The orientation angle is an important parameter that reflects the structure of molecules at interfaces. In order to obtain this parameter, second order nonlinear spectroscopic techniques including second harmonic generation （SHG） and sum frequency generation-vibrational spec- troscopy （SFG-VS） have been successfully applied through analysis of the nonlinear signal from various polarizations. In some SHG and SFG-VS experiments, total internal reflection （TIR） configuration has been adopted to get enhanced signals. However, the reports on the detailed procedure of the polarization analysis and the calculation of the orientation angle of interracial molecules under TIR configuration are still very few. In this paper, we mea- sured the orientation angles of two molecules at the hexadecane-water interface under TIR and Non-TIR experimental configurations. The results measured from polarization analysis in TIR configuration consist with those obtained from Non-TIR configuration. This work demonstrates the feasibility and accuracy of polarization analysis in the determination of the orientation angle of molecules at the interfaces under TIR-SHG configuration.

Head smut of maize （Zea mays L.）, which was caused by Sporisorium reiliana, occurred in most of the maize growing areas of the world. The purpose of this study was to develop SCAR markers for map-based cloning of resistance genes and MAS. Two sets of BC3 progenies, one （BC3Q） derived from the cross Qi319 （resistance）×Huangzao 4 （susceptible）, the other （BC3M） from Mol7 （resistance）× Huangzao 4 （susceptible）, were generated. Huangzao 4 was the recurrent parent in both progenies. A combination of BSA （bulked segregant analysis） with AFLP （amplified fragment length polymorphism） method was applied to map the genes involving the resistance to S. reiliana, and corresponding resistant and susceptible bulks and their parental lines were used for screening polymorphic AFLP primer pairs. One fragment of PI3M61-152 was converted into SCAR （sequence charactered amplified fragment） marker S130. The marker was mapped at chromosome bin 2.09, the interval of a major QTL region previously reported to contribute to S. reiliana resistance. Furthermore, S130 was highly and facilitate map-based cloni associated with resistance to S. reiliana, and could be useful for marker-assisted selection ng of resistance genes.

Cerebral blood flow is strongly associated with brain function, and is the main symptom and diagnostic basis for a variety of encephalopathies. However, changes in cerebral blood flow after mild traumatic brain injury remain poorly understood. This study sought to observe changes in cerebral blood flow in different regions after mild traumatic brain injury using pulsed arterial spin labeling. Our results demonstrate maximal cerebral blood flow in gray matter and minimal in the white matter of patients with mild traumatic brain injury. At the acute and subacute stages, cerebral blood flow was reduced in the occipital lobe, parietal lobe, central region, subcutaneous region, and frontal lobe. Cerebral blood flow was restored at the chronic stage. At the acute, subacute, and chronic stages, changes in cerebral blood flow were not apparent in the insula. Cerebral blood flow in the temporal lobe and limbic lobe diminished at the acute and subacute stages, but was restored at the chronic stage. These findings suggest that pulsed arterial spin labeling can precisely measure cerebral blood flow in various brain regions, and may play a reference role in evaluating a patient＇s condition and judging prognosis after traumatic brain injury.

针对印染废水回用时水中有机物浓度、盐度和色度高等问题,以苏南某污水处理厂中试试验基地(70%以上为印染废水)二级生化出水为研究对象,对混凝沉淀-超滤(以下称组合工艺1)、BAC(生物活性炭滤池)-超滤(组合工艺2)和混凝沉淀-BAC-超滤(组合工艺3)3种工艺进行比较研究,系统考察其作为反渗透预处理技术的可行性.结果表明:组合工艺3对印染废水二级生化出水中CODCr、TCU(真色)及浊度的平均去除率分别为53.0%、49.2%和99.5%,UV254下降了50.0%,均高于其他2个组合工艺.对超滤膜表面污染阻力分布的测定可知,组合工艺3中不可逆污染造成膜污染的程度最轻.此外,3种组合工艺的出水通过反渗透装置后的平均脱盐率分别为98.0%、97.5%和98.2%.可见,针对该研究中涉及的二级生化出水,组合工艺3预处理工艺是反渗透预处理的最佳工艺.
