疾病叙事构成了《红楼梦》重要的部分,兼具审美意义和叙事功能。本文从身份、社会、情节三个方面讨论了疾病对于林黛玉和薛宝钗的不同意义。对林黛玉而言,疾病是认识社会的工具,是避风港和内心情感的宣泄。对薛宝钗而言,疾病和药是彰显社会地位的符号、一种社会资本。小说对二人疾病的刻画,反映了审美理想与伦理理想之间的张力,是儒家知识分子两难境地的写照。

Study of the aerostatic and aerodynamic stability of super long-span cable-stayed bridges

引用

Engineering Sciences 2014年第2期12卷 82-92页

作者： zhang xinjun Sun Hailing Zhejiang University of Technology

With the increase of span length, the bridge tends to be more flexible, and the wind stability be- comes an important problem for the design and construction of super long-span cable-stayed bridges. By taking a super long-span cable-stayed bridge with a main span of 1 400 m as example, the aerostatic and aerodynamic stability of the bridge are investigated by three-dimensional nonlinear aerostatic and aerodynamic stability analy- sis, and the results are compared with those of a suspension bridge with a main span of 1 385 m, and from the aspect of wind stability, the feasibility of using cable-stayed bridge in super long-span bridge with a main span above l 000 m is discussed. In addition, the influences of design parameters including the depth and width of the girder, the tower structure, the tower height-to-span ratio, the side-to-main span ratio, the auxiliary piers in the side span and the anchorage system of stay cables, etc on the aerostatic and aerodynamic stability of su- per long-span cable-stayed bridges are investigated numerically; the key design parameters are pointed out, and also their reasonable values are proposed.

A CHARACTERIZATION OF REALCOMPACT STONIAN SPACES X AND EXTENDED RIESZ HOMOMORPHISMS ON C~∞(X)

引用

Systems Science and Mathematical Sciences 2000年第2期13卷 159-163页

作者： XIONG Hongyun zhang xinjun (Department of Mathematics, Tianjin University, Tianjin 300072, China) 天津大学数学系天津 300072 天津大学数学系天津

Let X be a Stonian space and C∞(X) the Riesz space of all extended realvalued continuous functions from X into R-(=[-∞, +∞]). By Ω∞ we denote the collectionof all extended Riesz homomorphisms φ from C∞(X) into R with φ(Ix) = 1. In thispaper, we obtain that the Stonian space X is realcompact if and only if for every φ ∈Ω∞there exists a unique x ∈ X such that φ(f) = f(x) for any f ∈ C∞(X). When the Stonian space X is realcompact and Ω∞ is equipped with the topology induced by C∞(X), it is proved that Ω∞ is homeomorphic to X.
