The gel dynamics experiments showed that the gel formation law was similar with the other polymer systems, which wasrelated with dense surface under the soft coagulating condition and the thickening gel; the square of gel thickness was linear with coagulation time. The qualitative analysis of the surface puckers of fibers spun from wet spinning and dry-jet wet spinning was made. The positions where the die swell appeared were not the same and the die swell appeared at the air gap where the fiber would markedly been elongated and vary little in the coagulant, thus the surface of fiber spun from dry-jet wet spinning was more smooth. The radial component concentration gradient was responsible for the radial structure of PAN fiber spun from dry-jet wet spinning. The thicker surface with microvoid structure of

对湿纺和干湿纺进行比较表层沟槽的产生进行定性分析,原因在于孔口胀大区域出现在不同位置,在干湿纺中,溶液的孔口胀大出现在空气层,并在该区完成大部分形变,进入凝固浴后形变很小,纤维表面较为光滑;干湿纺PAN纤维径向结构存在差异,这与丝条内组分由于双扩散进行导致径向上存在浓度差异直接相关;凝固强度较大的体系,可以获得厚度较大且孔结构尺寸较小的皮层;含较少缠结的PAN原液在纤维成形后截面很圆整,但原液缠结浓度增大时成形后圆整度下降;PAN纤维成形是一个远离平衡的过程,凝固作用缓和的体系可以使成形过程靠近平衡,可获得更大尺寸的孔洞结构;原液中少量的非溶剂添加剂显著改变纤维径向结构,可获得孔洞尺寸更小和更为均一的径向结构,这与径向浓度差异的减小、分相时间的集中相关;PAN原液的成形纤维表面依赖于凝固强度;由AFM对相近凝固条件下成形的PAN膜进下

Based on a quantitative analysis of radiolarian in 80 surface-sediment samples from the northern area of Okinawa Trough, this paper reported the species composition and faunal assemblages characteristic of radiolarian, expounded the distribution pattern of radiolarian abundance and diversity in surface sediments from this area. In this paper, a preliminary study on the relation of the distribution and abundance of radiolarian to environmental factors, such as chemical and physical properties of the overlying masses (sea-surface temperature, salinity, nutrients and primary productivity) and the type and composition of sea-bed sediments was made. The radiolarian data was evaluated using a Q-mode factor analysis to identify different faunal assemblages and their geographic distributions, then the relationship between radiolarian assemblages and distribution of water masses, hydrographic boundaries such as frontal systems was analyzed. A new radiolarian-based transfer function to estimate mean-annual sea surface temperature and seasonal range were examined to test its success in the study area.

本文对冲绳海槽北部80个表层沉积样品中的放射虫进行了系统鉴定和定量统计,研究了放射虫的种类组成与类群特征以及其丰度和分异度的分布;分析了海水温度、盐度、营养盐以及沉积物类型、成分等环境因素对放射虫分布的影响;采用Q-型因子分析,求得放射虫的属种和组合分布特征,探讨了放射虫组合与不同水团、海洋水文结构之间的关系;并对Pisias(1997)建立的估计表层海水年平均温度和其变化范围的放射虫转换函数在研究区的适用性做了检验。

In the special case of GLM—normal linear model with classical link function,we compare our methods with existing ones and our methods perform more excellently.Finally,sequential detection of structural changes is studied in nonparametric regression models o Based on Nadaraya-Watson estimator of regression function,we calculate the residual series and construct "residual cumulative sum process" with weight values of kernel estimator of "long-run average density function".

To explore the writers' self-consciousness, it is inevitable to analyze lots of works and to apply Chinese and Western psychoanalytic theories. I will present the harmony of the writers and the birds' images. Through the birds' narration of their feelings, the writers skillfully communicate the grief and the resentfulness of human nature. Also, I will discuss how mankind transcends the melancholy by reading the articles.

至於探讨的面向有三个,第一是「互诉关怀」,说明对於对方的思念、祝福与慰勉;第二是「唱和争胜」,经由唱和的过程,禽鸟所关涉的旨趣不仅彰显,彼此的感情与写作也有加分效果;第三则是「干谒求职」,这对唐人而言其实是司空见惯的,而禽鸟在这当中所扮演的当然就是作家自己;虽然对於禽鸟选择各有巧思,但都是极力推销的手法。
