The calculated double differential cross section of the new model is compared with experimental data and previous SCDW calculations with single particle model. The calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi-elastic scattering angle. The agreement with experimental data is much improved.

Glycyrihizic acid can cause the polarigraphic catalytic wave of oxygen. GA scavenging superoxide ion is demonstrated chemically by the catalytic wave at molecular lever.

本文报道的甘草酸及其皂甙类衍生物存在下的氧极谱催化波，从分子水平研究了GA清除超氧离子自由基〓的化学作用机制，证实清除〓的活性基团是GA分子中与C＝O基共轭的C＝C双键，并非-OH基，纠正了文献观点。

To pay attention to carry out effective cardiopulmonary resuscitation, hemostasis by compression and deep vein intubation rapidly in the initial stage of emergency. The carotid shunt tube plays an important role in severe carotid injury and re-establishment process. We use external jugular vein to transplant and re-establish,which are rung with artificial blood vessels for the long distance carotid injury and achieved the best result. We expose as fully as possible for the hepatic venae and the posthepatic post caval injury,and adopt effective methods to stop bleeding and repair. The application of blood shunt pump could raise the success rate for those severe patients. The self-double vastransplantation with both ends being all trousers-style one opening solve some problems such as there are no suitable caliber self-transplantation blood vessels and the artificial blood vessels are easy to occur obliteration for long-term and so on for the great or middle blood vessels.We use improved Fogarty duct and anterograde intubation to eliminate thrombus could eliminate thrombus effectively and avoid accessory injury for the deep vein injury and extensive thrombosis.
