结合我国的实际,对不动立登记效力作出统一的规定,以便更好地维护产权交易安全。     

语文活动中创新和实践能力的培养

创新精神是民族进步的灵魂。面对世界科技飞速发展的挑战,我们必须把增强民族创新能力提到关系中华民族兴衰存亡的高度来认识。教育在培育民族创新精神和培养创造性人才方面,肩负着特殊的使命。语文是教育的基础学科,在实施素质教育、培养创造性人才上有着独特的不可替代的作用。把培养学生的创新意识和实践能力放在语文教学的重要位置上,使语文教育迈上一个新台阶。

In vitro remineralization of hybrid layers using biomimetic analogs

Resin-dentin bond degradation is a major cause of restoration failures. The major aim of the current study was to evaluate the impact of a remineralization medium on collagen matrices of hybrid layers of three different adhesive resins using nanotechnology methods. Coronal dentin surfaces were prepared from freshly extracted premolars and bonded to composite resin using three adhesive resins (FluoroBond II, Xeno-III-Bond, and iBond). From each tooth, two central slabs were selected for the study. The slabs used as controls were immersed in a simulated body fluid (SBF). The experimental slabs were immersed in a Portland cement-based remineralization medium that contained two biomimetic analogs (biomineralization medium (BRM)). Eight slabs per group were retrieved after 1, 2, 3, and 4 months, respectively and immersed in Rhodamine B for 24 h. Confocal laser scanning microscopy was used to evaluate the permeability of hybrid layers to Rhodamine B. Data were analyzed by analysis of variance (ANOVA) and Tukey’s honest significant difference (HSD) tests. After four months, all BRM specimens exhibited a significantly smaller fluorescent area than SBF specimens, indicating a remineralization of the hybrid layer (P≤0.05). A clinically applicable biomimetic remineralization delivery system could potentially slow down bond degradation.
