Rats in model control group were treated with distilled water while those in silibinin group were treated with 100 mg/kg silibinin. Meanwhile, 100 mL/L ethanol and hyperalimentation feed were given for 4 weeks. After animals were killed, TG, SOD, GSH and MDA levels were measured with liver suspension.

In this thesis,the voltage stability boundary is the combined boundary which correspond to Saddle-node bifurcations and Hopf bifurcations.The closest Hopf bifurcation point is found through the proposed iterative method under the assumption that the Hopf hypersurface is continuous and convex.
因此在本论文中,在多维参数空间下,将稳定边界推广到鞍点和Hopf分岔点构成的混合稳定边界,探索性寻求Hopf分岔超平面的法向量,采用迭代算法求取系统发生最近振荡型电压失稳的负荷增长方式。

Holding: The owner of the property on which buried money which is found embedded in the soil under circumstances that do not support the idea that the money was lost due to neglect, carelessness or inadvertence, but rather which circumstances suggest that the original owner intended to return to claim the money, has the presumed right to possess the found money against all but the original owner.
裁决:当这些钱是由于其主人故意埋在那里并有意图回来取,而不是由于疏忽、大意、或不经心丢在那里的情况下,埋藏地的产权所有者对这笔钱应该比其它任何人(这笔钱原来的真正主人除外)更有理由拥有所有权。

Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.

The computing plots of the solutions from the two methods were inconsistent under the specified boundary-initial conditions, which stirred up the debate of the effectiveness of Maxwell's equations in lossy medium. It is found that the differences between the two numerical curves can be viewed as the Gibbs phenomenon caused by cutting off the high frequency components in computing the infinite integral of the numerical curve of Harmuth's solution.
通过比较两种解析解的数值曲线得出:两者的差异在于求解Harmuth解的数值曲线时,采取无穷积分的高频截断近似产生了吉布斯现象;在计算Harmuth解的数值曲线时不断增大积分上限,其数值曲线的振荡不断向不连续点处收缩,而且衰减加快,因此在求解Harmuth解的数值曲线时,若积分区间取为理想无限大,则可以预见相同计算精度下两种方法的电场解的数值曲线是一致的。
