利用热解气相色谱鉴别真假油气显示

由于钻井液添加剂对岩屑的污染，给识别真假油气显示造成了一定的难度。该介绍了一种利用热解气相色谱分析技术鉴别真假油气显示的方法。通过对27种添加剂检测分析，分别得出不同添加剂的色谱曲线特征，其中针对15种对岩屑影响较大的添加剂的曲线特征分析研究发现应用热蒸发烃、热解烃色谱曲线与添加剂的热解指纹谱图对比，可快速、准确的鉴别真假油气显示，多口井的实践表明，此方法对现场录井具有重要意义。此外，通过实验证实水洗法排除样品污染较差，利用扣除本底法可准确求得热蒸发烃、热解烃污染校正系数，是排除样品污染的较理想方法。

初探水市场

中国是一个水资源短缺的国家。现在我们面临三大问题：洪涝灾害、干旱缺水、水环境恶化。洪涝灾害，可以通过修建控制性水利工程、加固堤防等措施来解决，后两个问题，除了大力抓好节约和保护水资源外，更要搞好水资源的优化配置。而水资源的优化配置就是解决供需矛盾。供需关系的变化，带来水权关系的变化。那么研究水资源的所有权、使用权和水市场问题是摆在我们水利工作者面前的一个重要而又迫切的课题，这也是如何利用经济手段实现水资源优化配置问题。因此，在未来水务体制建设中引入市场机制已是大势所趋。　　建立水市场，是市场经…     

Pb（Fe2／3W1／3）O3的制备及其介电性能研究

本文采用半化学法，即硝酸铁代替传统氧化物混合法中的三氧化二铁与PbO和WO3浆料混合，经850℃，2h预烧，一步合成了钙钛矿单相的Pb(Fe2/3W1/3)O3(PFW)预烧粉体；再经870℃和2h烧结，得到了纯钙钛矿相的PFW陶瓷，其理论密度大于98%，在1kHz时的最大介电常数εmax为8000，高于二次合成法和传统氧化物法制备的PFW陶瓷，表明半化学法对制备PFW陶瓷是可行的。     

Isothermal Gas Forming of Mg Alloy AZ31 Sheet

There have been reports on sheet forming of Mg alloy in industry via the punch and die method;this paper is probably the first formal one for studying the sheet formability of AZ31 employing pressurized gas to press the sheet into a female die cavity at various elevated temperatures.The results indicate it is feasible to form a rectangular box via pressurized gas from extruded sheets of 0.5 and 1.7 mm thick.The formed box has 1:2 depth over width ratio,which should be large enough when dealing with realistic industrial sheet forming parts.Presently,forming a sheet of 0.5 mm thick is considered a technical challenge by industry,and it is conquered as demonstrated in this paper.Gas forming technique applied to Mg alloy is unprecedented and shows potential for industrial utilization.
