ISBN: (纸本)9783037856093

Self-corrosion and galvanic corrosion of depleted uranium and 45 steel were studied by electrochemical analyzing technologies. Corrosion products were analyzed by Energy-dispersive spectroscopy （EDS）. The results showed that, in the 3.5wt.%NaCl solution, DU acted as anode with an accelerated corrosion rate, and 45 steel acted as cathode during the process of galvanic corrosion for DU/45 couple. The galvanic potential and current density of the DU/45 couple were around -770mV and 12.5μA/cm -2 , respectively.

作为纪录片研究领域不同于国内纪录片的重要研究对象,海外华人独立纪录片有着特定的内涵。将这一对象置于中华民族海外移民的背景下考察,可以发现,海外华人独立纪录片人通过族群记忆强化其移民身份,通过"中国题材"实现创作上的回归,而飘泊、离散的生活又将其推向事实上的无国、无家状态。海外华人独立纪录片人这种在东方与西方、母国与居住国之间的夹缝中生存的身份特征,为其纪录片赋予了超越国家与民族边界的全球视野。

OBJECTIVE: To evaluate the therapeutic effects of low-frequency phonophoresis with a Chinese herbal medicine(CHM) compared with sodium diclofenac(SD) for knee osteoarthritis(KOA).METHODS: In this double-blind, randomized, placebo-controlled trial, 100 KOA patients were assigned randomly to a placebo group, a CHM group,or SD group. Low-frequency phonophoresis was used to improve the efficiency of drug *** at rest [using a visual analog scale(VAS)], pain on movement(VAS), and range of motion(degrees) in the three groups were evaluated using the Western Ontario and Mc Master Universities Osteoarthritis Index(WOMACAI) scores. Safety assessments comprised emergency adverse events, aswell as laboratory tests of blood biochemistry, creatinine, blood urea nitrogen, alanine aminotransferase and aspartate ***: Significant improvements were found after treatment in all outcome measures except stiffness and range of motion in patients in the CHMP group and SDP group(P < 0.05). No significant differences in all outcome measures were found between the CHMP group and SDP ***: CHMP and SDP can show good therapeutic effects for KOA in terms of relieving pain and improving physical function.

L-arabinose is a newly developed low-caloric monosaccharide, which has many biomedical and health effects, especially intestinal sucrase inhibition effect. L-arabinose is mainly produced by chemical or enzymatic hydrolysis of hemicellulose. The taste of L-arabinose is quite similar to that of sucrose, with approximately 50% of the sweetness. As a functional additive, L-arabinose can be used in medical and pharmaceutical applications for the treatment of diseases such as diabetes, chronic constipation, mineral absorption disorder and secondary bile acid formation disorder. However, L-arabinose has not been widely used in functional foods due to high price and lack of publicity and guidance. A comprehensive review of L-arabinose physicochemical properties, production, applications field, market statue and development direction is presented in this paper.
