抗氧化石墨材料的实验研究

用一种新工艺——泥浆凝胶工艺制备了石墨材料抗氧化梯度膜，通过初级泥浆涂层和合理的实验参数控制，生成了致密的ＳｉＣ涂层。通过Ｘ射线衍射对涂层进行晶相分析，用扫描电镜分析涂层的成分，证实涂层中ＳｉＣ浓度呈梯度分布，因而缓和了涂层与基体间的热应力。氧化实验表明样品在１０００℃下氧化３００ｈ、１４００℃２００ｈ以及１６００℃、２０ｈ样品质量没有任何损失。１４００℃下经２０个热循环试验后样品完好无损

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.     

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。
