Melt-dripping is always a big chanllenge in flame retardant finishing of synthetic fabrics. In this work, vinyltrimethoxysilane（VTMS） was introduced onto the polyamide66（PA66） surface by microwave grafting to improve the fire performance. The chemical structure of the grafted fabric was characterized by attenuated total reflection Fourier transformation infrared spectroscopy（ATR-FTIR） and X-ray photoelectron spectroscopy（XPS）. The thermal stability analysis and flammability evaluation of the grafted samples by thermogravimetric analysis（TGA）, cone calorimetry, vertical burning tests and limiting oxygen index（LOI） demonstrate that the presence of grafting chains significantly reduces the dripping tendency and decreases the heat release rate of polyamide66（PA66） fabric. The surface morphology observed by scanning electron microscope（SEM） indicates that VTMS can not only promote the formation of protective layers, which prevent the substrate from further thermal degradation, but also promote the char formation ofPA66 substrate during combustion.

Ltd. Beijing 100079 China

On-road emission and fuel consumption （FC） levels for Euro Ⅲ and Ⅳ buses fueled on diesel and compressed natural gas （CNG） were compared, and emission and FC characteristics of buses were analyzed based on approximately 28,700 groups of instantaneous data obtained in Beijing using a portable emissions measurement system （PEMS）. The experimental results revealed that NOx and PM emissions from CNG buses were decreased by 72.0% and 82.3% respectively, compared with Euro IV diesel buses. Similarly, these emissions were reduced by 75.2% and 96.3% respectively, compared with Euro III diesel buses. In addition, CO2, CO, HC, NOx, PM emissions and FC of Euro IV diesel buses were reduced by 26.4%, 75.2%, 73.6%, 11.4%, 79.1%, and 26.0%, respectively, relative to Euro Ⅲ diesel buses. The CO2, CO, HC, NOx, PM emissions and FC factors all decreased with bus speed increased, while increased as bus acceleration increased. At the same time, the emission/FC rates as well as the emission/FC factors exhibited a strong positive correlation with the vehicle specific power （VSP）. They all were the lowest when VSP 〈 0, and then rapidly increased as VSP increased. Furthermore, both the emission/FC rates and emission/FC factors were the highest at accelerations, higher at cruise speeds, and the lowest at decelerations for non-idling buses. These results can provide a base reference to further estimate bus emission and FC inventories in Beijing.

To improve forecasting and sustained control level of underground pests, trapping quantity of underground pests （black cutworm,mole cricket and scar-ab） by lamps and their field dynamics in Hangzhou district from 2005 to 2011 were investigated in the paper. The results showed that different pests had obvious differences in population dynamic. The black cutworm （Agrotis ypsilon） had several damage peaks （late May, late June and late July） and the moth amount in early period was relatively high. The mole cricket （ Gryllotalpa africana） had two damage peaks （late May to early July, early September to mid and late October）. The scarab （Anomala corpulenta） had one damage peak （late May to late June）. There were periodic changes in total quantity of underground pests among years, and the peak period appeared in the year of 2005, 2007 to 2009 and 2011, respectively. On this basis, temperature, humidity, rainfall and light were used as forecas- ting factors, using the method of stepwise regression, 19 factors with significant correlation were screened out and prediction models for occurrence quantity and oc- currence period of the three pests were established. By using accuracy degree judge model for verification, the score values of prediction model for occurrence quan-tity and occurrence period of the three underground pests were more than 58 and 70, which indicated that the historical coincident rate and prediction accuracy of estabhshed prediction models were good.

目的:考察川芎嗪单独及与冰片配伍鼻腔给药的鼻纤毛和黏膜毒性。方法:以在体蟾蜍上颚黏膜为纤毛毒性评价的动物模型,考察对蟾蜍上颚纤毛持续摆动时间、纤毛持续运动百分率和蟾蜍上颚黏膜形态的影响。以扫描电镜观察和病理组织切片考察大鼠鼻腔给予川芎嗪(含川芎嗪100mg/ml)和复方川芎嗪(含川芎嗪100mg/ml,冰片10mg/ml)时鼻纤毛毒性和鼻黏膜细胞毒性,并对停药后纤毛和黏膜毒性的可逆性进行研究。结果:在体蟾蜍上颚黏膜的动物试验中,川芎嗪单用组(含川芎嗪100mg/ml)和川芎嗪与冰片伍用组(含川芎嗪100mg/ml,冰片10mg/ml)的蟾蜍上颚黏膜的形态与生理盐水组比较无明显差异。大鼠鼻黏膜纤毛的扫描电镜结果显示川芎嗪单用组和川芎嗪与冰片配伍用组鼻腔给药1w后,鼻纤毛排列稍显杂乱,少数区域有纤毛簇状聚集和脱落现象;病理组织切片显示大鼠鼻黏膜细胞上皮层厚度无明显改变,上皮细胞形状较为规则,未出现毛细血管扩张,但有上皮下区域腺体增生、淋巴细胞浸润等病理表现;停药1w后,扫描电镜观察纤毛受损的情况有所恢复,病理组织切片显示上皮下区域腺体增生及淋巴细胞浸润现象减轻;停药2w后,观察结果和生理盐水组无明显差异。结论:川芎嗪和复方川芎嗪对纤毛和黏膜的毒性轻微且毒性具有可逆性。
