论英语课文教学中阅读能力的培养

阅读是掌握语言知识、打好语言基础、获取信息的重要渠道。阅读能力是大部分大学生今后工作所需的主要语言技能，在大学英语教学中要始终注重阅读能力的培养。从语言学习的规律来看，英语应用能力的提高是建立在大量的语言输入，尤其是大量阅读的基础之上的。近年来，随着考试命题要求的不断提高，考查学生阅读能力的试题比重越来越大，阅读难度有所增加。因此，如何培养和提高肇生阅读能力，显得尤为重要。     

海南岛西北岸礁坪堆积物的粒度参数与分布特征

松散堆积物的粒度成分及分布规律与沉积环境息息相关,于潮间带以平台地形出现的现代礁坪对其上的松散堆积物的沉积过程施于深刻的影响.本文就海南岛西北岸邻昌、大铲离岸礁和小铲近岸滩礁礁坪上的松散堆积物的粒度参数和粒度分布的若干特征,探讨它们与沉积环境的关系.     

透明电解槽研究铝在冰晶石—氧化铝熔液中的溶解

本文用透明电解槽对金属铝在冰晶石一氧化铝熔液中的溶解及阳极效应进行了直接的观察,铝溶解时先放出大量细小的气泡,然后泛起蓝褐色的金属雾,一定时间后铝为一黑褐色结壳,所包裹熔液重新变清,电解后,金属雾很快消失,一旦停止电解,金属雾便重新从铝液上泛起,阳极效应时阳极上产生一股气流喷向阴极,认为铝的溶解形式主要是电化学溶解,阴极极化(电解)可以使铝的溶解得到抑制,阳极喷射则是由于阳极气体膜电离所致,使得电流效率降低。

On the Hejek-Renyi Inequality

In this paper we give an elementary and unified proof of the Hajek-Renyi inequality, and get a general version of this inequality which not only covers the all known results but also derives some new results.     

Distributed modeling of the beginning and ending dates and durations of limited temperatures over the rugged terrain of Chongqing

A physically based empirical model was established for the beginning and ending dates (BED) of limited temperatures.Data used were daily mean temperatures from 34 conventional stations in the Chongqing region,measured from 1961 to 2000.Using this model in combination with the distributed modeling results of monthly mean temperatures,we developed a method for creating a distributed simulation of the BED and durations of limited temperatures in the rugged terrain of Chongqing.Spatial distribution maps were generated at a resolution of 100×100 m for the BED and durations of the limited temperatures of 0,10,15 and 20.Simulations suggest that the distributed model is able to successfully reveal the macroscopic trends and local distributions.For the modeled BED,the mean absolute bias error is 0.6-2.4 d.Cross-validation and case-year tests show mean absolute bias errors of 1.3-2.8 d and 0.7-2.5 d,respectively.Comparison shows that the simulation results are consistent with the field investigations.This implies that the simulations are as good as observations,thus providing a viable technique for simulating mountainous heat resources using conventional meteorological data.     

大学生价值取向与行为规范研究：现状、问题与对策

通过对近年来大学生价值取向与行为规范研究的归纳和总结，阐述和提出了大学生价值取向与行为规范研究的现状、问题与对策。认为研究现状是静态性的研究多于动态性的研究，特征性的研究多于规律性的研誊，研究素材中想象的问题多于实际发生的事例；遇到的问题是社会主流意识影响与非主流意识影响的博弈日益加剧，有约束环境与相对无约束环境的影响差别明显，知识层面教育与思想道德层面教育不协调。     

One Way to Eliminate Corruption-Educating People——Brief Introduction on Bid

This article,according to the author's working experience in a hydropewer project,briefly introducessome basic knowledge about bidding process and sample contract document.It is aiming at giving a commonknowledge to the students who will be involved in work relating to bid after their graduation in the college.It ishoped that this kind of knowledge can help people properly use funds for a project and thus corruption can beminimized.

民国时期镇江城市建设及其教训

民国时期镇江一度是江苏省的省会，曾对城厢道路、公益性设施及园林绿化等方面作过规划与建设，取得一些成效。后因日军侵华及国民常政府腐败，致原订省会建设计划多半未能实现。重温这段历史，对今天的镇江城市建设或可引以为鉴。
