工程征地移民监测评价在万家寨引黄工程中的应用

万家寨引黄工程是世界银行（以下简称“世行”）贷款项目，《万家寨引黄工程总干线、南干线及联接段工程征地移民规划报告》于1996年10月世行政在式评估通过确认按世行移民导则要求独立的外部监督机构，对引黄工程征民移民规划实施进行监测评价，为此，山西省万家寨引黄工程总公司委托黄河水利委员会移民局担任此项工作，并得到了世行的认可，监测评价的目的是确保工程征地移民安置规划的实施，严格按照国家的有关法规、政策及世行4.30导则要求，监测评价工作从1997-2001年每年监测2次，并提交2次独立的监测评价报告，到目前已实施了4年。

位于准噶尔盆地腹部的陆梁油气田是准噶尔盆地的又一个亿吨级油气田。笔者运用地球化学方法分析了陆梁油气田石炭纪—早白垩世地层水的类型、平面和纵向分布特征，将其划分为3个水文地质旋回，第一旋回为石炭系—三叠系，为深层静止开放的滞流型水力系统；第二旋回为侏罗系八道湾组—西山窑组，为中层弱开放的压实驱动型水力系统；第三旋回为侏罗系头屯河组—白垩系，为浅层强开放的重力驱动型水力系统。第一、二水文地质旋回是油气生成和初次运移的有利时期，淋滤期前的一段时间是油气二次运移和成藏的较好时期，第三水文地质旋回是油气藏破坏及次生油气藏形成的时期。

一种测定深部岩体地应力的新方法——钻孔局部壁面应力全解除法

简要回顾了基于钻孔进行地应力测量的几种方法，并指出了这些方法自身存在的局限性。提出了一种测定深部岩体地应力的新方法-钻孔局部壁面应力全解除法。该方法的明显优点是，不需要套钻，而且在确定地应力的主值及其方向时也不需要作任何假定。从理论上讲，该方法将不受测量深度的限制，对于深钻孔是普遍适用的，这将为大陆科学钻探计划中深部岩体地应力测量提供一种新途径。     

Effects of EGb 761 on nitric oxide and oxygen free radicals, myocardial damage and arrhythmia in ischemia-reperfusion injury in vivo

The cardioprotective effects of EGb 761 on the release of nitric oxide (NO), the concentration of serum thiobarbituric acid reaction substance (TBARS), the activity of creatine kinase (CK) and the incidence of ventricular arrhythmias were investigated in myocardial ischemia-reperfusion injury in vivo. Using sodium nitrite (NaNO2) as standard source of nitric oxide (NO), we compared the correlation coefficients of the three measuring methods used currently in the determination of NOFe2+(DETC)2 complex with that of the measuring method suggested in this study. The result showed that measuring the whole height of three splitting signals is the best linear correlation to the concentration of NO comparing with other methods in this system. Using this method, we observed the effects of EGb 761 on NOFe2+(DETC)2 complex in myocardial ischemia-reperfusion injury in vivo. The hearts of the Wistar rats were subjected to 30 min of ischemia and 10 min of reperfusion in vivo. Different doses of EGb 761 (25, 50, 100, 200 mg/kg i.p.), superoxide dismutase (SOD, 10(4) U/kg), l-arginine (50 mg/kg i.p.) and nitric oxide synthase (NOS) inhibitor NG-nitro-l-arginine (NNA, 50 mg/kg i.p.) were administered to the ischemia-reperfusion rats. EGb 761 under the dose of 100 mg/kg increased the signal intensity of NOFe2+(DETC)2 complex, while EGb 761 at 200 mg/kg showed an effect of decreasing the signal intensity of NOFe2+(DETC)2 complex. EGb 761 inhibited the formation of TBARS, the release of CK, and mitigated the incidence of ventricular arrhythmias in a dose dependent way. Both l-arginine and SOD increased the signal intensity of NOFe2+(DETC)2 complex and inhibited the formation of TBARS, the leakage of CK and the incidence of ventricular arrhythmia. NNA not only had no protective effects on myocardial injury, but also increased the incidence of reperfusion-induced arrhythmia. In conclusion, EGb 761 has cardiovascular protective effects by means of adjusting the level of NO and inhibiting oxygen free radicals induced lipid peroxidation in myocardial ischemia-reperfusion injury in vivo.     

A state-space approach to parameterization of stabilizingcontrollers for nonlinear systems

A state-space approach to the Youla parameterization of stabilizing controllers for linear and nonlinear systems is suggested. The stabilizing controllers (or a class of stabilizing controllers for nonlinear systems) are characterized as fractional transformations of stable parameters. The main idea behind this approach is to decompose the output feedback stabilization problem into state feedback and state estimation problems. The parameterized output feedback controllers have separation structures. This machinery allows the parameterization of stabilizing controllers to be conducted directly in state space without using coprime factorization
