聚乙烯醇侧链液晶的结构与液晶性研究

研究了聚乙烯醇侧链液晶主链分子量和液晶基元等结构因素对其液晶性的影响，结果表明随着聚合物的分子量增加，导致复合物清亮点温度下降。但是在液晶主链尚未被液晶基元饱和之前，随着液晶基元相对主链摩尔比的增加，样品形成较为完善的氢键结构。     

Dialogue as the interplay of otherness and shared humanity.

Presents a reply by B. Fowers and B. Davidov to Islam's comments (see record 2007-14606-019) regarding their article (see record 2006-11202-002). Islam noted that virtues are often presented as universally valid character strengths, yet formulations of virtues are always embedded in a particular cultural context, a point we took pains to make in our article. We focus our response on Islam's important suggestion that this tension between universal human characteristics and the particulars of cultural context is indissoluble. Whereas he suggested this tension leads to contradiction and paradox, we see it as a fertile dialectic. The virtue of openness to the other is also subject to the same tension of abstract formulation and particular application. Although we formulated this virtue in a very general way, any instantiation of it would be shaped by the particulars of the cultural context and the situation in which it is exercised. We introduced the concept of dialogue because it is constituted not only by differences between individuals or groups but even more fundamentally by the dialectical relationship between those differences in cultural particularities and the universal human capacities for reason, curiosity, and social engagement, among others. Dialogue acknowledges the indissoluble otherness one finds in those culturally different from oneself, and yet real interchange can only occur because participants in dialogue exercise the cognitive flexibility characteristic of human beings and recognize a shared humanity with the other.

多灰度级显示器上的曲线绘制

光栅扫描显示器的屏幕是由位置固定的，离散的象素点所组成的，因而在其上生成的曲线只能是实际曲线的某种近似表示，并不是很美观的，例如有曲线的阶梯效应及曲线亮度不均度等问题，该文说明利用多灰度光栅显露器可以在一定程度上解决这些问题，并且用给出的主些算法绘制曲线时，可以较好地解决上述问题，这些算法在动画制作中也可有典型的应用。     

特征提取在硅内部微/纳米级体缺陷检测中的应用

提出了一种利用特征提取来对硅中微/纳米级体缺陷的激光散射图样进行分析,以获得缺陷大小信息的分析方法.给出了该方法中第一特征值和第二特征值的定义,指出通过所提出的第一特征值及第二特征值即可迅速地判断出缺陷的大小量级所在.这种分析方法具有分析速度快,在体缺陷小于1μm时分辨率高,且可使系统实现自动化等优点.     

从细线化汉字图像生成任意倍率汉字

本文提出了一种对汉字作任意倍率放缩的算法。该算法先对印刷体汉字作细线化处理，抽取笔划特征点。然后，分割和提取笔划。任意倍率汉字生成是通过变换函数。改变特征点位置，再附加原探察到的笔划修饰来实现的。实验表明本算法是有效的。     

扭杆弹簧的波动传递特性分析

建立了扭杆弹簧的波动方程，提出求解扭杆弹簧传递特性的方法，并推导出弹性波在扭杆弹簧中的传递速度，对沿弹簧传播的位移、速度、应力、应变和作用力的传递特性进行了探讨。分析了扭杆弹簧弹性单波的求解方法及波动干涉问题。推导了弹簧的波阻公式，为扭杆弹簧的波动理论建模及实际应用提供参考。     

Remarks on different reviews of Chinese character recognition

This paper gives an introduction and remarks on two review papers for Chinese character recognition. One review is made by Chinese authors, another is from American scientists. They investigate Chinese character from different language environments; they do the research from different points of view. Thus, a more comprehensive view on Chinese character recognition, which is an important branch of pattern recognition, can be provided to the readers. Meantime, one article pays attention to online process, and other paper deals with offline recognition, which complement each other. The author is the Associate Editor-in-Chief of Frontiers of Computer Science in China
