对PBO-AS单丝实施拉伸，通过观察拉伸断裂后的单丝形态，分析单丝断裂强力同单丝微观结构的关系．通过显微镜观察发现，PBO断裂后的单丝微观结构发生变化．提出单丝本身结构和原纤化可能是导致这些结果的主要原因．     

楊廉夫名“楨”“禎”二字考

楊廉夫為元末明初的著名詩人、書法家,表字廉夫,其名維楨,亦作維禎。楊廉夫之名二字混用由來已久。《四庫全書總目提要》未對“楨”“禎”二字作考證,直以“楨”字》是。本文通過對歷代目志、石刻碑誌材料、楊廉夫法真蹟與印鑒題識以及方志材料等多個方面的考察,證實楊廉夫本名應作“楊維楨”,楊氏文集中“楨”“禎”混雜的現象,並非刊刻傳抄過程中形成的訛誤,而是始自楊廉夫本人對二字的有意混用。     

A theoretical model for mid-and low-latitude ionospheric electric fields in realistic geomagnetic fields

The geomagnetic fields, which play important roles in the ionospheric dynamo, can greatly affect the global distribution of ionospheric electric fields, currents and other ionospheric electrodynamics phenomena. In the study of ionospheric electrodynamics phenomena, such as the longitudinal variations of ionospheric electric fields, the non-dipolar component of the geomagnetic fields must be taken into account. In this paper, we deduce a theoretical electric field model for ionospheric dynamo at mid- and low-latitude which adopt a modified magnetic apex coordinates system. In the new electric field model, the geomagnetic fields can be calculated from either the IGRF model or the dipole field model, and the neutral winds and conductivities are calculated based on empirical models. Then the dynamo equation for the electric potential is finally solved in terms of the line-by-line iteration method, and the ionospheric electric fields and currents are derived from the calculated potential. Our model can reproduce the main features of the ionospheric electrodynamics processes, so it will be a useful tool for the investigation of the upper atmosphere and ionosphere.

A New Discipline of Science-The Study of Open Complex Giant System and Its Methodology

This paper introduces the conception of open complex giant system and the methodology for dealing with the system, with stress on its profound significance in development of science and technology. The authors conclude that the reductionism underlying the exact science is not suitable to open complex giant system, and the only feasible alternative is the meta-synthetic engineering from the qualitative to the quantitative.
