Most casing damages in Zhongyuan oilfield take place in the salt bed formations, and this has remained a problem that seriously threatens oil and gas production for long time. Causes of casing damages were investigated, and a series of measures in casing design have been adopted accordingly, but with unsatisfactory results.

Also being with the metamorphic crystalline basement formed later and suffered the stronger tectonic event and the material composition reforming, being composed of the material with low density and existing the relatively weak intrinsic mechanical system, Huaxia massif was affected by the various tectonic movement in the later period, the layers inside the lithosphere interacted under action of the tectonic force, this led to the material composition and the structure regulated and changed constantly by the magmatism in the crust, underplating and faulting and folding, therefore, the ability to resist the deformation decreased with the every variation.

华夏地块变质结晶基底形成时代晚，并遭受更多更强构造变动与物质组分的改造使之物质组成密度较小，岩石圈先期固有的力学结构系统相对较弱，尤其是后期的地球大系统的历次构造运动都对其施加影响，构造动力作用下引起内部圈层间相互发生作用，导致内部物质成分、结构形态通过壳内岩浆活动、地幔底侵作用、断裂褶皱等不断的调整重组重建而变化，其每一次调整变化，都使其总体抵抗变形能力进一步降低。

Influence of the antioxidants vitamin E and idebenone on retinal cell injury mediated by chemical ischemia, hypoglycemia, or oxidative stressRego A, SantosM, Oliveira C.. Free Radic. Biol. Med, 1999, 26: 1405 - 1417Abstract:A role for the antioxidants vitamin E and idebenone in decreasing retinal cell injury, after metabolic inhibition induced by chemical ischemia and hypoglycemia, was investigated and compared with oxidative stress conditions.

对由于化学贫血与低血糖所引起的代谢抑制后，抗氧化剂维生素E与艾地苯醌视网膜细胞受损所引起的作用进行了研究，同时并与氧化应激情况进行了对比，对氧化物维生素E(20 microM)和艾地苯醌(10 microM)进行先期培养可以在氧化应激或低血糖后防止视网膜细胞受损，而对上述二种抗氧化剂给予预先培养后带来的保护作用则有所减低。
