In recent years, distance education based on network environment has made great progress in China. The combination of network technology and teaching activities has brought new enlightenment to the education field. Under this background, this paper designs the distance teaching platform of network English course for communication engineering specialty, optimizes the design function of network English course platform, analyzes the common forms of the network English Course Teaching of communication engineering specialty and the new requirements of new forms for Distance English teachers, and probes into how to improve the teaching water of network English course teachers of communication engineering specialty In order to promote the further development and popularization of Distance English education.

Gender differences in science and engineering (S&E) have been studied in various countries. Most of these studies find that women are underrepresented in the S&E workforce and publish less than their male peers. The factors that contribute to gender differences in experience and performance in S&E careers can vary from one country to another, yet they remain underexplored. This paper is among the first to systematically compare gender differences in the publication productivity of academic scientists and engineers with doctoral degrees in the U.S. and China. Findings from negative binomial regressions show that women publish less than their male counterparts in science but not in engineering in the U.S. In China, women do not differ from men in publication productivity in science but publish more than their male counterparts in engineering. In addition, we find that some background variables affect men's and women's publication productivity differently. The findings are analyzed in the context of the different cultures of the two fields (science vs. engineering) and of the two countries (the U.S. and China). Limitations and policy implications are also discussed. [ABSTRACT FROM AUTHOR]

True 3D solid modeling of complex geologic bodies still face many difficulties. In this paper, a new technique of true 3D solid modeling is addressed, which incorporates the application of 2D&3D interactive aided section technology to revise scatter point aggregates, the means of two-body 3D data structure (improved B-rep 3D solid data structure) to organize data and the usage of vector shear technology for modeling. Based on such techniques, a true 3D solid model of a large hydropower engineering project in southern China was built to serve as intuitive platform for engineering survey, design, and construction. In the light of its wide application to many projects, it can be considered as a reasonable and effective method for 3D modeling of complex geologic bodies. [ABSTRACT FROM AUTHOR]

In hydrosystem engineering design and analysis, temporal pattern for rainfall events of interest is often required. In this paper, statistical cluster analysis of dimensionless rainfall pattern is applied to identify representative temporal rainfall patterns typically occurred in Hong Kong Territory. For purpose of selecting an appropriate rainfall pattern in engineering applications, factors affecting the occurrence of different rainfall patterns are examined by statistical contingency tables analysis through which the inter-dependence of the occurrence frequency of rainfall patterns with respect to geographical location, rainfall duration and depth, and seasonality is investigated. Furthermore, due to inherent variability of rainfall mass curves or hyetographs within each classified rainfall pattern, a practical procedure to probabilistically generate plausible rainfall patterns is described. The procedure preserves the inherent stochastic features of random dimensionless rainfall hyetograph ordinates, which in general are correlated non-normal multivariate compositional variables.
